KL 1.0 100 Psi 100mm Solid Front Type Pressure Gauge Double Scale
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.

Key Advantages
Compact 40mm Design
Ideal for limited installation space and compact industrial equipment panels.
Liquid Filled Anti-Vibration Option
Glycerin or oil filling improves damping performance and reduces pointer fluctuation.
KL1.6 Industrial Accuracy
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.
