Absolute Gauge and Pressure Sensor OK for Vacuum?

Hardware

Hello,

We have a few of these 1/4" NPT Gauge and Pressure sensors deployed. Are they OK and rated for Vacuum (negative pressure)?

A few of the ones we have are already registering negative pressure, so I think they are, but I wanted to double check before I deploy more for that specific purpose.

This one should not be used in vaccume. long term exploseure could damge sensor.
To measure -ve pressure we will need to build it with a dif sensing element.
