Monitor hydraulic fluid or oil level in pressurized applications.

These flexible indicators bend to follow the contours of a tank.

Avoid overfilling—these indicators pop up when your tank is almost full.

Mount these indicators from the inside of your tank through unthreaded holes.

Simultaneously monitor hydraulic fluid or oil level and temperature in gear boxes, crank cases, and other reservoirs.

Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators are also known as armored level gauges.

Machined from one piece of stain- and impact-resistant plastic.

The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window.

With a thick glass window fused to a metal body, these sights resist cracking at high pressures.

Press these sights into a hole in your tank wall; no additional mounting nuts are needed. They mount from the outside.

Fasten the extended flange to tank walls.

For use with water, hydraulic fluid, and diesel, install these gauges through the top of your tank.

These gauges fit into square cutouts in your instrument panel.

A digital display allows for easy reading of measurements.

Gauges come in a variety of colors so you can identify an important spot in your process line.

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. They have a digital display for easy reading of measurements.

A liquid-filled dial reduces needle flutter for precise readings in high-vibration applications.

These gauges have a red needle that indicates the highest pressure reached since the last setting. They have a liquid-filled dial that reduces needle flutter for precise readings in high-vibration applications.

Gauges have an accuracy of ± 2%.

Gauges have an accuracy of ± 0.5% to ± 1%. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications.

Gauges have an accuracy of ± 1% to ± 1.5%. They are suitable for critical processes that require high accuracy, such as hydraulic and laboratory applications.

Use in high-pressure applications up to 2,000 psi.

These gauges have a liquid-filled dial that reduces needle flutter in high-vibration applications reaching 2,000 psi.

Sensitive enough to operate on indoor light, these gauges have no batteries to replace. Gauges have a digital display for easy reading of measurements.

Use in medium-pressure applications up to 1,500 psi.

Keeping corrosive substances from touching pressure gauges used in food-processing and pharmaceutical plants, these guards have a sanitary design.

Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure.

At least four times as accurate as standard vacuum transmitters, these transmitters sense vacuum at an accuracy of ±0.25%, making them ideal for use in laboratories and in analytical testing applications.

Monitor and control equipment in food-processing and pharmaceutical plants—these transmitters convert vacuum into electrical signals for receiving devices and have a 3-A certified sanitary design. They automatically compensate for vibration and temperature changes, saving you the effort of programming manual corrections.

Remotely track your system's pressure readings from the convenience of a smartphone or tablet. Good for preventative maintenance and route-based monitoring, these battery-powered transmitters use Bluetooth to alert you when equipment requires your attention.

For use in wet environments, these transmitters are rated NEMA 4X for protection from washdowns and corrosion.

Monitor and control pressure in portable HVAC systems, hydraulics, and oil and gas equipment. Unlike other pressure transmitters that measure the difference between your system and the atmosphere, these transmitters give measurements relative to zero pressure—regardless of altitude or temperature.

These transmitters automatically compensate for error introduced by vibration as well as temperature fluctuations, so you do not need to program your receiving device to correct for these factors. 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 to monitor pressure or control equipment.

Used in food-processing and pharmaceutical plants to automatically compensate for temperature changes and errors caused by vibration, these transmitters have a sanitary design certified by 3-A.

With an accuracy of ±0.25%, use these transmitters in applications that require highly accurate measurement of both pressure and vacuum, such as activating vacuum pumps.

These transmitters automatically compensate for error introduced into both pressure and vacuum measurements by vibrations as well as temperature fluctuations, so you do not need to program corrections for these factors into your receiving device. They convert pressure and vacuum 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.

Used in hazardous locations, these transmitters safely convert pressure and vacuum into an electrical signal to measure liquids, gases, and steam. NEC rated for safety, these transmitters are explosion proof, so they can be used in environments containing flammable gases and vapors.

Measure the difference in pressure between two points in flow applications, such as heating, cooling, and pumping systems.
