ToughSonic 50

Maximum Range 50 feet (15.2 Meters)

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 housings SenixVIEW 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.

ToughSonic 50 Options


The ToughSonic 50 is available in three different housings. All sensor features are available with any housing


Our Standard Model (TSPC-21S) comes in a 2.1 inch (53.34 millimeter) smooth 316 stainless steel housing for easy clamping.

Rear Mount

The Rear Mount Model (TSPC-21SRM) adds a stainless steel end cap with 1.5 inch NPT threading to the 2.1 inch smooth standard housing.

PVC Model

The PVC Model (TSPC-25P) is packaged in a 2.5 inch PVC housing with 2.5 inch NPT threading on either end for tank level applications.

Serial Interface

The ToughSonic 50 is available with one of the following Modbus serial data interfaces.

Modbus RS-232 serial data interface

Modbus RS-485 serial data interface
