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.

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.
