The Q-Series Room Relative Humidity and Relative Humidity & Temperature Sensors monitor and transmit changes in humidity and temperature to the building control systems. These units are especially suited for applications where precise, stable humidity sensing is required. The new Q-Series sensors use the same housing as their Series 1000 predecessors, but with a totally new internal circuit design and sensing element. Several models are available: humidity only versions (with ±5% or ±2% accuracy) and humidity and temperature sensing versions (also with ±5% or ±2% accuracy). The humidity only units have either a 4 to 20 mA or 0 to 10 Vdc output signal. The combination humidity and temperature units have a current or voltage humidity output, with the temperature output being a matching current or voltage signal. Sensing models (with display or full-featured) are also available. The full-featured models offer a wide range of features and functionality that can be used with a variety of building control systems:
