From analog signal to industry standard

The Pt100 Modbus converter acquires the measuring signal of a Pt100 temperature sensor and makes 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 Pt100 Modbus converter also has autoconfiguration registers (mapping). Thus it can be automatically recognized by the data logger met[LOG] and created for the measurement with just one push of a button.

Temperature sensors

are the objects to be measured and the starting point for the right choice of sensors. The soil sensor (828) is water­proof and is used to measure air, water and soil temperatures precisely. Instrument (8241), which includes radiation protection and a mounting rod, is best suited for measuring temperatures about 5 cm above ground (grass level). For measurement of air temperatures in higher areas, sensor (8281) is most suitable.
