Vibration-Resistant Pressure Gauges
A liquid-filled dial reduces needle flutter for precise readings in high-vibration applications. Gauges are commonly used with pumps, filters, regulators, and in process lines to measure and display pressure. Mount them with the dial face upright.
Gauges with 304 stainless steel case and ABS plastic case have better corrosion resistance than gauges with brass case.

Absolute Pressure Gauges
Unlike other gauges that measure the difference between your system and the atmosphere, these give measurements relative to zero pressure. They’re often used in laboratory applications, and they are barometrically independent.
Stainless steel gauges have excellent corrosion resistance, so they can be used with more corrosive liquids and gasses than gauges with a brass connection and aluminum case.

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.

Shatter-Resistant Sights
The window and body are made from a single piece of plastic, making these sights more shatter resistant than sights with a glass window. They are not rated for pressure.

Sights
These sights have a glass window. Screw them into threaded holes on tanks, gear cases, bearing housings, and mixers to see inside.
Sights with BSPP (British Standard Pipe Parallel) threads are often used with imported equipment.
Sights for dark liquid have a reflector that makes liquid easy to see, especially in low-light conditions.
Aluminum sights have good corrosion resistance.
303 stainless steel sights are more corrosion resistant than brass, steel, and aluminum sights.
