Cleveland Controls RSS-498-13 SPDT Air Pressure Sensing Switch Kit 1.0"-4.0" WC

The Cleveland Controls RSS-498-13 SPDT air pressure sensing switch is essential for HVAC systems. It is designed to work within the pressure range of 1.0” to 4.0” water column, which is useful in measuring low-pressure differentials across most of the HVAC components. This switch works with help of a change in the pressure of air and makes a particular circuit on/off. When the sensed pressure is within the range, the switch makes the circuit and initiates a control action such as sounding an alarm, starting a fan, or changing the position of dampers. This precise pressure sensing capability makes the HVAC systems more efficient and effective because the maintenance is done in advance and the airflow is checked.
