Pressure Gauge Pressure gauges are mechanical instruments that are often read manually and are rather affordable. A thin-walled metal tube that is normally threaded into the compartment where pressure is being monitored is part of Bourdon gauges. The tube starts to straighten as the pressure inside it rises. A lever system with a pointer is on the tube's other end. The pointer rotates around a dial, displaying pressure in pounds per square inch, as the tube straightens (PSI). Curved or C-shaped, spiral, and helical tubes are typical tube shapes. This mechanical instrument must be manually read. A diaphragm gauge is a different class of mechanical gauge that performs similarly and also has a pointer. Temperature and pressure recorder-receiver An device developed for general temperature and pressure applications, a temperature and pressure recorder-receiver records controlled temperature and pressure on a graph. A helical Bourdon tube coupled to a piping system makes up the static pressure system, which measures static pressure. A spiral Bourdon tube, a capillary, and a bulb make up the thermal system. Typically, stainless steel is used for all parts. Frequently, a pen system that continuously records data serves as the recording mechanism. The pressure and temperature mechanical input are transformed into lines on a revolving chart. Hydrostatic Test Pumps A hydrostatic test pump is a self-contained, portable, low volume, high pressure pump with a high pressure hose attached to the apparatus and power sources including manual, air, electric, or gas engines. In order to test a component, a pump is utilized to fill it with an incompressible liquid, usually water. The pressure of the test component is gradually increased to a predefined set point and kept for a predetermined period of time with the assistance of the pump that incorporates necessary safety relief and controls. The pressure is then checked visually to see whether there are any leaks or if it has dropped below the preset pressure. This hydrostatic pressure test equipment is compact, efficient and cost effective, available in different combinations of pressure and flow (pressures to 1000 bar (14,500 psi) are possible). Though theoretically water is considered as non compressible fluid, it requires considerable amount of feeding to raise the pressure.
