Featuring a compact 40mm dial size and a compound measuring range up to 5 Bar, this gauge is suitable for vacuum pumps, compressors, pneumatic equipment and industrial machinery. The glycerin or silicone oil filling helps dampen pointer oscillation caused by vibration and pressure pulsation, contributing to improved readability in demanding operating environments.

The compound design allows operators to monitor both negative and positive pressure conditions using a single instrument.
The liquid-filled construction helps reduce pointer flutter caused by equipment vibration and pressure pulsation, supporting clearer readings during operation.
The 40mm dial size is suitable for equipment with limited installation space while maintaining good readability.
Glycerin or silicone oil filling provides a damping effect that contributes to smoother pointer movement and easier interpretation of pressure values.
Changes in vacuum or positive pressure cause the Bourdon tube to deform elastically. This movement is transferred through an internal linkage mechanism, rotating the pointer across the dial face to indicate the corresponding compound pressure value.
A compound pressure gauge measures both vacuum and positive pressure within a single instrument.
Liquid filling helps reduce pointer oscillation caused by vibration and pressure pulsation, improving readability under dynamic conditions.
Yes. Compound pressure gauges are commonly used in vacuum pump systems where both vacuum and positive pressure indication may be required.
Glycerin and silicone oil are commonly used depending on operating temperatures and application requirements.
