Lutron Humidity Transmitter (TR-RH2W) 2 Wire

Lutron Humidity Transmitter (TR-RH2W) 2 Wire

The TR-RH2W is a 2-wire humidity transmitter designed for precise and reliable monitoring of humidity levels. It features a high-precision capacitive sensor with a 4-20 mA output, making it suitable for integration with various controllers, alarms, and indicators for remote humidity monitoring. With a measuring range of 10% RH to 95% RH, it offers durable operation under different environmental conditions. The device can be powered through its signal wiring, ensuring a simplified setup and robust performance in industrial and environmental monitoring applications.

• Measuring range: 10 %RH to 95 %RH.
• Output: 4 to 20 mA, where 10 %RH = 5.6 mA, 50 %RH = 12 mA, and 95 %RH = 19.2 mA.
• 2-wire configuration for both signal and power supply.
• High precision capacitive humidity sensor.
• Compatible with 4-20 mA controller/alarm/indicator (e.g., CT-2012) for remote monitoring and control.
