Part number: 100840
Part name: Pressure Transducer
Description:
The relative pressure transducers type 10.0840.XX are devices for the measurement of pressure of air or water and are designed and tested to be used in heating and industrial circuits. The pressure transducer is based on a piezoresistive silicon chip with four resistors connected in a Wheatstone bridge, and it includes the signal conditioning electronic circuit, which is fully digitally calibrated and compensated on board, in order to provide an amplified output voltage proportional to the applied pressure. The pressure transducer type 10.0840.XX can be customized in order to have any ratio of pressure vs. output voltage signal (between 0 - 7bar vs. 0.5 - 4.5 Volt).
General characteristics:
  • Relative pressure transducer
  • Pressure range: typically 0 - 4 bar (customisable 0 - 7 bar)
  • Output signal: typically 0.5 - 2.5 Volt (customisable 0.5 - 4.5 Volt)
  • Electronic fully integrated in the device
  • Ratiometric output signal digitally calibrated, compensated and amplified
  • connection on demand
  • Electrical connection: connector 3-pole, Rast 2.5 mm, Lumberg 3521-03-K39 or equivalent
  • IP00
