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.
To help identify the reference of a particular pressure range found on a product label or technical data sheet a list of abbreviated suffixes is provided below.
Vented Gauge Reference Pressure Range
Measuring pressure with reference to atmospheric pressure, also referred to as Relative and Vented Gauge:
- g
- G
- rel
- REL
- vg
- VG

KL1 Cable Junction Box for Submersible Level Transmitters - Robust cable junction box for terminating vented electrical cable from a submersible level transmitter. vented to the outside air pressure.
Recordable indicator and sensor up to 30000 psi for pressure test rig - Accurate and reliable pressure measurement up to 30,000 psi with integrated data recording. Ideal for demanding pressure test rig applications.
Sealed Gauge Reference Pressure Range
Not vented to atmospheric pressure, but instead the reference is fixed to 1 bar.
- sg
- SG

UPS-HSR USB Pressure Sensor with High Sample Rate Logging - USB ready digital pressure sensor for recording pressures with a high speed sample rate of up to 1 kHz to a computer.
SSPT Subsea Wet-Mateable Electrical Connector Pressure Sensor - This stainless steel ceramic sensing diaphragm based subsea connector pressure sensor provides a unamplified ratiometric millivolt output or an amplified analogue output signal corresponding to ranges from 0…1 bar (14.50 psi) up to 400 bar ( 5800 psi).
Absolute Reference Pressure Range
Referenced to absolute zero pressure or a perfect vacuum
- a
- A
- abs
- ABS
Featured absolute reference related products
Manufacturing automation absolute pressure sensor with 100psia range and 0-10Vdc out - This absolute pressure sensor offers precise and reliable pressure measurement for pneumatic systems. With its 0-10Vdc output, it seamlessly integrates with industrial control systems.
DMP320 0.5 msec Fast Response Pressure Sensor - High frequency response pressure sensor with a better than 0.5 millisecond response time and internal digital signal conditioning that samples readings at a rate of 10 kilohertz.
Differential Pressure Range
The difference in pressure at point B compared to the pressure at point A.
- d
- D
- diff
- DIFF
- dp
- DP
Featured differential pressure related products
DPS300 User Switchable Pressure Range, Volts or Current Output Low DP Sensor - The DPS 300 is a low range HVAC differential pressure sensor. The lowest possible pressure range is 0...100 pascals. 2 or 3 switchable pressure ranges, plus volts or current output are included with most standard configurations.
Intrinsically Safe DP Sensors - Intrinsically safe differential pressure sensors are essential for accurate pressure measurement in hazardous environments where explosive atmospheres may be present.
On product marking labels or any document that includes a description of the pressure range, the reference type is included after the pressure unit type e.g. 15 psi abs or 15 psia.
