Ultrasonic Noncontact Level Sensor Switches for Chemicals

Use high-frequency sound waves to detect chemical level. This switch has three relays that can be programmed for multiple set points. Use it to activate several alarms or to automate tank filling and emptying. It’s rated NEMA 4X for protection from corrosion and washdowns.

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.

Rated IP67, all of these transmitters seal out dust and water if briefly submersed.

Digital—Some transmitters 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.

IO-Link Communication Protocol—Transmitters 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.

Ultrasonic Switches

Detect objects and liquid or material levels to set off actions in your system—regardless of size, shape, or surface finish. These switches send out high-frequency sound waves that target small areas, so the surface and structure of your object won't affect results like photoelectric sensors, which sense using light. This makes them great for materials with uneven surfaces, such as granules and powder. They also sense objects when obscured by smoke, dust, debris, or water, but they don't work as well where there's wind, since it could disrupt their sound waves. Once an object is detected or a set level is reached, the digital output sends a signal to your controller to turn components in your system on or off. Use their plug to quickly connect and disconnect to cables with a socket (sold separately). UL listed, C-UL listed, and CE marked, all meet American, Canadian, and European safety standards.

Rated IP67, all of these switches seal out dust and water if briefly submersed.

2 Outputs—Switches with two outputs let you set a minimum level on one output and a maximum on the other—for example, you can keep liquid levels constant by turning on a pump when the level drops too low and turning off the pump when it reaches the maximum.

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

Distance-Measuring Modules for Development Boards

Stream distance readings to your development board in real time. Set up these modules near your robotics, production lines, or liquid monitoring systems to capture changing positioning.

Ultrasonic Modules

Ultrasonic modules use sound pulses to measure distance. They can be used in low lighting. However, they may not be accurate on soft, small, or oddly shaped objects that won’t reflect sound waves properly.
