1-Wire sump temperature sensor (3 m)

The TGL-40 sump temperature sensor is designed for measuring the temperature of gaseous or liquid substances. With a suitable thermowell, the sensor can be also used inside pipelines. The sensor utilizes the DS18B20 temperature chip placed within a metal sheath (IP67 protection), the 3 m cable features RJ45 connector for easy connection. For communication with the control system, the sensor uses the 1-Wire bus and can be installed in any system compatible with the DS18B20 chip. The product underwent a metrologic inspection.
