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.

8241 Grass Temperature Sensor

The Grass Temperature Sensor 8241 is a practical device for measuring air temperature at a height of 50 mm above the ground—at grass height. It is designed to provide accurate temperature readings and is weatherproof, allowing it to withstand both rain and sunlight. This sensor is ideal for applications in agriculture, horticulture, and environmental research, where soil temperature plays an important role. Thanks to its robust design and ease of use, the sensor is a reliable choice for anyone needing precise temperature measurements.
