The Liebert TW420 and THW420 temperature and humidity sensors enhance data center monitoring by accurately sensing room temperature and humidity, then 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.
