40mm Axial Liquid Filled Pressure Gauge 0-25MPa Class 1.5 | 3500 PSI High Pressure Monitoring Gauge

Product Overview

The 40mm Axial Liquid Filled Pressure Gauge is engineered for precise pressure monitoring in hydraulic systems, industrial machinery, compressors, testing equipment, and fluid control applications. Featuring a compact 40mm (1.5-inch) dial, rear axial connection, and liquid-filled construction, this gauge provides stable and reliable readings even under severe vibration and pressure pulsation conditions.

Technical Specifications

Key Features

Compact 40mm Design

The 40mm dial size allows installation in limited-space equipment, compact machinery panels, and OEM systems.

High Pressure Measurement Capability

Suitable for applications requiring pressure monitoring up to 25MPa (250 Bar / 3500 PSI).

Class 1.5 Accuracy

Provides reliable pressure indication for industrial monitoring and process control.

Axial Mount Configuration

Rear connection design simplifies panel installation and improves gauge visibility.

Working Principle

This pressure gauge operates using a Bourdon tube sensing element. When pressure enters the tube, it elastically deforms in proportion to the applied pressure.

The resulting mechanical movement is transmitted through a precision gear mechanism, causing the pointer to rotate across the calibrated scale and display the pressure value.

The liquid-filled chamber absorbs vibration and sudden pressure fluctuations, resulting in improved pointer stability and measurement reliability.

FAQ

What does Class 1.5 accuracy mean?

Class 1.5 indicates that the measurement error does not exceed ±1.5% of the full-scale range.

Can this gauge be used in hydraulic systems?

Yes. The 25MPa pressure range makes it suitable for many hydraulic and fluid power applications.

Why choose a 40mm pressure gauge?

The compact size is ideal for installations where available panel or equipment space is limited.

What is an axial mount pressure gauge?

An axial mount gauge features a rear connection that allows installation through equipment panels or enclosures.
