Series DPT Digital Pressure Transmitter with Switches

Specifications - Installation and Operating Instructions

The Series DPT Digital Pressure Transmitter with Switches combines a large,

14-segment LED display with two programmable solid state switches into one compact unit. A unique, 3-way rotating design allows the DPT to meet specific installation requirements without any retrofitting. The display and electrical connection can be rotated independently to maximize visibility while still orienting the electrical connection in the best position for the cable connector. Large, ergonomically designed push buttons allow for quick/easy programming and thinfilm piezoresitive sensor technology guarantees long-term reliability and stability.

INSTALLATION

When installing gage always use a hex at the base of the housing to tighten the gage to a mating fitting. Do not apply wrench to housing.
