    About Pressure Gauges
    industrial info icon

    Find a gauge with the right connection material and dial type—many with traceable calibration certificates.

    Gas Pressure Gauges

    Use these gauges with pumps, filters, regulators, and in process lines to monitor the pressure of compressed gas. Mount them with the dial face upright. Gauges for use with acetylene can also be used in welding applications.

    Tank-Mount Pressure-Regulating Valves for Air and Inert Gas

    These valves automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Valves have a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank.
    Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

    Single-stage valves reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank. They’re best for applications where a constant outlet pressure isn’t critical.

    Tank-Mount High-Pressure-Regulating Valves for Air and Inert Gas

    Often used for pressure-vessel testing and other high-pressure applications, these valves can handle at least seven times the outlet pressure of standard tank-mount pressure-regulating valves. They automatically reduce a high inlet pressure from compressed gas tanks to a lower, stable outlet pressure. All have Compressed Gas Association (CGA) numbered inlet fittings for secure connections to compressed gas tanks. Choose a valve with the same CGA number as your tank and other system components. Outlet fittings are Swagelok® for a leak-free seal around hard metal tubing in high-pressure lines. Also known as instrumentation fittings, Swagelok® fittings are compatible with Parker A-Lok, Gyrolok, Bilok, and Tylok fittings. Valves have a gauge to monitor outlet pressure and a gauge to monitor inlet pressure from the tank. They are single stage and reduce pressure in one step, which causes the outlet pressure to fluctuate slightly as you empty the tank.
    Choose a valve with a maximum outlet pressure that’s approximately twice your application’s normal operating pressure. Your operating pressure should never exceed 75% of the valve’s maximum outlet pressure.

    Pressure Transmitters for Oxygen

    Adhere to safety standards and monitor pressure when working with high concentrations of oxygen. These transmitters are cleaned following ASME B40.100 IV guidelines and are sealed in an airtight bag to prevent contamination before use. Also known as transducers, they convert pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls. For your receiving device to interpret the signal from the transmitter, you will need to calibrate it for the transmitter's pressure range and output signal. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.
    These transmitters are rated NEMA 4X and IP65 for protection from dust, weather, washdown, and corrosion. UL and C-UL recognized components and CE marked, they also meet American, Canadian, and European safety standards.
    With an output current, they connect using two wires. The same wire is used to send a signal to the receiver and to power the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices.
