Description  
is required, using the Loop Resistance Graph,  
9-30 VDC.  
Ranges 0-1000 psi = 600% of full scale or  
4000 psi whichever is lower.  
The PXT Series pressure transmitter is a state-of-  
the-art instruments providing 4 to 20 mA  
outputs. It features a precision micro-machined  
silicon diaphragm with fully welded stainless  
steel pressure port for greater accuracy, stability  
and a wide range of compatibility.

20,000 psi (27.5 MPa) [275Bar].  
Response Time: Frequency response better than  
2 kHz.  
PXT Series Transmitter Output: 4–20 mA,  
2-wire.  
Insulation: Greater than 10 Mohms @ 500 VDC.  
RFI Protection: To the European standards of  
BS EN 50082-2:1991 in accordance with IEC  
801 parts 1 to 6 for suspectibility to EMC and

Storage Temperature: -65 to 200°F (-54 to  
Silicon technology is used to provide a miniature  
micro-machined diaphragm which is  
electrostatically bonded to a glass substrate and  
is then stitch-bonded within a glass to metal seal  
assembly to provide exceptional thermal and  
stress isolation. This technology assures you of  
high accuracy and stability over a wide range of  
operating conditions.
