5 Bar Dry Pressure Gauge KL1.6 Liquid Filled Oil Pressure Gauge 40mm
KL1.6 40mm Liquid Filled Pressure Gauge 0–5 Bar Dry Type EN 837-1 Compact Manometer
Product Overview
The KL1.6 40mm pressure gauge is designed for low-pressure industrial applications ranging from 0 to 5 bar. It features a compact structure with optional liquid-filled (glycerin/oil) or dry-type configuration, ensuring flexibility for different working environments.
Built with a Bourdon tube sensing element and manufactured according to EN 837-1 standard, this gauge delivers stable mechanical pressure readings without electrical power.
The liquid-filled version improves vibration resistance and reading stability in pump systems, HVAC units, and small industrial machinery.

Key Advantages
Compact 40mm Design
Ideal for space-limited installations and compact machinery panels.
Liquid Filled Anti-Vibration Option
Glycerin or oil filling reduces vibration and improves pointer stability.
KL1.6 Industrial Accuracy
Suitable for general industrial low-pressure monitoring applications.
Dry and Filled Dual Structure
Flexible configuration based on environmental and system requirements.
EN 837-1 Standard Compliance
Ensures international compatibility and measurement reliability.
Working Principle
The Bourdon tube deforms under pressure changes. This mechanical movement is transferred through a linkage system to drive the pointer. The scale displays real-time pressure values without requiring electricity.
Liquid filling reduces internal vibration and damping improves reading stability in dynamic systems.
