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.

Technical Specifications

Applications

• HVAC systems (heating, ventilation, air conditioning)
• Small pump systems and booster units
• Air compressor systems
• Water circulation systems
• Laboratory and testing equipment
• Food processing machinery
• Light industrial automation systems

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.
