Differential Pressure Sensors
 |  |  |  |  |
Style A | Style B | Style C | Style D | Style E |
Use these sensors with differential pressure gauges and switches to measure the static pressure drop across air filters, cooling coils, and blowers in air-handling equipment. Install them in duct through a hole and connect to your gauge with tubing.
Style D—Style D is held in place with a magnet so you can move it for use in multiple locations.
Pressure Tubes—Sensors with pressure tubes give more accurate measurements in applications with high air flow.
