Kavlico's P593 low pressure differential sensors incorporates a mature ceramic capacitive sensing element in a compact design. Using a 5 Vdc input, this transducer provides a 0.25 to 4.0 Vdc output proportional to pressure. The P593 pressure sensor is offered in a 0-1” or +/- 0.5” pressure range and is widely used in high precision VAV and filter monitoring systems
