Environmental Sensors

Liebert TW420 and THW420 Environmental SensorsTemperature and humidity sensors provide accurate sensing of room temperature and humidity, transmitting the data via 4-20 mA output signal to the Liebert Universal Monitor.

Temperature and Humidity Sensors

The Liebert TW420 and THW420 temperature and humidity sensors provide accurate sensing of room temperature and humidity, transmitting the data via 4-20 mA output signal to the Liebert Universal Monitor.

The Liebert TW420 and THW420 sensors provide temperature and humidity inputs to the Universal Monitor.

  • Liebert TW420 is a wallmounted, remote temperature sensor that provides a 4-20mA signal. Monitored temperature range is 45°F to 96°F (7°C to 35°C).
  • Liebert THW420 is a wallmounted, remote combination temperature and humidity sensor that provides two 4-20mA signals. Monitored temperature range is 45°F to 96°F (7°C to 35°C), with 0 to 100% RH.
