Cleveland Controls 21117 Pressure Probe
The Cleveland Controls 21117 is an industrial-grade static pressure probe (aspiration) designed for technicians who require high-accuracy HVAC airflow measurement. Built with a 4-inch aluminum tube, this sensing probe features a 1.25" barbed end compatible with 1/8" to 1/4" ID flexible tubing, ensuring a secure, leak-proof connection to air pressure sensing switches and differential pressure transmitters. Its 1.5-inch 4-hole mounting flange allows for a rigid installation into 3/8-inch duct holes, providing a stable duct pressure sensor interface even in high-velocity environments.
For optimal performance in building pressurization applications, this aspiration probe must be installed perpendicular to the airstream so the tip opening remains parallel to the flow. When integrated with differential pressure switches, the Cleveland Controls 21117 effectively monitors filter pressure drop and proves fan operation. The probe’s 5.25-inch overall length and 1/4-inch diameter make it a versatile standard for commercial HVAC maintenance and ductwork diagnostics.
Key Benefits- Precise Aspiration Sensing: Engineered for accurate static pressure readings without interference from velocity (total) pressure.
- Contractor-Ready Durability: Rugged aluminum construction resists corrosion and environmental wear in demanding mechanical rooms.
- Universal Compatibility: The 1.25 inch barbed end fits standard HVAC tubing used across most major control brands.
- Secure Flange Mounting: 4-hole 1.5-inch flange prevents probe shifting or vibration-induced signal noise.
- How do I position this probe for the best reading? Mount the probe 5 to 8 duct diameters downstream from elbows or obstructions. Ensure the tip is parallel to the airflow to sense static pressure only.
- Will this work for sensing air flow in a dirty environment? Yes, but ensure the aspiration holes remain clear. Using this with an air pressure sensing switch is a standard way to prove air flow and monitor filter loading.
- Can this be used for total pressure measurement? No, this is an aspiration (static) probe. For total (impact) pressure, look for the 21121 and orient the tip into the airstream.
