KMC Controls SSS-1003 Sensor

The KMC Controls SSS-1003 Sensor is a professional-grade differential pressure flow sensor designed for high-accuracy airflow monitoring in Variable Air Volume (VAV) terminal units. This 5-13/32" pitot tube airflow sensor features two sensing points and is engineered to integrate seamlessly with the KMC SSS-1000 series, providing technicians with reliable velocity pressure data. It is physically and functionally identical to the 21-238 airflow sensor, making it a drop-in replacement for building automation maintenance. With 1/4" barbed connections optimized for 3/8" OD polyethylene tubing, the SSS-1003 ensures a secure fit in terminal box ductwork. Whether you are measuring static pressure by rotating the probe 90 degrees or calculating CFM in main or branch ducts, this sensor provides the precision required for modern BAS HVAC systems and individual zone control.

• Precise Airflow Monitoring: Built with two sensing points to capture accurate differential pressure for VAV and fan terminal units.
• Universal Compatibility: Identical to the 21-238 and compatible with KMC CSC-1000, CSC-2000, and CSC-3000 series controllers.
• Durable Construction: Features an integral flange with a foam gasket for a leak-proof seal during ductwork installation.
• Flexible Application: Capable of measuring both velocity and static pressure within a velocity range of 200 to 6,000 FPM.

• What size duct hole is required for installation? A 7/8" diameter hole is necessary to properly seat the sensor probes and flange.
• Can this be used with 1/4" OD tubing? While the sensor has 1/4" nipples for 3/8" OD tubing, 1/4" OD tubing can be used with a 3/8" to 1/4" barb union adapter.
• How do I ensure the most accurate reading? Ensure the airflow arrow imprint on the flange is pointing in the direction of the air stream during mounting.
