Introducing the TDEPD Field Programable Pressure Transducer with Built In LED Display, Analog Output and Relays

Pressure transducer with an LED readout scrolls 360° or can be locked in position. Color-coded display tells you if pressure is excessively high or low without reading values.


  • Totally electronic design
  • 4-digit, bi-color display (Red or Green)
  • High or low current, relay output
  • Custom pressure ranges and outputs available up to 10K pig
  • Analog and digital outputs
  • Solid stainless steel header/diaphragm
  • Pressure ranges up to 10K psi
  • UL recognized component
  • 0.5% accuracy
  • Factory-programmable set point and hysteresis
  • Spike Monitoring Technology ™
  • Oxygen cleaning available

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.
