Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure. They are commonly used to indicate clogged filters.

Magnet-mount gauges can be moved for use in multiple locations. Gauges with barbed tube connection have a flexible body that rolls up for storage or transport.

Measure small changes in air pressure with these hand-held gauges. They have a four-digit LCD display for easy reading of measurements. Gauges are commonly used to indicate clogged filters and to monitor fans and blowers.

Easier to read than U-tube gauges, these use an inclined scale to measure pressure or velocity in air applications. Gauges are also known as manometers.

Gauges have a four-digit LCD display for easy reading of measurements. Commonly used to indicate clogged filters, these gauges display the difference between two pressure or vacuum measurements. They are also known as compound gauges.

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. They’re also rated IP66 and NEMA 4X to withstand dust and washdowns. To prevent bacteria growth, as well as make cleaning easier, they have polished surfaces and continuously-welded seams. Their housing is 304 stainless steel to resist harsh cleaners and sanitizers. Connect them to your line using gaskets and clamps to join them to sanitary quick-clamp fittings (often called tri-clamp fittings); they’re easy to attach and remove for cleaning.

With these transmitters, there’s no need to program corrections for vibration and temperature fluctuations into your receiving device. Set the pressure range, choose the unit of measure, and zero the reading using the digital keypad. These transmitters convert pressure into an electrical signal that receiving devices, such as remote displays, programmable logic controllers, and motor speed controls, use to monitor pressure and control equipment. They will only provide accurate readings within the rated pressure range. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. Transmitters are also known as transducers.

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.

Choose transmitters with a sensor cable to monitor pressure, set the pressure range, choose the unit of measure, and zero the reading from a distance.

These transmitters are commonly used to monitor airflow and to indicate when filters in HVAC systems become clogged. They convert the difference in pressure between two points in a low-pressure system into 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. Transmitters will only provide accurate readings within the rated pressure range. They come with a calibration certificate traceable to NIST. Maximum pressure is the maximum spike in pressure a transmitter can withstand without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. All transmitters are rated IP67 for protection in washdown environments.

These transmitters connect using three wires—two wires into the power supply and a separate wire that sends a voltage signal to the receiver. The receiver and the transmitter share a common ground wire back to the power supply.

For use in hazardous locations, these transmitters safely measure the difference in pressure between two process lines in flow applications—such as heat exchangers, chillers, and pumps. They meet NEC safety standards, so they protect against an explosion where flammable gases and vapors are present.

Automatically compensating for error from temperature fluctuations or vibration, these transmitters don’t require additional programming into your receiving device to correct these factors. Set the pressure range with the keypad, select the unit of measure, and zero the transmitter. They convert differential pressure into an electrical signal that can be interpreted by receiving devices, such as remote displays, programmable logic controllers (PLCs), and motor speed controls, to monitor pressure or control equipment. Transmitters will only provide accurate readings within the rated pressure range. Maximum pressure is the greatest spike in pressure a transmitter can tolerate without damage. Transmitters are accurate only within the pressure range, not up to the maximum pressure. Rated IP66 and NEMA 4X, they protect against dirt, dust, corrosion, weather, and washdowns, and the hastelloy connection protects against harsh chemicals.

Most often, these transmitters connect using two wires to send a 4-20mA current output. The same wire that sends a signal to the receiver also powers the transmitter. Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. Three- and four-wire configurations are also possible.

Current doesn’t lose signal over long distances and isn’t affected by electrical interference from other devices. They can also be configured using three or four wires.

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. They’re rated IP66 and NEMA 4X for protection from dust and water jets, and made of 316 stainless steel, so they won’t corrode from frequent washdowns with harsh cleaners. A highly polished surface and continuously welded seams leave no crevices for bacteria to grow. They connect to sanitary quick-clamp fittings—also known as tri-clamp fittings—that are easily assembled for regular cleaning.

Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on a display. With two outputs, these transmitters—also known as transducers—can be used as a transmitter, a switch, or both. All send electrical signals to your programmable logic controllers to trigger actions in your system. You can even use an IO-Link controller (not included) to connect them to a programmable logic controller or human-machine interface to change settings and receive messages remotely. For your receiving device to interpret the signal from these transmitters, you will need to calibrate them for the transmitters’ pressure range and output signal. As pressure increases, the output signal from the transmitters will increase. Transmitters will only give accurate readings within the rated pressure range.

The transmitters’ display has buttons to easily adjust set points, measuring range, scales, and other settings. The approximate difference between the set point and the reset point is adjustable, so you can set it anywhere within the set point range. Program the display to show red and green colors to signal the status of your process. Two LEDs alert you to the switching status of your output. The display head rotates 345° for the best view.

These transmitters have a 316L stainless steel connection to stand up to corrosion. All are rated IP65 and IP67, so they are protected against dust, low-pressure jets of water, and temporary submersion. They also meet U.S., Canadian, and European safety standards.

All of these transmitters have an M12 plug connection and are for use with M12 sockets. For their 4-20mA output current range, they’ll need a two-wire connection. When using both switching outputs and an IO-Link controller, they’ll require a four-wire connection. To view transmitter wiring diagrams, select a part number and click Product Detail.
