63mm Radial Pressure Thermometer Gauge (Thermomanometer) 0-6 Bar 1/4" NPT EN837-1

Product Overview

The 63mm radial thermomanometer is a mechanical combined instrument designed for simultaneous pressure and temperature measurement. It uses a Bourdon tube sensing element and is manufactured according to EN 837-1 standard, ensuring stable performance in HVAC systems, water circulation systems, compressors, and general industrial pipeline monitoring applications.

This model is designed for low to medium pressure applications (0–6 bar) and is suitable for non-corrosive gas and liquid media. The radial bottom connection (1/4" NPT or BSP) allows easy installation in compact piping systems and equipment panels.

Technical Specifications

Applications

• HVAC heating and cooling systems
• Water pump circulation systems
• Air compressor pressure monitoring
• Industrial pipeline pressure measurement
• Boiler and heating systems
• Refrigeration and cooling systems
• General industrial fluid control systems

Key Advantages

1. Combined Pressure & Temperature Measurement

Integrates two measurement functions into one compact instrument, reducing installation space requirements.

2. Bourdon Tube Mechanical Structure

Provides stable and reliable operation without external power supply, suitable for industrial environments.

3. EN 837-1 Standard Compliance

Manufactured according to international pressure gauge standards for consistent measurement performance.

4. Radial 1/4" Connection Design

Ideal for compact piping systems and direct installation in equipment panels or pipelines.

5. Clear 63mm Dial Display

Easy-to-read scale ensures fast pressure and temperature monitoring during field operation.

Working Principle (Bourdon Tube)

The Bourdon tube expands and contracts under pressure changes. This mechanical deformation is transferred to the pointer, allowing direct analog pressure indication without electricity.

Installation Guide

• Use PTFE sealing tape for threaded connection
• Ensure correct radial bottom mounting orientation
• Do not exceed recommended torque during installation
• Suitable for HVAC, water, and air systems only
