The Model 265 is designed to reduce installation costs while increasing overall operating efficiency. At +/- 1% full scale accuracy (optional +/- 0.5%, +/- 0.4% and +/- 0.25%), the Model 265 provides superior positive and negative pressure sensing required for high efficiency air control systems. Its small footprint (189"W x 2.74"L x 1.64"H) is an ideal fit for the tightest matrix. Installation is easy with an integral mounting bracket, 1/4" O.D. tube pressure connections conveniently located the on the face of the unit, and a screw terminal strip for electrical termination.
