High Liquid-Level Alarms for Sump Pumps
An alarm and a red light alert you when water levels rise too high. A float detects water level and activates the alarm. Alarm has a plastic housing that meets NEMA 3R for protection from dirt, falling liquids, and light splashing.

120V AC | 82 dB @ 10 ft. | Three Prong | 20 | NEMA 3R | 0000000 | 0000000 |
Pop-Up Full-Tank Indicators
Avoid overfilling—these indicators pop up when your tank is almost full.
Indicators with a polypropylene float have a plastic window to protect the indicator’s movement and keep it working properly. When you see the indicator behind the overfill alert warning, you'll know your tank is almost full.
Alarms flash and sound when your tank is almost full.

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.

Noncontact Liquid-Level Transmitters
Using high-frequency soundwaves, these transmitters measure the levels of corrosive, dirty, or sticky liquids without coming into contact with them. They’ll continuously send measurements, so you can monitor status and manage components in your system. Mount at the top of your tank. There should be no tank walls, agitators, or other objects in the path of the soundwaves.
Ultrasonic transmitters are often used to measure water, wastewater, chemicals, and oil but won’t work on vapors, foam, and other media that’s difficult to measure. The included fob allows you to connect your transmitter to your computer, where you'll download software that guides you through the setup process to make sure you get accurate readings. Ultrasonic transmitters with a button interface can be set up and calibrated without the fob. Transmitters with a switch can also signal your controller to turn components on or off when they reach a set level.
Radar transmitters are best for liquids that are tricky to measure because they work even if there’s condensation, foam, or other difficult conditions. They also measure the level of liquids with solids and small solids. In addition to the traditional 4-20 mA output, these transmitters can also send measurements to your Android smartphone or tablet using Bluetooth. There’s an app you can use to set up your transmitter and calibrate it for your system.
NEMA 6P rated transmitters protect against dust, weather, washdowns, corrosion, and submersion. IP68 rated transmitters seal out dust and water from 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. NEMA 6 rated transmitters also stand up to weather and washdowns.

Noncontact Level Switches for Water
Detect water level with infrared light to avoid false switch activation caused by vibration in your tank. Also known as optical switches, these sense the level by reflecting light into a receiver that sends an output current to activate an alarm or control circuit. They are sensitive to light and should be shielded or used in enclosed tanks. Mount them horizontally or vertically.
SPST-NO switches activate when the tip is submerged in liquid and light stops reflecting into the receiver.
SPST-NC switches activate when the tip is exposed to air and light reflects into the receiver.

Sanitary Level Switches
Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean. Highly polished, they prevent bacteria from growing. They also stand up to hot spraying water, chemicals, and cleaners common to food plants, thanks to their PEEK probe, stainless steel body, BSPP threads, and IP ratings. Their IP67 rating also means they won’t fail if under water temporarily.
To connect to automated systems and remote displays, these switches work with IO Link and 4-20 mA analog output, making them good for hard-to-reach areas. Program the colors on the LED indicator to tell you what the switch is sensing.
USP Class tested, the plastic in these switches won’t leach chemicals. They’re also C-UL listed and CE marked to meet Canadian and European safety standards.
Use quick-clamp adapters to connect these switches to quick-clamp sanitary tube fittings.
Note: Solids and liquids must have a dielectric constant of at least 1.5 to detect them.

Water Overflow Buzzers
When water contacts the sensor, it triggers a buzzer to alert personnel to a leak or overflow hazard. Frequently used to monitor sinks, pipe lines, tubs, and sump pumps.

Wi-Fi Enabled Water Overflow and Freeze Detectors
Keep an eye on leaks, overflow, and temperature changes near your equipment, even when you’re offsite. These detectors connect to your Wi-Fi to send alerts about moisture, temperature, and humidity to your smartphone or tablet. Place them near tanks and tubs to watch for overflow, or near sump pumps and pipe lines to monitor temperatures and prevent frozen pipes. When water touches one of the sensors on the detector, a buzzer also goes off, alerting anyone nearby. Rated IP44, these detectors are protected from objects larger than 1mm, such as wires, and from water splashing in any direction.
Download an app onto your smart device to program temperature and humidity ranges and set up alerts. You can also create reports that show changes in temperature and humidity over time.
To extend the area they monitor, these detectors come with a detachable cable sensor that senses moisture along its entire surface. Swap in replacement cable sensors for worn sensors, or link several together to wrap around large equipment or trace the path of a pipe. Extend them up to 500 feet from detectors.

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.
Switches with PNP/NPN signal output automatically produce the signal you need based on the connected device.
90° elbow switches are compact to fit in tight spaces. They’re best for conveyors.
Rated IP67, all of these switches seal out dust and water if briefly submersed. NEMA 6 rated switches also stand up to weather and washdowns.
