on the 3" gauge, what are the dimensions of the bolt hole pattern on the perimeter and how thick is the gauge overall and at the bolt location?
Thank you for contacting Omega. The information you requested is located one page 36 of the product manual. Thank you.

Can this gauge be used on a Diesel line?
Hello,
Thank you for reaching out to Omega. the wetted parts on this gauge are 17-4 SS
You will have o check chemical compatibility of the gauge with the wetted parts. Also keep in mind that these models are not intrinsically safe.

Thank you for the bolt pattern dimensions, how thick is the 3" gauge?
Thank you for your inquire
The depth is about 2 to 2 1/4
hope this was helpful.

I dont remenber the passaword i have set in my DPG9145. How can i reset this password?
Thank you for contacting Omega. If you have forgotten the password you entered for the DPG9145 gauge you can try using the default password which is 12045. This should allow you to enter the CONFIG menu and use the SETPW option to enter a new password. If you are still unable to access the CONFIG mode you should contact our Pressure and Strain engineers for further assistance. Thank you.

I need to be able to connect this gauge to a data logger. Is this possible with this gauge?
If you purchase the loop powered version of this gauge you would be able to connect the data logger input by wiring the gauge, power supply and data logger in series to read the 4 to 20mA output signal from the gauge.
