Bellows bellows pressure gauges used as a measurement of tiny pressure sensitive element.Measure the corrode the copper alloy, no explosion danger the micro pressure and negative pressure of the gas, widely used in boiler ventilation, gas pipeline, burning device and other similar devices.
Principle of bellows pressure gauge:
Instrument (including joint bellows, etc.) by measuring system, transmission mechanism, an indicating device and the shell.
When the measured medium pressure acting on the bellows, the free end displacement of the corresponding elastic deformation, the shifter lever to drive actuator amplifier, by indicating device will be measured out pressure on the dashboard instructions.
Bellows pressure gauge main technical indicators:
Scale range, accuracy grades, and weight
