865 Series Differential Pressure Transducer
Brand: Gems Sensors, IncThe 865 Series are very low-pressure transducers for ranges as low 0.25" WC and feature ±1% full scale static accuracy.
Primarily used in Building Energy Management, these transducers are capable of measuring pressures and flows with the accuracy necessary for proper building pressurization and air flow control.
865 Series transducers utilize an all-stainless steel micro-tig welded sensor that allows up to 10 psi overpressure (in either direction) with no damage to the unit.
All sensor components have thermally matched coefficients, which promote improved temperature performance and excellent long-term stability.
