    Pressure gauge dimensions


    Q1: What is a pressure gauge?
    A1: A pressure gauge refers to an instrument that uses elastic elements as sensitive elements to measure and indicate pressure higher than the environment. It is used in almost all industrial processes and scientific research fields, mainly in heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicle maintenance. Maintenance shop, etc. Especially in the process of industrial process control and technical measurement, mechanical pressure gauges are becoming more and more popular due to the high mechanical strength and convenient production of the elastic sensitive components of mechanical pressure gauges.

    Q2: How does a pressure gauge work?
    A2: The pressure gauge transmits the pressure deformation to the pointer through the elastic deformation of the sensitive components (Bourdon tube, diaphragm box, bellows) in the watch, and then the conversion mechanism of the watch movement, causing the pointer to rotate to display the pressure. This is the working principle of a pressure gauge.

    Q3: What is a pressure gauge used for?
    A3: sisco pressure gauges are both air pressure gauges and water pressure gauges and are mainly used for pressure detection in metallurgy, electric power, petroleum, chemical industry, light industry, machinery, etc. The pressure gauge relies on measures such as internal filling of damping oil and matching buffer devices, and has good shock resistance. It is suitable for occasions where the pressure of the measured medium has strong pulse changes or pressure shocks, and often suddenly unloads in the production process, as well as environmental vibrations. The pressure gauge can measure the average value of the pulsating pressure of gas and liquid, so as to overcome the damage caused by the strong pulse of the medium and the vibration of the environment to ensure the accuracy of the reading.

    Tips: What do bar and psi mean on a pressure gauge?

    The bar of the pressure gauge is an imperial pressure unit, which is a unit of tire pressure, and psi is a pressure unit, which is commonly used in Europe, America and other countries. 0~300psi and 0~20bar pressure gauges are available on
