Views Endress+Hauser 3 Radarsensor USR30 Function and system design Measuring principle The Micropilot is a measuring system, operating based on the time-of-flight method (ToF). It measures the distance from the reference point to the product surface. The radar signals based on the

"Frequency Modulated Continious Wave" (FMCW) principle are emitted by an antenna, reflected off the product surface and received again by the radar system. Input Measured variable Measured process variables Level / Distance: 0 to 35 m (0 to 115 ft) Measuring range Maximum measuring range: 0 to 30 m (0 to 98 ft) for solids and liquids with permittivity > 1.9 Increased measuring range: 30 to 35 m (98 to 115 ft) for solids and liquids with the following application conditions:

Only for media with a high permittivity value, such as water. No turbulent surfaces No increased inhomogeneous atmosphere (increased amount of dust particles, gas phases, high humidity or similar) Calibration parameter Ground B Measured distance D Empty calibration (= zero) E Full calibration (= span) F Level in %

L Blocking distance BD Full distance FD Empty distance ED Extended length EL Radarsensor_Abgleichparameter 4 Endress+Hauser Radarsensor USR30 Medium Media: solids and liquids Usable measuring range for solid applications The usable measuring range depends on the reflection properties of the medium, the installation position and possible interference reflections. Ammonia (pure - 100 %) Acetone Measurement of the following media with absorbing gas phase For example the following media Methylene chloride Methyl ethyl ketone Propylene oxide VCM (vinyl chloride monomer) To measure absorbing gases, either use a guided radar, measuring devices with another measuring frequency or another measuring principle. If measurements must be performed in one of these media, please contact Endress+Hauser. Operating frequency 80 GHz The operating frequency is for measurement purposes only. Blocking distance No signals are analyzed within the blocking distance (BD) For this reason, the blocking distance can be used to suppress interference signals (e.g. from condensate) near the antenna. Factory setting: automatic The blocking distance (BD) can be set. The set default value is 0 mm. The setting is made in the blocking distance parameter. A0041499 Sensitivity The sensitivity of the sensor can be configured using a "sensitivity parameter" (high, medium, low).

tance to the medium and can be used to monitor the level of liquids and solids. 1.1 General functionality The sensor uses an UART interface for communication. Measurements must be triggered through a spe-

cial command and cannot be done in continuous mode. After a measurement is finished the ready state is signalized meaning that the measurement data can be read through the interface. t b u a l r e t h c i n G K

Using the time-of-flight method the distance to the medium is calculated. According to the tanks parameters a level percentage is determined and the internal algorithm evaluates the measure-

ment quality. If a measurement fails, the error is indicated through the ErrorState parameter. Version:

. n e t l a h e b r o v e t h c e R e l l A Customer Manual USR30 4 Sequence/Timing The USR30 is designed to be permanently powered or only powered up for each measurement. The recommended startup sequence is as followed (Step 1 and 2 can be ignored if the power supplys voltage is already stabilized):

1. Switch on VDD_RADAR and VDD_IF with RESET being HIGH. 2. Set RESET to LOW when supply voltages are stable. 3. The USR30 boots up and sets SIG1 to HIGH when finished (< 250 ms). 4. Optional: change configuration of USR30 using UART commands. 5. Trigger measurement using UART command. The USR30 sets SIG1 to LOW during measure-

ment and calculation process (< 100ms). 6. After SIG1 is set to HIGH state by the USR30, the measurement data can be read out using UART commands. Alternatively, the trigger measurement address can be read and if the value returned to OFF the data can be requested. 7. To turn off the device just turn off the power supply.

The length of the frame starts from CID and ends before the CRC. LEN is the low byte of the frame length, ADL the high byte. TID is the transfer ID to identify the response of a request. CID is the command ID. The only commands supported are 0x35 (Read) and 0x34 (Write). The parameter to read/write is selected in the PID bytes. For USR30 the Instance is always 0. The CRC is calculated over all data except STX and is defined as followed:

It is like the request frame, but instead of the PID the response has a status byte STA that is always 0 for USR30. Figure 7: USR30 read response Figure 8: USR30 write response The CID of the response is the CID of the request with an additional bit indicating if the request was success-

ful. On success, Bit 8 (MSB) is set, otherwise Bit 7 is set. Therefore, for a read request (CID=0x35), ACK is 0xB5 and NACK is 0x75. STA is always 0 for USR30. On unsuccessful request, an error code ERR is given as 2-byte data. C I L B U P

02 06 00 59 B5 00 40 8B C9 42 5A 71 6 Offset Calibration It is recommended to do an offset calibration of the sensor after installation in a housing. From factory the sensors are calibrated to the flat plane of the recommended horn construction. If a different construction is used the sensor must be recalibrated to the new reference plane. The measured reference length shall be 1m. The following command sequence has to be executed for a calibration:

1. Write default Z-Offset value: 85 = 0x42AA0000 02 0B 00 00 34 DD 05 00 9B 13 00 00 00 AA 42 05 17 2. Read reference length (e.g. Laser reference1) 3. Trigger Measurement 4. Read Error Flags C I L B U P a. Verify, that no Error Flags are set 5. Read Distance 6. Calculate Z-CORRECTED = DISTANCE REFERENCE + Z-DISTANCE 7. Write Z-CORRECTED to Z-Offset parameter 1The accuracy of the reference can directly affect the accuracy of the sensor.

n o i t a c i f i s s a C l 7 Echo Curve The echo curve is stored in an array of 2048 unsigned 16-bit integers. Due to its length, it is split in 3 sepa-

rate parts each of which has to be read out individually. Further the echo curve has to be scaled to cor-

rectly map the peaks with the corresponding distance. 7.1 Reading Use the following three commands to read all three curves. EchoCurve1 request:

16 of 20 Customer Manual USR30 8 Installation The following things have to be considered when installing the USR30:

The sensor has to be installed horizontally and parallel to the tanks ceiling. Otherwise, undesired re-

flections can cause interference with the signal. The radar antenna must not be covered by metal objects. Do not mount any objects which may cause interference, such as tank internal fittings, grids or agita-

tors, below or in the direct vicinity of the radar. t b u a l r e t h c i n G K
