Vented Gauge (VG) is a pressure referenced to atmospheric pressure via a vent path on the reverse side of the pressure sensing diaphragm.
Vented Gauge
Vented Cable
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
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 […]

50 psi g freshwater pressure transducer with 10 Vdc output signal
Freshwater compatible voltage output pressure transducer with a 50 psi gauge pressure range and a 0 to 10 volts electrical signal.
What is the difference between sealed gauge and vented gauge reference?
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.
Simulating 8000 foot altitude with a pressure gauge
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.
Recordable indicator and sensor up to 30000 psi for pressure test rig
I’m looking for a sensor and panel indicator for a pressure test rig to measure up to 30,000 psi.
Vacuum gauge to measure both absolute & negative gauge pressure
Checking vacuum pressure as a positive pressure and also as a negative pressure depending on the type of vacuum equipment being tested
Converting non-vented depth readings & barometric pressure to true depth
I have level data from a non-vented transducer & barometric pressure data, how do I determine the true depth?
Not Reading Zero when Pressure is Vented to Atmosphere
It is not unusual for a pressure measurement device to read slightly above or below zero with no pressure applied.
Using an Absolute Sensor to Measure Gauge Reference Pressure
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 […]
Determining the Signal Cable Length of a Suspended Liquid Level Transducer
Deciding the correct length of cable for a suspended IP68 transducer is an important part of specifying, if the cable is too short it is difficult and expensive to join two cables together and make the seal liquid tight. There are two separate parts of the installation that need to be considered to determine the […]
What does the suffix a, abs, d, dp and diff, g, rel and sg mean after the pressure units in a pressure range?
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.
What is the difference between gauge and absolute pressure measurement
Determining whether you need gauge or absolute reference pressure is a very important to selecting the right pressure range for a pressure instrumentation.
Improve the electrical termination of vented submersible pressure sensors
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 […]
