Humidity and Temperature Transmitters RHT-Wall or Duct Mount NOVUS

Highly Accurate & Configurable Monitoring for Your Environment

For precise control over your climate and processes, you need sensors you can trust. The NOVUS RHT-Wall (WM) and RHT-Duct (DM) series of humidity and temperature transmitters are engineered to deliver superior accuracy and stability for your most critical applications.

These transmitters use premium sensors to convert measured values into a reliable, linear 4 to 20 mA signal. The microprocessor-based circuit allows for full configuration of the output range using the optional TxConfig PC interface and Windows-based software, giving you complete control. Whether you need a simple wall-mounted sensor or a robust solution for air ducts, the RHT series provides the reliable and versatile performance you need.

Key Features & Benefits

• Exceptional Accuracy & Stability: Incorporates high-performance sensors for stable and accurate measurement of both relative humidity and temperature, ensuring reliable data for your systems.

• Versatile 4-20 mA Output: Provides a standard, two-wire, loop-powered 4-20 mA or 20-4 mA output signal, easily integrating with most industrial control systems and PLCs.

• Fully Configurable: The humidity signal can be configured as either a relative humidity or dew point output, giving you the flexibility to adapt the transmitter to your specific application.

• Two Models for Easy Installation: Choose between the RHT-WM model, specifically designed for wall-mounted applications, or the RHT-DM version, which is ideal for duct and through-the-wall installations.

• Advanced Safety & Protection: Features internal protection against reversed voltage wire polarity, safeguarding the device and your system from wiring mistakes.

• Galvanic Isolation: Output signals are galvanically isolated, preventing ground loops and electrical interference between outputs.

• Durable & Secure Connections: The PG7 cable gland provides a secure and robust entry point for wiring, protecting internal components from the environment.

• Wide Operational Limits: The electronic module is rated for operation from -10 to +65°C and 0 to 95% RH, making it suitable for a broad range of industrial environments.
