Precise Temperature Compensation
The PX137 series has been discontinued. Please contact our Pressure Engineering department.
The PX137 Series pressure transducers use state-of-the-art micro-machined silicon pressure sensors in conjunction with stress-free packaging techniques to provide highly accurate, temperature-compensated pressure measurements for the most demanding applications.

Excellent Quality / Price ratioThis devise is easy to set-up. The absolute reading precision was not a concern for my application. The response time was adequate. Perfect for laboratory application. Not suitable for harsh environment.

Low precision for a high priceI have used and tried several pressure transducers from Omega for lab-grade applications and this one has poor accuracy despite the price. When transformed to pressure units, values always fluctuate plus/minus 0.2 kPa. Although this may be low and corresponds to about 0.2% FS I have found the PX141 to be far more precise, with virtually no fluctuations in voltage output for the specified pressure ranges. It is a shame that Omega has decided to discontinue the PX141 which offered far better precision for a similar price. I would not purchase the PX137 again and would recommend to use the PX26 instead, which although has a bit lower accuracy, is more fairly priced. Also, I would like to point that these fluctuations in voltage have a period of 10-20 seconds, so they are hard to get rid off by using a moving average without loosing significant temporal resolution.
