Oil-Level Indicators




Monitor hydraulic fluid or oil level in gear boxes, crank cases, and other reservoirs. These indicators mount from the outside of your tank. The gauge shield rotates 360° for optimal viewing from any direction. They are for use in nonpressure applications. All have a vent to prevent pressure from building up and causing an inaccurate level to display.
Indicators with swivel fitting have a two-piece construction so they can be quickly disconnected.
Indicators with drain allow you to sample hydraulic fluid from the reservoir.

Ultrasonic Transmitters
Measure the distance to objects and the level of liquids and materials despite size, shape, or surface finish, and send that information to other parts of your system. Unlike photoelectric switches, which use light to detect objects, these transmitters emit high-frequency sound waves that target small spots, so the surface and structure of your object won’t affect results. This makes them great for materials with uneven surfaces, such as granules and powder. They also sense objects in dirty and wet places, but they don’t work well where there’s wind, since it could disrupt their sound waves. Use their plug to quickly connect and disconnect to cables with a socket (sold separately). UL listed, C-UL listed, and CE marked, they meet American, Canadian, and European safety standards.
All transmitters have an analog output, which means they continuously send measurements to monitor status and manage components in your system. Some also have a digital output that signals your controller to turn components on or off whenever an object is detected or a set level is reached.
90° elbow transmitters are compact to fit in tight spaces. They’re best for conveyors.
Rated IP67, all of these transmitters seal out dust and water if briefly submersed.
