TruSense® S200 Series

Designed for Level Measurement, Detection and Positioning


Laser Tech’s TruSense® S200 series of laser sensors are lightweight, compact and affordable. Three different models (the S200, S210 and S230) all have up to ± 4 cm accuracy, a small footprint, and are available with or without a glass-filled polycarbonate housing.

Overview Downloads Primary Applications Key Features Specs


TruSense® S200 series sensors range to a gray target at over 750 meters with accuracy up to 4 cm in short range mode (1,500 meters in long range mode).

The S210 and S230 models are designed for optimal operation and performance in industrial applications involving Level Measurement, Detection and Positioning.

The S230 industrial laser sensor and ruggedized enclosure are a perfect solution for a wide variety of chemical process applications that require an explosion-proof housing. The 230 model utilizes a visible alignment laser and offers serial RS232 and 4-20mA outputs, which are commonly used data input/output for industrial applications. Support for both these protocols allows the user the ability to communicate with the laser through 4-20mA as well as through RS232 serial communication.

It has an explosion-proof accessory (Ruggedized Enclosure) which allows it to be rated to meet ATEX and other explosion-proof standards.

Key Features

Choose from a variety of Communication Protocols

We have models that provide RS-232, 0-5 VDC, or 4-20mA output.

Equipped with Multiple Target Modes

First Target Mode:  The laser only measures the first target it sees.  Ideal for when no obstructions exist between the laser and the intended target.

Strongest Target Mode:  The unit measures to the strongest target it sees.  Ideal for when an obstruction, such as a fence, exists between the intended target and the sensor.

Last Target Mode:  The unit measures to the last target it sees.  Ideal for getting better results through dust and haze.
