Product Description

The IMP LR pressure transducer has a silicon semiconductor strain gauge sensor element sealed inside an oil filled pressure capsule which produces a high output sensitivity which is particularly advantageous in reducing signal noise at lower pressure ranges.

Unlike many low range pressure sensors which are only compatible with non corrosive gases, the wetted parts of the IMP-LR low gauge pressure transmitter are made up of all stainless steel components and elastomer seals, both of which are compatible with many types of liquids.

Product Help

Country of origin

What is the country of origin of the IMP-LR pressure transducer?

The country of origin is the United Kingdom.

Output response time

What is the response time of the IMP-LR low range pressure transmitter?

It is <10msec.

Barometric scaling

Is it possible to specify a different scaling for the IMP-LR pressure transmitter with a barometric range?

Yes you can select ranges from as little as 950 to 1050 mbar absolute up to 750 to 1250 mbar absolute.

It is possible to provide the standard accuracy of 0.25% for any span from 100 to 500 millibar. For the higher accuracy option of 0.1% the minimum span possible is 350 mbar.

Negative and compound ranges

Is it possible to have negative (e.g. 0 to -100 mbar g) and compound pressure ranges (e.g. -100 to +100 mbar) with the IMP-LR low range pressure sensor?

Yes it is possible to have ranges with minus or combinations of minus and positive pressure ranges:

  • 0 to -50 mbar gauge
  • 0 to -60 mbar gauge
  • 0 to -100 mbar gauge
  • 0 to -250 mbar gauge
  • 0 to -400 mbar gauge
  • 0 to -600 mbar gauge
  • 0 to -1000 mbar gauge
  • -50 to +50mbar gauge
  • -60 to +60mbar gauge
  • -100 to +100mbar gauge
  • -250 to +250mbar gauge
  • -400 to +400 mbar gauge
  • -600 to +600mbar gauge
  • -1000 to +1000mbar gauge

Low cost atmospheric pressure sensor

We are looking for a small, low cost atmospheric pressure sensor with a range of 900 to 1100 mbar absolute or similar, with 4-20mA output signal and G1/4 process connection. The sensor will be used in cooled flue gases?

It is possible to offer a custom scaled 4-20mA output for the IMP LR calibrated to a 900 to 1100 mbar absolute range.

  • SKU ID: s1-implr-0006
  • Pressure Range: 900-1100
  • Units: mbar
  • Range Type: Absolute (0 to +P)
  • Output Signal: 4 – 20mA, 2-wire (5)
  • Non-Linearity and Hysteresis: 0.25% FS (standard) (A)
  • Thermal Zero Shift: 0.04% FS per °C (standard) (4)
  • Electrical Connection: Large DIN plug (standard) (B)
  • Process Connection: G1/4 male DIN 3852 (A)
  • Media Exposed Seals: Viton (V)

Lowest absolute range

What is the lowest absolute pressure range possible with the IMP-LR?

The lowest possible absolute range for the IMP-LR series is 0 to 350 mbar abs, and the accuracy is specified as 0.5% full scale.

Engine crankcase vacuum measurement

I’m looking for a sensor to measure engine vacuum in a small engine crankcase from -1 to 0 psi with a 4-20mA output?

We would suggested the following specification for your application:

  • SKU ID: s1-implr-0001
  • Pressure Range: -1 to 0
  • Units: psi
  • Range Type: Positive Gauge (atm to +P)
  • Output Signal: 4 – 20mA, 2-wire (5)
  • Non-Linearity and Hysteresis: 0.25% FS (standard) (A)
  • Thermal Zero Shift: 0.04% FS per °C (standard) (4)
  • Electrical Connection: M12 4 pin connector (G)
  • Process Connection: G1/4 male DIN 3852 (A)
  • Media Exposed Seals: Viton (V)

Zero output at 0V or 5V on negative range

If I order the 0-5 volts output version with a 0 to -150 mbarg range, will the signal coincide with 0 mbar or the -150 mbar end of the scale?

You can order order either. 0 volts at 0 mbar is the recommended configuration  because you can easily tare the zero at ambient pressure.
