KMC TPE-1474 Low Pressure Transducer

Previous Page

Discontinued  TPE-1474 series Low Pressure Transducers can be used to measure positive, negative, or differential pressure in various ranges. With multiple jumper-selectable pressure ranges available, a single model can be configured to cover the input pressure ranges for different situations.

Output is field selectable between (three-wire) 0-5 VDC and 0-10 VDC voltage output ranges as well as a (two-wire) 4-20 mA current output. The output is fully protected from shorts to ground and connection to power supply.

The piezoresistive sensor is ideal for monitoring the pressure for air or other clean inert gas and is limited only to those media that will not attack polyetherimide, silicon, fluorosilicone, silicone, EPDM, or neoprene seals.

The TPE-1474 can be powered from either a 12 to 28 VAC or 16.5 to 35 VDC power source. The TPE-1474 incorporates a high-impact black ABS, plenum-rated enclosure. The unit may be mounted in any position but is typically installed on a vertical surface with the pressure ports on the right and the cable entrance on the left. The enclosure has a standard 1/2" conduit opening and may be installed with either conduit and a conduit coupler or a cable gland type fitting.

Typical HVAC applications include monitoring of filter differential pressure or for VAV applications. The output signal is factory-calibrated and temperature-compensated for highest startup accuracy and trouble-free operation. Avoid locations where severe vibrations or excessive moisture are present.

DO NOT USE for these applications:

  • Oxygen service
  • Explosive/hazardous environments
  • Flammable or combustible materials
  • Emergency stop devices or any other application where failure of the product could result in personal injury
