From analog signal to industry standard

The Pt100- and the Pt1000-Modbus converter acquire the measuring signal of a Pt100 resp. Pt1000 temperature sensor and make the measured value available for interrogation via Modbus RTU (RS485). Due to the simple address assignment from 1...99 by code switches, up to 99 temperature sensors can be quickly integrated into a bus. Like the other Lambrecht Modbus RTU sensors, the Pt-Modbus converter also have autoconfiguration registers (mapping). Thus they can be automatically recognized by the data logger met[LOG] and created for the measurement with just one push of a button.
