Lower installation costs
with the Series 676 Duct Pressure Transmitter. The Series 676
Transmitter incorporates a presure 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
4-20mA output. Rugged NEMA 4 (IP56) enclosure with gasketed
cover protects the electronics and sensing element from condensation,
corrosion and dust. Units also feature shore circuit and reverse
polarity protection. |
