Lower installation costs with the Series 676 Duct Pressure Transmitter. The Series 676 Transmitter incorporates a pressure sensor and a static pressure tip into a single unit, eliminating the need for costly control panels and reducing installation time. Each transmitter has three (3) field selectable pressure ranges.

A micro-machined glass-on-silicon capacitance sensor provides a high level, fully conditioned and temperature compensated 4-20 mA output. Rugged NEMA 4 (IP56) enclosure with gasketed cover protects the electronics and sensing element from condensation, corrosion and dust. Units also feature short circuit and reverse polarity protection.
