M1500 – digital pressure transmitter

The digital pressure transmitter M1500 is a highly accurate pressure control system based on microprocessors for the measurement of differential, gauge or absolute pressures with an accuracy of better than ±0.025 % F.S on the digital interface.


M1500 digital pressure transmitters are available with various interfaces and optionally also with an analogue output. The digital interface enables the configuration and retrieval of data via PC as well as the networking of transmitters (RS485). The digital interface of the analogue output version supports only the configuration of the transmitter.
