The glycerin-filled construction helps dampen pointer movement caused by vibration and pulsating conditions, supporting clearer pressure indication. Liquid-filled gauges are commonly used in environments with high vibration levels.
2. Compact Design for Limited Installation Space
The 40mm dial size allows installation in compact equipment and control panels where space is restricted.
The center back connection design simplifies integration into equipment panels and enclosed systems.
The Bourdon tube mechanism provides direct vacuum indication without batteries or electrical components. Bourdon tubes remain one of the most widely used technologies for vacuum measurement.
Designed for non-corrosive gaseous media commonly encountered in vacuum pumps, pneumatic equipment and filtration systems.
When vacuum pressure is applied to the Bourdon tube, the sensing element deforms elastically relative to atmospheric pressure. The movement generated is transferred through an internal linkage mechanism, causing the pointer to rotate and indicate the corresponding vacuum value on the dial.
A negative pressure gauge measures pressure below atmospheric pressure and is commonly referred to as a vacuum gauge.
Glycerin filling helps reduce pointer flutter caused by vibration, improving readability and helping protect internal components.
Yes. This type of gauge is widely used for vacuum pump monitoring applications.
No. This model is designed specifically for vacuum measurement within a range of -0.1 MPa to 0 MPa.
