Measuring principle The core component of the UTR30 radar module is a radar sensor, 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 Continuous Wave" (FMCW) principle are emitted by an antenna, reflected off the product surface and received again by the radar system. Process ■ The measurement can be carried out directly through tanks -> This is only possible for electrically non-conductive tank walls No contact is made with the process medium. Measured variable Measured...

Medium Media: solids and liquids The usable measuring range depends on the reflection properties of the medium, the installation position and possible interference reflections. Measurement of the following media with absorbing gas phase For example the following media ■ Methyl ethyl ketone ■ 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. The operating frequency is for measurement purposes...

Protocol-specific data The UTR30 has the following read and write parameters: Reference operating conditions Maximum measured error Pressure = 960 mbar abs. (14 psi) ±100 mbar (±1.45 psi) Humidity = 60 % ± 5 % Reflector: metal plate with a diameter > 1m (40in) No major interference reflections inside the signal beam Frequency mode 1: default setting of 77 to 81 GHz The accuracy is the sum of the non-linearity, non-repeatability and hysteresis. For liquids: Non-repeatability is already included in the accuracy < 1 mm (0.04 in). Offset or zero point can be eliminated by entering a correction during...

Materials ■ Radar antenna: Plastic PBT ■ Coupling adapter: PPS GF40 (metallized) ■ Enclosure: Plastic PBT/PC • Seal: TPE Supply voltage The radar module offers various options with regard to the output signal. The supply voltage must be considered depending on this. The radar system requires 2 supply voltages: Digital interface: 1.7 to 3.6 VDC (It is possible to cover both supply voltages with one voltage source). Power consumption ~32 mW static ~1000mW peak for <10ms during measurement Electrical connection and pin The radar module offers the following connection options:

Mount header 2x6 pins Connector plug

Installation instructions Safety notes for installation For work on and with the device: Static sensitive devices. ► Handle only at static safe work stations! Beam angle Positioning ■ Mount the measuring device in a horizontal position so that it is parallel to the tank ceiling. Otherwise, undesired reflections from the surroundings can cause interference signals. ■ The radar antenna should never be covered by metal objects. ■ Do not mount any objects which may cause interference, such as tank internal fittings, grids or agitators, below or in the direct vicinity of the radar (see the graphic...

"Frequency mode" parameter The frequency mode parameter is used to define country or region-specific settings for the radar Changing the frequency mode parameter is described in the Operating Manual Radar. ■ Mode 1 (Default): Continent Europe, USA, Australia, New Zealand, Canada, Brazil, Japan, South Korea, Taiwan, Thailand (77 to 81 GHz) The performance characteristics of the device may vary on the mode set.
