Model 770 Pressure Transmitter

Description

The Model 770 Pressure Transmitter uses a solid machined diaphragm sensor, which provides excellent durability and repeatability. 770 has both IS and Explosion Proof approvals, and can measure pressures up to 100K psi. A wide variety of wetted surface materials, process connections and electrical connections are available, and special wiring configurations are easily accommodated.
