8170–8175 Ultrasonic Level Probe & Transmitter

Brand: Burkert Fluid Control Systems

The Ultrasonic Level Transmitter Type 8170/8175 combines an ultrasonic sensor probe and a remote transducer with a large 8-digit multi-language display in a splash-proof plastic NEMA 4 enclosure for remote mounting.

The transmitter is powered with 18–32 Vdc (optionally 120/240 Vac) and features a three-wire 4–20 mA output for direct controlling a continuous control valve, a PLC or for monitoring. Two optional 3A relays can be configured as alarms or latched for automatic fill or empty operations.
Features
