Hydraulic All Stainless Steel Liquid Filled Hydraulic Pressure Gauge Heavy Duty for High Pressure Monitoring
KL1.6 40mm Pressure Gauge 0–5 Bar Liquid Filled / Dry Type EN 837-1 Industrial Manometer
Product Overview
The KL1.6 40mm pressure gauge is a compact industrial measuring instrument designed for low-pressure applications ranging from 0 to 5 bar. It is available in both dry and liquid-filled (glycerin or oil filled) configurations to meet different working environments.
Built with a Bourdon tube sensing element and manufactured according to EN 837-1 standard, this gauge ensures reliable mechanical pressure measurement without external power.
The liquid-filled version improves vibration resistance and provides stable readings in pump systems, HVAC equipment, and industrial fluid control applications.

Key Advantages
Compact 40mm Design
Ideal for small installation spaces and compact equipment panels.
Liquid Filled Anti-Vibration Structure
Glycerin or oil filling reduces vibration and improves pointer stability.
KL1.6 Industrial Accuracy
Suitable for general industrial low-pressure measurement systems.
Dual Structure: Dry / Filled Type
Flexible configuration for different working conditions.
EN 837-1 Standard Compliance
Ensures international reliability and industrial compatibility.
Working Principle
The Bourdon tube deforms when pressure is applied. This mechanical movement is transmitted through a linkage system to rotate the pointer and display pressure values.
Liquid filling dampens internal vibration and prevents pointer oscillation under pulsating pressure conditions.
