Force or pressure transmitters
Analog / digital transmitter for strain gage bridge load cells - TRFO RS485
The TRFO RS485 is a strain-gauge bridge converter. Measurements are performed in 6-wire or 4-wire technology and are available via the Modbus-RTU serial protocol or the analog output. The analog output can be set to 0/4..20ma or +/-10V. Sensitivity from 1 to 64mV/V, configurable by DIP switch for integer values or via software for real values. We calibrate this module in our own factory. metrology laboratory.
