OMEGA’s PX1005 Sputtered Thin Film Pressure Transducer was designed for cryogenic service; it can operate in temperatures from -196°C to +149°C (-320°F to +300°F.) Yet, even in these difficult temperatures, it provides outstanding accuracy, long-term calibration stability and reliability. Static accuracy is ±0.25%, and thermal zero and sensitivity shifts over the compensated range of -196°C to +27°C (-320°F to +80°F) are less than ±0.01%/°F. The all-welded stainless-steel pressure cavity and double-isolated case ensures reliability in the tough environments normal to cryogenic service. OMEGA’s thin film technology makes this premium performance possible. The strain gages are sputter-deposited, forming a molecular bond with the substrate. There is virtually no shift, drift, or creep to cause the transducer’s calibration to change. OMEGA’s PX1005 is available in many standard ranges from 15 psi to 1,000 psi. A calibration record is supplied with every unit.

Can I use 0(4)...20 mA between output signal for this product?

Asked by: halilibram
Hello, This unit puts out a mV output over the range. So you will need a signal conditioner to convert the signal to a 4- 20 mA output. Please see the DMD4059 unit

What is the tolerance on excitation voltage? I am specifically interested in using this with 12V excitation as my system has been configured for other PTs with 10V excitation which allow for up to 15V excitation.

Asked by: Liam
Thank you for your inquiry You can use between 7 to 15 vdc
