Vented Gauge (VG) is a pressure referenced to atmospheric pressure via a vent path on the reverse side of the pressure sensing diaphragm.
Vented Cable has a vent tube running through the inside of the cable to provide a vent path between the electrical connections at either end.
Gauge reference pressure is a pressure measured relative to atmospheric or barometric pressure. The most used pressure reference is gauge pressure which is signified by a (g) after the pressure unit (e.g. 30 psi g), and means that the pressure measured is the total pressure minus atmospheric pressure. There are two types of gauge reference […]
Compound range pressure sensor for measuring a negative & positive gauge pressure of 30 inH2O
Freshwater compatible voltage output pressure transducer with a 50 psi gauge pressure range and a 0 to 10 volts electrical signal.
Gauge reference pressure measuring devices read pressure relative to atmospheric pressure. This ensures that the pressure reading is nominally zero when the pressure on the device is released.
We are trying to simulate an environment of 8000 feet in altitude inside a cylinder. We are located in an area that is 200 feet above sea level.
I’m looking for a sensor and panel indicator for a pressure test rig to measure up to 30,000 psi.
Checking vacuum pressure as a positive pressure and also as a negative pressure depending on the type of vacuum equipment being tested
I have level data from a non-vented transducer & barometric pressure data, how do I determine the true depth?
It is not unusual for a pressure measurement device to read slightly above or below zero with no pressure applied.
When it is necessary to present gauge reference pressure data, an absolute pressure sensor can be used in some situations if a gauge pressure sensor is not available. An absolute pressure sensor will measure total pressure independent of atmospheric pressure changes, unlike a gauge pressure sensor which measures pressure relative to atmospheric pressure. To convert […]
There is a loose convention across manufacturers for designating the type of reference that a pressure sensing device has, which can be confusing if you are unfamiliar with specifying this often overlooked but critical specification parameter.
Determining whether you need gauge or absolute reference pressure is a very important to selecting the right pressure range for a pressure instrumentation.
Submersible cable is more expensive because it has to be reinforced to support the sensor plus its own weight in deep holes without stretching which would lead to a change in sensor position and ultimately sensor calibration. A submersible cable also has a vent tube running through it to allow gauge reference pressure sensors access […]
Robust cable junction box for terminating vented electrical cable from a submersible level transmitter. vented to the outside air pressure.
There are two reference points for measuring a vacuum pressure.
