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 configurated as alarms or latched for automatic fill or empty operations.
Features- Teach-In function for easy commissioning provides low Total Cost of Ownership
- Simulation function for system tests under dry run conditions
- 4-20 mA current output for continuous control
- Two relay outputs for ON/OFF control and fail-safe logic
- Easy commissioning due to multi language, menu-guided operation with 8-digit alphanumeric display
- Intelligent echo filter for automatic rejection of perturbating echoes
