High-Accuracy Low-Pressure Gauges





Measure small pressure changes in ventilation systems, hydraulic applications, and other critical processes with these high-accuracy gauges. Mount them with the dial face upright.
Gauges with 304 stainless steel case or polyester plastic case have better corrosion resistance than gauges with steel case.
Gauges with safety case blow out in the back under excess pressure, protecting the operator in front.

Low-Pressure Differential Gauges with Dial Indicator

Measure small changes in air pressure with these gauges. They are commonly used to indicate clogged filters and to monitor fans and blowers.
Service these gauges without removing them using air filter kits. Kits include two vent valves for releasing air.
Surface mounting brackets allow gauges to be quickly installed on any flat surface. L mounting brackets can be carried to wherever you need to take a pressure reading. They can stand alone or be hung. Wraparound mounting brackets make it easy to service tubing, and don’t require cutting a hole in the wall.

Low-Pressure Differential Gauges with U-Tube
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.

Pressure and Vacuum Transmitters with Digital Display



- For Use With: Air, Argon, Diesel Fuel, Hydraulic Fluid, Nitrogen, Water
- Accuracy: ±1%
- Pipe Connection Type: Threaded
- Housing Material: Glass-Reinforced Polyester Housing
- Connection Material: 316L Stainless Steel
- Temperature Range: -10° to 175°F
Monitor and control vacuum pumps, air compressors, and hydraulics while viewing readings and warnings on the display. These transmitters, also called transducers, have two outputs, so you can program them to work as a transmitter, a switch, or both. When they reach their setpoint, they send electrical signals to your programmable logic controller (PLC) to trigger actions in your system. Adjust their reset point anywhere within the setpoint range. To change settings and receive error messages remotely from your PLC or computer, program one of the outputs to use IO Link. You need an IO-Link controller (not included) to connect to your interface.
Buttons on the display let you change your setpoint, measuring range, and other settings. To quickly tell the status of your process, you can program the color of the display to red and green. LEDs on the corners also notify you of your output’s switching status. Rotate the head to view the display from the best angle.
You must calibrate your PLC in order for it to interpret signals from these transmitters. As pressure increases, so does the output signal. These transmitters only give accurate readings within the rated pressure range.
All have an M12 plug to connect to M12 sockets. When using both switching outputs and an IO-Link controller, they require four wires to connect. For their 4-20mA analog output, they need two wires to connect. View switch wiring diagrams by selecting a part number and clicking Product Detail.
To withstand wet environments, these transmitters have a 316L stainless steel connection and are IP rated. Their IP ratings also mean they’re dust tight and stand up to spraying water and brief submersion. UL and C-UL listed as well as CE marked, they meet strict American, Canadian, and European safety standards.

Low-Pressure Differential Pressure Transmitters

- For Use With: Air, Argon, Nitrogen
- Accuracy: ±1%
- Tube Connection Type: Barbed
- Housing Material: Polycarbonate
- Temperature Range: 32° to 122° F
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.

Hazardous Location Easy-Setup Differential Pressure Transmitters

- For Use With: Air, Argon, Hydraulic Fluid, Nitrogen, Water
- Accuracy: ±0.075%
- Pipe Connection: NPT Female
- Housing Material: Aluminum
- Connection Material: Hastelloy
- Temperature Range: -40° to 185° F
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.
