-30 CmHg Low Pressure Gauge 316 SS Bellows Manometer Radial Mount

Product Introduction

With a measuring range of -30~0 cmHg and a 63mm dial size, the gauge is ideal for laboratory equipment, medical devices, environmental monitoring systems, filter monitoring, cleanroom applications, and industrial process control where conventional Bourdon tube gauges cannot provide sufficient sensitivity.

The SUS316 pressure element offers excellent corrosion resistance, while the capsule mechanism enables accurate low-pressure measurement and full vacuum operation. The gauge is designed with 10-times overpressure protection and front zero adjustment for enhanced reliability and long-term performance.

Technical Specifications

Working Principle

Unlike standard Bourdon tube gauges, capsule pressure gauges utilize two thin-walled diaphragms welded together to form a pressure-sensitive capsule element. When low pressure or vacuum is applied, the capsule expands or contracts in proportion to the pressure variation.

The movement is mechanically transmitted to the pointer through a precision gear mechanism, providing highly sensitive and accurate indication of low pressure and vacuum values.

This measuring principle allows accurate monitoring of pressure levels that are too small for conventional pressure gauges to measure effectively.
