Technical Specifications

Working Principle

The pressure gauge operates using a Bourdon tube measuring element. When pressure enters the gauge through the G1/4 connection, the Bourdon tube deforms proportionally to the applied pressure.

1. Pressure enters the measuring element.
2. The Bourdon tube expands slightly under pressure.
3. The movement is transmitted through a precision linkage mechanism.
4. The pointer rotates across the calibrated dial scale.
5. The pressure value is displayed instantly and continuously.

The glycerin filling absorbs vibration and pressure pulsation, helping maintain smooth pointer movement and improving reading accuracy in dynamic operating environments.

FAQ

Why is glycerin used inside pressure gauges?

Glycerin dampens vibration and pressure pulsation while protecting internal components.

Can this gauge be used for hydraulic systems?

Yes. The 0-40MPa range is specifically suitable for hydraulic pumps, power units, and fluid power systems.

What does radial mount mean?

Radial mount means the pressure connection is located at the bottom of the gauge.

What is the benefit of a 63mm dial?

It provides a balance between readability and compact installation size.
