Product advantages
From analog signal to industry standard
The Pt100 and PT1000 Modbus converters record the measurement signal from a Pt100 or Pt1000 temperature sensor and make the measured value available for retrieval via Modbus RTU (RS485). Thanks to the simple address assignment of 1...99 via code switches, up to 99 temperature sensors can be quickly integrated into a bus. Like the other Lambrecht Modbus RTU sensors, the Pt Modbus converters also have auto-configuration registers (mapping). This allows them to be automatically recognized by the met[LOG] data logger, for example, and set up for 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.
