Product overview
Capsule gauges are sensitive instruments used in low pressure applications typically not
exceeding 100kPa.It is used in a wide range of applications including medical,heating,gas
pipe-lines,burners,air-conditioner and many other industrial fields.The standard
low-pressure capsule gauges are designed to measure the low pressure of gas that does not
corrode the copper alloy.
Features
◇Available from Φ50、Φ65、Φ75、Φ100with different mountings
◇2 styles:Screw in organic glass;Screw fastening window
◇Positive,negative,compound pressure ranges,minimum range is 5kPa~100kPa
◇A variety of options
How the Capsule Gauge Works
Capsule gauges use the diaphragm capsule as the sensing element for pressure
measurement.The walls of the capsule expand and contract in response to the change in
pressure.This change is then transferred to a rotating rod and arm that rest on the outside of
the capsule.The rotating rod is connected to a geared movement through a linkage
system.Connected to a shaft,this system then drives the pointer over a dial marked in
appropriate pressure or vacuum units to provide a pressure reading.
