Types of Pressure Gauges According to Usage 1. Commercial and Industrial Pressure Gauges – Commercial gauges are general purpose pressure measuring instruments commonly used in Heating Ventilation Air Conditioning (HVAC) and Refrigeration. Industrial pressure gauge is suitable for production processes that would not block the pressure system. Industrial gauges are used in manufacturing industries, OEM applications, hydraulic, water treatment and RO industries. 2. Process Pressure Gauges – In industries where the production process functions under extreme conditions, subjected to vibrations, pressure spikes and a corrosive environment (like in certain areas of petrochemical and other chemical industries), a process pressure gauge can be safely used. 3. Low Pressure Gauges – These are suitable for measurement of liquid and gaseous pressure, provided they don’t obstruct its functioning. Plants construction processes, pneumatic systems and cleanrooms often need low pressure gauges. 4
