Low Pressure Capsule Gauges overview

Capsule pressure gauge is sensitive instruments used in low pressure measurement typically not exceeding 60kPa. It is used in a wide range of applications including medical, heating, gas pipe-lines, burners，air-conditioner and many others. The standard low-pressure capsule gauges are designed to measure the low pressure of gas that does not corrode the copper alloy. This low pressure gauge series features a copper alloy capsule and socket. Low Pressure Gauge is suitable for accurate measuring the low pressure of corrosive gas or fluid in corrosive environment. This capsule pressure gauge series also features a SUS 316 capsule and socket. Low pressure gauge kpa can be used as panel mount air pressure gauge, natural gas pressure gauge, low pressure air gauge Low pressure water gauge, air compressor pressure gauge.,etc. As a China Pressure Gauge factory, we can provide cheap price pressure gauge also with excellent quality, and another advantage of our pressure gauge manufacturer is that we have fast delivery time even with custom capsule pressure gauge.

How the Capsule Pressure Gauge Works

Low range pressure gauge uses the diaphragm capsule as the sensing element for low pressure measurement. The diaphragm capsule is an elastic metal sensing element comprised of two thin wall diaphragms whose sides are soldered together to the capsule. Whenever air，gas enters the intake port (gauge connection),Kpa vacuum gauge travels into the diaphragm capsule. The walls of the capsule expand and contract in response to the change in pressure. This change is then transferred to a rotating rod of low pressure air gauge and arm that rest on the outside of the capsule of low range pressure gauge. The rotating rod of low pressure gauge kpa is connected to a geared movement through a linkage system. Connected to a shaft，this system then drives the pointer pressure gauge over a dial marked in appropriate pressure or vacuum units to provide a pressure reading.
