HVAC Sensors
An HVAC sensor is any device used to measure the conditions of an enclosed space, room or building. HVAC sensors include thermostats, humidistats, carbon dioxide sensors, pressure sensors and more.

HVAC sensors are connected to equipment and regulate air quality. Thermostats measure temperature, switching on and off heaters and air conditioners so that measured temperature matches a predetermined setpoint. Humidistats measure humidity and work with thermostats and heaters to protect equipment from condensation and corrosion. Carbon dioxide sensors monitor the quality of the air and regulate fresh air with ventilation adjustments. Pressure sensors monitor and adjust air flow.

HVAC sensors are ultimately responsible for the efficiency of the entire HVAC system and the overall air quality of the environment.

WD-100 Series Image
The WD100 is a microchip-based device that uses gold-plated sensing probes to detect the presence of water or other conductive liquid. The WD100 is powered by an AC or DC source, 14 - 30 volts. It features normally open and normally closed (form C) relay contacts rated at 5A @ 120 VAC/30 VDC for connection to a monitoring system, or direct control of another device. The mounting legs will allow a sensing height adjustment from 0" to 1/2". The WD100 is designed to signal an alarm if one or more of three conditions are met: water is detected, power is lost to the unit, or if there is an internal failure.
The WD100 provides the highest level of water detection confidence.
