Z series pressure transmitter (Gauge type)

Guest

Dear Sir,

I have question which drils my brain always. Everybody (who are expert at these field here) says that gauge type transmitter does not measure the pressure agains the environment (atmosphere).

On the otherhand I wanna use it to measure a level of a tank which is an open tank. But I should measure its hydrostatic pressure at the bottom of tank relative to the atmosphere. Something like differential pressure transmitters which one side is opened to air.

No body does not agree with me. But I know that gauge means measurement relative to the athmosphere. Everybody says that measurement room of the sensor is closed to environment and its pressure adjusted 1atm during its manufacturing phase. Yes it is also logical. I do not have any clear explanation of the data sheet of the Z series of transmitters.

Please clerfy me who is right?

Best regrds,
