Gauges are used in most areas of manufacturing. Coast Pneumatics gauges are especially suited for applications in pneumatics, hydraulics, process, petrochemical, medical, food, pharmaceutical and a majority of industrial and commercial applications. Our line of gauges consist of high-quality dry gauges, designed to provide reliable service. All cases are made of plastic. The crystals are clear-front plastic. The high quality bourdon tubes are made in the "C" configuration. The precision movements provide accurate readings with a maximum of plus or minus 2.5% of full scale tolerance.>

Bourdon Tube Gauges are the most commonly used of all pressure gauges. They are used almost exclusively for measurements in industrial hydraulic and pneumatic systems, where pressure above 15 PSI are expected. Accuracy of Bourdon Tube gauges is good to excellent, dynamic response is fair and static response is excellent. The main working element in the gauge is a tube (a Bourdon tube) shaped like a letter "C". As the pressurized fluid enters this tube, it tends to straighten it, moving the tube tip. The movement displaces a connecting linkage that actuates a pointer on the gauge face.

Differential-pressure gauges are available in Bourdon tube mechanisms. Typically, they have two independent measuring chambers, each connected to a different pressure source. However, they have only one pointer which shows the pressure difference between the two gauges. >
