865 - Air Pressure Sensor

Air Pressure Sensor (865 Series)


  • For Air or Non-Conductive Gas
  • 0.25 to 100 Inches (6.35 to 2540 mm) in W.C. (differential)/±0.1 to ±50 Inches in W.C. (bidirectional)
  • High Proof Pressure

The 865 series air pressure sensors are very low-pressure sensors for ranges as low as 0.25" (6.35 mm) W.C. and feature ±1% full-scale static accuracy. Primarily used in Building Energy Management these transducers are capable of measuring air pressures and flows with the accuracy necessary for proper building pressurization and air flow control. 865 series differential air pressure sensor utilize an all-stainless steel micro-tig welded sensor that allows up to 10 psi (.69 bar)
overpressure (in either direction) with no damage to the unit. All air pressure sensor components have thermally matched coefficients, resulting in improved temperature performance and excellent long-term stability.
