RH/T | Economy | Wall | 3% | 4-20 | 10k T3
Features
- Monitor humidity and temperature with a single device reduces installation costs
- Semiconductor temperature transmitter, or popular thermistor/RTD sensors available
- Housing is low-profile perfect for schools and museums
Description
HEW Standard Series wall mount humidity transmitters offer high performance in an easy to install housing at an affordable price. The thin-film capacitive sensor element provides high accuracy and performance, great long-term stability, and full recovery from saturation. Temperature sensing options are also available. The wall housing was created using sophisticated thermal analysis techniques for optimum airflow. It is ideal for schools and other applications requiring exceptional durability and a discrete appearance. All Standard models come with a standard one-year warranty.
Application
- HVAC economizer control
- Managing energy systems
- Facilitating ASHRAE standards for environmental control
