Q1: Can a bellows pressure gauge measure liquid media?
A: Mainly designed for gas micropressure and llow-pressuremeasurement. It is generally not recommended to measure liquids, as they can easily enter the interior of the membrane box and cause corrosion and zero drift; Spring tube, diaphragm, or diaphragm pressure gauges are preferred for measuring liquids.
Q2: What is the difference between stainless steel bellows and ordinary bellows pressure gauges?
A: Ordinary membrane box overcurrent components are mostly made of copper alloy and can only be used for dry and non-corrosive gases; The overcurrent components of the stainless steel membrane box are made of stainless steel and can be used in weakly corrosive gases and humid conditions, with stronger corrosion resistance.
Q3: Can it withstand high voltage?
A: Not suitable for high pressure; the range is mostly for micro pressure and low pressure. Overpressure can cause permanent deformation of the membrane box, zero offset, and measurement failure; Please use a spring tube pressure gauge for high-pressure conditions.
Q4: What is the reason for the occurrence of zero point not returning to zero?
A: Most of them are caused by overpressure overload, pressure shock, and corrosion of the medium film box. Do not use it beyond its range, and use stainless steel for corrosive gases. If there is a zero offset, recalibration is required. If the damage is severe, replace the instrument directly.
