Ultrasonic Level Transducer 2-wire with USB Widget: 500/3107
Astles Ultrasonic Level Sensors provide a 4-20mA output to give a real-time reading of chemical storage tank levels. These sensors are suitable for small tanks with non-foaming, non-condensing liquids such as water, wastewater, acids, and oil.
-
Continuous non-contact level measurement up to 1.25m below sensor.
-
4-20 mA output for longer signal distances up to 300m.
-
Configuration is fast and easy via software and our USB adapter.
-
Narrow 2.5cm beam width and short 2.5cm dead band optimized for small tanks.
-
PVDF transducer and 6P polycarbonate enclosure for corrosive liquids.

Tuning Fork High-Level Switch: 500/3108
Astles Tuning Fork Level Switches are typically used as high-level switches to help prevent overfilling of storage tanks. They can also be used as low-level switches. For use in hazardous locations, the intrinsically safe ultrasonic level switch provides high or low liquid level detection of chemical, solvent, or low viscosity petroleum-based liquids with a 1A relay output. Process examples include hydrochloric acid, acetone, and diesel fuel oil. The submersible PP level switch sensor is universally mounted through the tank wall or inside the tank and connected to a PLC or relay controller.
-
Suitable for use in hazardous environments.
-
Submersible polypropylene sensor for use with corrosive liquids.
-
60VA SPST relay selectable NO or NC via power supply wiring polarity.
