TruSense S-Series Laser Sensor

The Smallest, Most Powerful, Lowest Cost Laser Sensor on the Market.

TruSense S-Series Overview

The TruSense S200 Series laser sensors. These next generation laser sensors offers longer range, a more simplistic user interface and a smaller, compact design – all at a lower price point.

The S-Series laser sensors are user configurable, which means you can easily optimize their performance for your specific application. For example, you can set the measurement mode to First, Strongest or Last and quickly change the behavior of the laser sensor to best work in your particular environment.

You can also increase the averaging samples to capture a higher accuracy level of all your measurements. If you need to isolate the measurement within a particular range, you can set a short and long gate and program the laser to only compute values within that predetermined range.

Apply an offset from the laser sensor and have unlimited flexibility with where you install your laser sensor. All these benefits will help produce the desired results you need within your specific environment.

The TruSense S210 and S230 models are the latest additions to the S200 laser sensor series. These models are designed for optimal operation and performance in industrial applications including Plant Management and Automation, Security and Surveillance, Vehicle Guidance and Automation and Traffic Management.

The TruSense S230 industrial laser sensor and ruggedized enclosure are a perfect solution for a wide variety of plant management applications. This model utilizes a visible alignment laser and offers serial RS232 and 4-20mA outputs. This output format is critical because that tends to be the most commonly used data input/output for industrial applications. In addition to a 4-20mA output, the S230 model includes HART capability allowing the user freedom to communicate with the laser through 4-20 as well as through RS232 serial communication.

For applications where a compact size and extremely light weight is a must, the TruSense S-Series are a perfect fit. The OEM version (without an external case) weighs less than 3 ounces and takes up space that is no larger than a deck of cards. System integrators can easily install it into a small aircraft for height measurements or camera housing.

Small size does not limit the performance of these sensors as they will range to a gray target at over 1500 meters with accuracy up to 4 cm in short range mode. Having a choice of a variety of I/O formats makes the TruSense series very adaptable for your specific installation.

The superior engineering put into this laser sensor equates to a smaller, lighter, better performance laser sensor - all at a very competitive price.

How the TruSense Laser Sensor Measures Up:

  • Easily identifies difficult targets such as liquids, non-reflective material and fast moving objects.
  • Makes non-contact and non-intrusive measurements without the need for frequent calibration.
  • Recognizes small targets at long distances, within narrow openings and from sharp angles.
  • Performs under temperature variations, background noise, vapor pressure and low dielectric or acoustically absorbing materials.

The TruSense S200 series family of laser sensors are lightweight, compact and affordable. Offering three different models including the S200, S210 and S230, these laser sensors have up to +/- 4 cm accuracy, have a smaller footprint and are housed in a glass-filled polycarbonate packaging.


Communication Protocols Used by the S200 Series

Communication Protocol S200 S210 S230
RS-232 output
0-5 VDC output trigger  
4 – 20 mA output    
4 – 20 mA and HART output    


The series has three standard target modes - first, last and strongest.

Target Modes in S200 Series:

Target Mode Definition Recommended Use
First The unit only measures the first target it sees When no obstructions exist between laser sensor and intended target
Strongest The unit measures to the strongest target it sees When an obstruction, such as a fence, exists between the intended target and sensor
Last The unit measures to the last target it see To get better results through dust and haze


Difference between S200 Series and ULS Lasers

Customer Requirement S200 S210 S230 ULS
High data output rate required (>14Hz)      
Highest accuracy (<4 cm)      
Greatest range (dependent on accuracy)  
Lighter weight/size  
Lower cost  
4 – 20 mA output required    
4 – 20 mA and HART output required*      
Need RS-232 output
Need RS-485 output      
Requires build-in laser alignment
