High-Clarity Vibration-Resistant Pressure Gauges
These gauges have a unique case design that eliminates the air bubble on the dial face, which can distort readings. The liquid in the dial reduces needle flutter for precise readings in high-vibration applications. Use them in pumps, filters, regulators, and in process lines to measure and display pressure. Mount gauges with the dial face upright.
Gauges with an internal seal resist clogging and corrosion.

Maximum-Indicating Vibration-Resistant Pressure Gauges
These gauges have a red needle that indicates the highest pressure reached since the last setting. They have a glycerin-filled dial that reduces needle flutter for precise readings in high-vibration applications. Use them with pumps, filters, regulators, and in process lines to measure and display pressure. Mount gauges with the dial face upright.

Remotely monitor pressure in general purpose applications such as pumping and compressing systems. These transmitters, also known as transducers, 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.
Transmitters with current output 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.
Transmitters with voltage output connect using three wires—two wires into the power supply and a separate wire that sends a signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.
Transmitters with calibration certificate traceable to NIST include documentation that states they've passed a test for accuracy.
Transmitters are rated NEMA 4X and IP65 or IP67 and are good for washdown and corrosive environments.
Transmitters with a micro M12 plug connection are compatible with micro M12 connectors.

At least four times as accurate as standard pressure transmitters, these transmitters are ideal for use in laboratories and analytical testing applications. All come with a calibration certificate traceable to NIST that states they’ve passed a test for accuracy. Also known as transducers, pressure transmitters convert pressure to an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers, and motor speed controls to monitor pressure or control equipment. As pressure increases, the output signal from the transmitter will increase. 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. Transmitters will only provide accurate readings within the rated pressure range.
These transmitters connect using two wires to send a 4-20mA current output. 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.
All transmitters are CE marked, meaning they meet European safety standards. NEMA 4X rated transmitters are for use in washdown and corrosive environments. IP67 rated transmitters are protected from temporary submersion during washdowns.

Choose these transmitters when you need reliable pressure monitoring but not high accuracy. 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.
Rated IP65, all seal out dust and water from light rinses. They’re CE marked, so they meet European safety standards.

Fine-tune the pressure range on these transmitters to account for changes in pressure readings over time. With an adjustable range, also known as adjustable zero and adjustable span, the top and bottom of the pressure range can be changed by up to 5%. This saves you from having to make corrections on receiving devices, such as programmable logic controllers (PLCs), remote displays, and motor speed controls. These transmitters, often called transducers, convert pressure to an electrical signal that is interpreted by receiving devices to monitor pressure or control equipment. As pressure increases, the output signal from the transmitter will increase. Transmitters will only provide accurate readings within the rated pressure range.
Rated NEMA 4X, these transmitters stand up to washdowns and corrosion.

Tank-Mount High-Pressure-Regulating Valves for Air and Inert Gas
- For Use With: See Table
- Temperature Range: -20° to 120° F
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.
