Product Specification

TDEPD Series Pressure Transducer DESCRIPTION
What makes the patented TDEPD Series stand apart is the unique LED display - which allows for 360° scrolling, or you can lock the display in one location. It also features field-programmable set points and hysteresis.

Because it is built on Transducers Direct’s TD1000 technology, the TDEPD Series incorporates redundant sensing elements,allowing for notification that the sensor needs to be replaced should one of the sensing elements fail (maintenance mode), eliminating operational downtime.

The TDEPD Series pressure switch/transducer comes standard with one digital output and optional analog output available. Unit operates from 10.5 to 28 VDC, and is IP67 certified.

TDEPD Series Pressure Transducer FEATURES
• Maintenance Mode (redundant sensing notification)
