NAVIEN 30021482A Water Pressure Sensor

The Navien Tankless Water Heaters 30021482A Water Pressure Sensor is an essential part of Navien’s tankless water heaters. This ensures it controls the water pressure within the unit, although the unit itself is usually manufactured out of brass or more recently stainless steel to prevent corrosion. This sensor has the main responsibility of keeping your tankless water heater running safely and efficiently for you. The sensor transforms water pressure into a proportional electrical signal of 0–5 VDC that the control board of the system requires.
