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.

Technical Specifications

Applications

• HVAC systems (heating, ventilation, air conditioning)
• Small pump and booster systems
• Air compressor systems
• Water circulation systems
• Industrial fluid control systems
• Laboratory equipment
• Light industrial machinery

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.
