Product Specification

ToughSonic 30 Level & Distance Sensor
Windows PC or Button Setup, Waterproof, Multiple Outputs

The ToughSonic 30 ultrasonic sensor has a maximum range of 30 feet (9.1 meters). Like all ToughSonic sensors, it's built for durability and ease of use in tough industrial environments. It's fully immersible, corrosion resistant, shock resistant and all around tough. It is also fully configurable with SenixVIEW software.

ultrasonic sensors housed in stainless steelThe 1.5 inch (38.1 mm) housing has 1.5 inch NPT threading on each end and a smooth middle section for a variety of mounting options. This sensor has a 9-wire cable that allows up to six simultaneous serial, analog and/or switch outputs. These workhorse sensors are used around the world in remote monitoring and demanding factory environments.

For other sensor sizes and ranges or for chemically resistant sensors, please see the full line of ToughSonic and ToughSonic CHEM sensors.

Non-Contact Ultrasonic Distance & Level Measurement

ToughSonic ultrasonic sensors are built Tough with:
• 1.88 inch (48 millimeter) type 316 stainless steel housing.
• Sealed epoxy potting for wet and dirty applications.
• Ruggedized piezoelectric ultrasonic transducer, potted in place.
• Hardened ToughSonic internal electronics.
• UV resistant, potted-in, 9-wire cable.
• Short and overload protected input / output.

ToughSonic ultrasonic sensors are built Smart with:
• SenixVIEW configuration and analysis software controls more than 60 performance parameters and dozens of viewing, analysis and maintenance options.
• Multi-sensor network capable.
• Up to six simultaneous, industry standard outputs.
