• Compound Pressure Gauge

Dual Pointer 4:1 Compound Pointer Pressure Gauge Systems

Crown Oilfield Instrumentation’s Compound Pressure Gauge systems are designed to provide a quick, accurate display of pump pressure. Dual dial is often used in pay formations where the pressures in these processes range from high to low, depending on how the formation is being treated. Main applications are for hydrostatic testing, down hole cementing operations and high pressure fracturing.  These gauges can also be used for checking pump pressures on service trucks, down hole acidizing stimulation situations, and fracturing operations.  Because this gauge has two pointers: a 360 degree sweep dial makes one full rotation while the 4:1 Vernier needle makes 4 full rotations, even the smallest pressure changes can be seen. The dampener assembly located on the top of the gauge, dampens vibrations and reduces pointer bounce so that pointers move in steady, even actions. 

The compound dual pointer pressure gauge comes equipped with two pointers and a dial that displays readings in two different PSI increments. For example, the black inner dial indicates PSI, and the yellow pointer indicates 1, 2, 3 or 4 thousand PSI. One complete sweep of the yellow pointer indicates 4000 PSI. The outer white dial indicates PSI as well; however, the max capacity is divisable by a factor of 4, and will be in 8,000, 12,000, or 16,000 PSI, depending on the application's max capacity

• Tong Torque & Tong Line Pull

Crown's tong torque and tong line pull gauges (CTT100 Series) are designed to indicate make-up or break-out torque for tool joints, drill collars, joint torque systems, and drill string components, measuring in pounds of line pull. This system is used in applications where there are two or more sets of tongs being used with differing handle lengths. A 6” fluid-filled gauge reads the pounds of line pull from the tong handle. As the joints are made-up, the line pull is converted to hydraulic pressure within the cylinder, and sent to the gauge through the rubber hose. The gauge can then display this reading in measurements of line pull. The torque being applied can be determined by multiplying the gauge reading by the foot length of the tong handle. A large variety of systems (with up to 30,000 pounds of single line pull) are available in English, Metric, or dual scale systems.
