KMC Controls CSP-4702 Analog VAV Differential Pressure Controller / Actuator [New] en Tempe, Arizona, USA

. . . . . The compact analog electronic CSP-4702 is a combination controller and actuator designed primarily for use on pressure-independent VAV (Variable Air Volume) terminal units. It also has applications as an electronic static pressure controller. (For sample applications, see the application guides.)Differential air pressure is sensed by an internal digital CMOS sensor connected via 1/4″ FR tubing to an SSS-1000 series airflow sensor. The 0 to 2″ wc (0 to 500 Pa) differential pressure sensor is internally linearized and temperature compensated for high accuracy down to very low pressures.The CSP-4702 offers full-range flow control of VAV terminal units when used with the CTE-5202 electronic room thermostat. Air flow control limits may be set at the thermostat or internal to the CSP-4702. An adjustable mechanical stop is also included.The CSP-4702 accepts a 2 to 10 VDC control signal from the thermostat.
