Liquid-Level Transmitters

For Water

For Water With Solids

Also known as level loggers, level sensors, and pressure transducers, these transmitters sit at the bottom of your tank in applications that make traditional mounting difficult. They sense and transmit level information through a signal. All are FM approved for Class I, Divisions 1 and 2, Groups A, B, C, and D; Class II, Divisions 1 and 2, Groups E, F, and G; and Class III, Divisions 1 and 2.

Transmitters with nose cone protect the sensing element from the effects of pressure surges.

Transmitters for water with solids have an unobstructed sensing element that resists clogging and sludge buildup in water with particulate and sewage.

Noncontact Liquid-Level Transmitters

Measure liquid level with sound waves—these transmitters don’t come into contact with the liquid so you don't have to worry about fluid compatibility or contamination. Mount at the top of your tank. The housing is rated NEMA 4X and NEMA 6 for protection from corrosion, washdowns, and temporary submersion.

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. Those with IO Link connect to a programmable logic controller (PLC), so you can remotely change settings and receive error messages. You need an IO-Link controller (not included) to connect.

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.
