DM231 Magnetostrictive Level Transmitter
Brand: DrexelbrookThe Drexelbrook DM231 is an explosion proof liquid level transmitter offering high accuracy measurements based on the magnetostrictive sensing technology.
The DM231 comes with a Modbus RTU digital output (optional analog output converter available) for total level, interface level and temperature sensor outputs.
Sensors are available in 316SS rigid designs with a choice of single or dual NPT mountings. Temperature sensors are evenly distributed over the active length of the rigid 316SS tube.
Due to a wide selection of floats and mounting accessories this level transmitter fits virtually any application.
The DM231 level transmitter is FM approved for Class 1 Div. 1, Zone 1 Explosion Proof hazardous area installations. It is easy to install and requires no calibration.
