Programmable temperature transmitter with mineral insulated probe and Modbus RTU digital output (RS485)
Temperature transmitter with overmolded IP67 casing with M12 output connection. By using a single cable, it is possible to build a sensors network which can be directly connected to a PLC or a PC equipped with a supervisory software (SCADA). These devices are equipped with M12 connectors allowing for an easy and quick installation with degree of protection IP67.
