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.

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.
KL1.6 indicates ±1.6% full-scale accuracy for industrial pressure monitoring.
To reduce vibration and improve reading stability in pump and compressor systems.
It is designed for compact installations where space is limited.
It defines international standards for mechanical pressure gauges.
