Order Note
The material of measuring medium should be compatible with the stainless steel.If it is corrosive,pls specify its material in detail.
Please note in the order if you need zero pressure as negative pressure.
Please note it in detail if your application environment is critical or the elments which may influence the pressure transmitter normal operation existed.
The structure and demension of the pressure transmitter can be used for most of the application occasions,if your application space is too small or having
other requirements to the transmitters,please specify it in detail.
All specifications are subject to change.Contact Gaohua for specifications and engineering drawings that are critical to your application.Drawings contained
