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

Absolute Reference Pressure Range
Referenced to absolute zero pressure or a perfect vacuum
- a
- A
- abs
- ABS

Special options for ATEX , SIL2 and compound ranges.
Differential Pressure Range
The difference in pressure at point B compared to the pressure at point A.
- d
- D
- diff
- DIFF
- dp
- DP

PrimAtü 10 Low Cost Low Range Differential Air Pressure Transducer - The PrimAtü 10 low cost low range differential air pressure transducer can detect and display both positive and negative differential pressure variations of very low low pressure ranges from 0.5 up to 1000 mbar/hPa, and output the pressure as a 4-20mA, 0-20mA or a 0-10Vdc analog output.
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.
