Product Specification

ToughSonic 50 Level & Distance Sensor
Windows PC Setup, Waterproof, Multiple Outputs

ToughSonic 50 ultrasonic sensors have a maximum range of 50 feet (15.2 meters). Like all Toughsonic sensors, they are built for durability and ease of use in tough industrial environments. ToughSonic 50s are fully immersible, corrosion resistant, shock resistant and all around tough. They are also fully configurable with ultrasonic sensors with stainless steel housingsSenixVIEW software.

ToughSonic 50s are available in three different housings, each with either RS-232 or RS-485 serial interfaces. These 9-wire sensors allow up to six simultaneous serial, analog and/or switch outputs. These workhorse sensors are used around the world in remote liquid level applications and harsh factory environments.

For shorter range applications or for chemically resistant sensors, please see the rest of our ToughSonic and ToughSonic CHEM models.

Non-Contact Ultrasonic Distance & Level Measurement

ToughSonic ultrasonic sensors are built Tough with:
• Type 316 stainless steel housing (except PVC model).
• Sealed epoxy potting for wet and dirty applications.
• Ruggedized piezoelectric ultrasonic transducer, potted in place.
• Hardened ToughSonic solid state 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.
