Submersible Liquid-Level Transmitters
Best for measuring liquid levels in applications where traditional mounting is difficult, these transmitters sit at the bottom of your tank. They sense liquid levels by measuring the pressure from the weight of the liquid above them. These transmitters continuously send measurements, so you can monitor the status and manage components in your system. Also known as level loggers, level sensors, and pressure transducers.
Transmitters for liquids with solids have sink weights that keep the transmitter in place in applications with moving solids or agitated liquids.

Hazardous-Location Submersible Liquid-Level Transmitters
FM and C-FM approved, these transmitters safely measure liquid levels where explosive gas or dust may be present. Set them at the bottom of your tank in applications that make traditional mounting difficult. They sense liquid levels by measuring the pressure from the weight of the liquid above them. All continuously send measurements, so you can monitor status and manage components in your system. Also known as level loggers, level sensors, and pressure transducers.
Transmitters for liquids with solids have an unobstructed sensing element that resists clogging and sludge buildup in water with particulate and sewage.

Float Liquid-Level Transmitters
Easy to set up and use, these transmitters measure liquid levels using a standard float gauge. They continuously send measurements to a receiving device, such as a programmable logic controller, so you can monitor status and manage components in your system.

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.
