KL1.6 40mm Liquid Filled Pressure Gauge 0–5 Bar Dry Type EN 837-1 Compact Industrial Pressure Gauge

Product Overview

The KL1.6 40mm pressure gauge is a compact industrial instrument designed for low-pressure measurement systems from 0 to 5 bar. It supports both dry and liquid-filled (glycerin/oil) configurations to meet different operating environments.

This gauge uses a Bourdon tube mechanical sensing element, providing stable and reliable pressure readings without electrical power. It is widely used in HVAC systems, pump equipment, compressors, and light industrial machinery.

The liquid-filled version significantly improves vibration resistance and reduces pointer fluctuation under pulsating pressure conditions.

Suitable for general industrial low-pressure measurement applications.

Dry and Filled Dual Structure

Flexible configuration based on different working environments.

EN 837-1 Standard Compliance

Ensures international reliability and interchangeability in global markets.

Working Principle

::contentReference[oaicite:0]{index=0}

The Bourdon tube inside the gauge deforms under pressure. This mechanical movement is transferred through a linkage system to rotate the pointer and display pressure values.

Liquid filling reduces vibration impact and stabilizes the pointer in dynamic pressure systems.
