Pressure Gauges

Bourdon Tube Gauges
Mechanical dial gauges using a curved, flattened tube that straightens under pressure to move the pointer. They are the most common general-purpose gauge for medium-to-high pressures on pumps, manifolds, and process lines.
Diaphragm Gauges
Gauges that sense pressure with a flexible diaphragm rather than a Bourdon tube, suited to low pressures and to corrosive, viscous, or solids-laden media such as mud and slurries where the diaphragm isolates the mechanism.
Differential Pressure Gauges
Instruments that measure the difference between two pressure connections, used for filter and strainer monitoring, flow across orifices, and level measurement in vessels.
Electronic Pressure Gauges
Digital gauges with strain-gauge, sapphire, or piezoresistive sensors and a digital display or output signal, offering higher resolution, data logging, and remote transmission compared with analog dials.
Wireless Pressure Gauges
Battery-powered electronic gauges that transmit readings over a radio link, allowing remote monitoring of wellheads, treating iron, and frac sites without cabling.
Permanent Downhole Gauges
Pressure and temperature sensors deployed on the completion string and cabled to surface for continuous, long-term reservoir and well surveillance throughout the producing life of the well.
Quartz and Sapphire Downhole Gauges
High-accuracy, high-stability downhole sensors using a quartz-crystal or sapphire sensing element for precise bottomhole pressure measurement in reservoir testing and permanent monitoring at elevated temperatures.
High-Pressure / High-Temperature Gauges
Gauges rated for severe service such as frac and well-test pressures and geothermal or deep-well temperatures, built with reinforced sensing elements and connections like the 1502 hammer union.
