The ambient temperature of the electronic components in the handle may be -30 to +85 C. The measured temperature value is transmitted wireless to the receiver of the Wtrans system. The radio frequency within the ISM band is 868.4 MHz or 915 MHz. These frequencies are largely insensitive with regard to external perturbations and enable transmissions in crude industrial conditions. If the recommended antenna wall mounting is used, the maximum open air range is 300 m. The handle contains the transmitter unit of the resistance thermometer. The unit is de-
signed to be resistant against vibrations, oils and acids. The protection class is IP67. The stainless steel thermowell is available with a flat, concentric or oblique insertion tip. The fitting length extends from 50 to 1000 mm. The measuring insert contains a serial Pt 1000 temperature sensor to EN 60 751, Class A in 3-wire-circuit. 5 1 Introduction 1.3 Block structure Figure 1:

Insert battery Step 1 2 3 4 5 6 7 What to do:
Screw open the handle counter-clockwise and withdraw one half of the handle. Pull out the circuit board from the handle by approx. 25 mm. Loosen the screwed clamps of the minus pole and the plus pole by means of a screw driver. Insert the plus pole of the battery into the screwed clamp indicated by (+). Tilt the battery and insert its minus pole into the screwed clamp indicated by (-). Re-fasten the screwed clamps of the minus and plus poles by means of a screw driver. Slide the circuit board back into the handle to the stop. Screw together the handle and the half of the handle in clockwise direction. In doing this, please ensure the correct position of the two black gaskets 7.1 and 7.2 at the two halves of the handle! When replacing the battery, please also replace the two gaskets by those provided with the new battery. CAUTION!
On incorrect polarisation, the probe will not function. Both the battery and the electronics of the probe can be damaged. Please ensure correct polarisation of the battery. 9 3 Prepare Probe 3.2 Safety advice for lithium batteries
www.tadironbatteries.de 3.3 Disposal of lithium batteries Please only replace a lithium battery by an identical type. Please dispose of all batteries in accordance with the statutory regulations according to the Circular Economy Act and the Waste Act as well as the local provisions. The contact points of batteries that have not completely been electrically discharged must be insulated. Disposal together with domestic waste is expressively prohibited. You can deliver them cost-free at local collection points or in retail shops in your prox-
imity. 3.4 Apply colour code of the probe Figure 4:
Apply colour code onto the probe In the factory, the probe is provided with four coloured silicone rings (white, green, red and blue), by means of which the probe can unambiguously be optically classi-
fied. These rings can be individually combined and are slid onto the shaft of the probe. In total, 25 options of colour combination coding can be obtained through this. 10 4.1 General remarks on wireless transmission 4 Range of Transmission Radio signals are magnetic waves with their signal becoming weaker on their path from the probe to the receiver (this phenomenon is referred to as loss). Both the elec-
tric and the magnetic field strength are decreased inversely proportional to the squared distance between the probe and the receiver. In addition to this natural limitation of the range of transmission, a reduced transmis-
sion range can also occur due to other circumstances:
Reinforced concrete walls, metal devices or surfaces, heat insulation or metal evaporated heat protection glass reflect electro-magnetic waves and therefore a so-named radio shadow or blind spot occurs behind such objects.
Radio shadows within the transmission link
The antenna is installed in too low a position, therefore mount antenna in as high a position as possible above the floor within a visual range between probe and receiver. A few guiding values on penetration by radio signals:
Materials wood, gypsum, non-laminated glass walling/brickwork, chipboards/fibreboards glass-fibre reinforced concrete metal, aluminium casings Penetration 90 to 100%
65 to 95%
10 to 90%
0 to 10%
The maximum transmission range between the probeprobe and the receiver is 300 meters in a free field. Ideal reception can be obtained if visual contact can be main-
tained between the receiver and the probe. In case the receiver is installed in a switching cabinet, behind concrete walls or con-
crete ceilings, it is indispensable for the antenna to be installed in a wall-mount fash-
ion and including an antenna conduit. 4.2 Impairment of the range of wireless transmission Collision due to prevalence of too many probes For a comparatively large number of probes, the transmission interval should not be set too short, as otherwise the transmission frequency will superfluously be occu-
pied. A short interval means a higher volume of data on the selected frequency, which can lead to collisions with other probes. Through such collisions telegrams might be destroyed during radio transmission. 11 4 Range of Transmission Figure 5:
Telegrams of one probe are transmitted to the receiver collision-free. Figure 6:
Telegrams of various probes increasingly collide in the air as the transmis-
sion medium. Figure 7:
Increase of faults in dependency of the number of probes
(Interval of transmission 1 s) 12 4 Range of Transmission As illustrated in figure 7, the fault curve climbs steeply, if a critical number of probes is reached, as the air, functioning as the transmission medium, is increasingly occu-
pied. Even with as few as two probes, faults cannot be excluded to 100%. For this reason, limitation to a maximum number of 16 probes is recommended for the shortest transmission interval of 1 second, as the fault ratio already strongly in-
creases from 24 probes. External probes However, faults can also arise for a small number of probes; they may be caused by other influences from the environment. External probes might also use the same frequency. In the event that they operate without the Listen before Talk function, they arbitrariliy transmit information on the same frequency without observing the operations and priorities of the other probes. Hence, if for example a probe transmits its radio telegram, and an external probe is simultaneously doing the same, the radio telegram will be destroyed. As the probes are not able to check their own transmission while transmitting, a fault will not be de-
tected. Electrical equipment In crude industrial environment radio telegrams can be destroyed for example through frequency converters, electric welding equipment or insuficiently shielded PCs, audio-visual equipment, electronic transformers, ballasts, etc. Other compo-
nents may also generate bursts that are located on the same frequency. Determination of the maximum number of probes In the event that for a transmission interval of 1sec a number of more than 16 probes is to be installed, a longer transmission interval must be set, in order for the fault rate not to increase further. Example:
16 probes wiht 1 sec transmission interval 32 probes with 2 sec transmission interval For an even further increase of the number of probes, the following example illus-
trates the calculation below. Example:
16 probes with 1 sec transmission interval 48 probes with 3 sec transmission interval
(theoretically) From a transmission interval of 3 sec the telegram will be sent twice. As a conse-
quence, the number of applicable probes is reduced by half. 16 probes with 1 sec transmission interval 24 probes with 3 sec transmission interval
(effectively) The same phenomenon re-occurs for a transmission interval of 60 sec. From this transmission interval, the telegram will be sent three times. Elimination of Faults At the receiving end, fault arising through lost telegrams - regardless whether through external sources of interferrence or through collisions due to a large number of probes - can be bypassed by means of the parameter radio-timeout. The value last 13 4 Range of Transmission received will then be maintained over 2 10 transmission intervals and only then the alarm radio-timeout will be activated (display ----). Through this function short-term faults or interferrences will be bridged and to do not lead to an error. NOTE!
For collisions due to too large a number of probes, the factors number of probes, trans-
mission intervals and at the receiving end radio-timeout must be observed and modified, if applicable. 14 5.1 General remarks on the setup program 5 Setup-Program This setup program may be used to configure probes and receivers with a PC.

For a transmisison interval of > 10 sec, a so-named link telegram will be transmitted by the probe, i.e. for a period of 30 minutes, telegrams will be transmitted in the 10 sec interval as set by the manufacturer, only after this period, telegrams will be sent in the set interval. NOTE!
As soon as the setup plug is plugged in, the probe automatically transmits telegrams in a transmission interval of 1 sec, in order for the receiver to immediately recognised the modi-
fications. After disconnecting the setup plug, the telegrams will be sent in the set transmis-
sion interval. Explications Probe identification (probe-ID) The probe identification (probe-ID) is an unambiguous number with a maximum of 5 positions, that is recognised by the receiver. The ID can individually be modified, e.g. in order to obtain a better overview for a machine. However, it must be observed that one ID is only allocated once within a company, as probes with the same ID cannot be distinguished by a receiver, even for large distances. Transmission interval This parameter defines, in what interval data will be sent to a receiver. The setting of the parameters transmission interval has an effect on the service life of the battery. Therefore, the selection should be made with caution and not exclusively in conside-
ration of the transmission quality. Transmission frequency The transmission frequency determins the frequency band, in which the data will be transmitted to a receiver. In Europe, the transmission frequency has been set to 868.4 MHz, as special regulations have been determined for the ISM band (industrial-
scientific-medical) with regard to transmission interval and transmission power. In the 915 MHz-frequency band ten frequencies may be configured. 18 5 Setup-Program 19 5 Setup-Program 20 6.1 Technical data 6 Appendix Analog input Measuring input Operating temperature range Accuracy of the temperature sensor Output (radio transmission) Probe ID Transmission interval Transmission frequency Transmission power Open-air range Output signal Response time Calibration accuracy of the electronic components Configuration Configurable parameters Voltage supply Lithium battery Service life Pt 1000 to EN 60 751, Class A in 3-wire circuit
