50mm Vacuum Capsule Pressure Gauge Steel Case Brass Internals

Product Introduction

The 50mm vacuum capsule pressure gauge is designed for measuring low pressure and vacuum conditions involving dry and non-corrosive gaseous media. The brass capsule sensing element provides sensitive response to small pressure variations commonly found in medical, laboratory and environmental monitoring applications.

Featuring a black steel case, brass internals and front zero adjustment, this mechanical vacuum gauge delivers reliable indication without requiring an external power source. Typical applications include vacuum ovens, suction regulators, respirators and filter monitoring systems.

Product Advantages

1. Sensitive Vacuum Measurement

The brass capsule sensing element responds effectively to small pressure changes encountered in vacuum applications.

2. Compact Design

The 50 mm dial size is suitable for installations with limited panel space.

3. Reliable Mechanical Indication

Provides pressure monitoring without external electrical power requirements.

4. Convenient Zero Adjustment

Front adjustment simplifies routine inspection and calibration procedures.

Working Principle

The capsule element consists of joined diaphragms forming a pressure-sensitive chamber. Changes in vacuum pressure cause the capsule to deflect, transmitting movement through the gauge mechanism to indicate the measured value on the dial.

How to Select a Vacuum Capsule Pressure Gauge

• Select a measuring range appropriate for the operating vacuum level.
• Verify compatibility with dry gaseous media.
• Choose a dial size suitable for visibility requirements.
• Confirm mounting configuration before installation.
