TruSense® S300 Series

The Ultimate Sensor Engineered to Measure Fluids without Contact

Description:

Consisting of the S-300, S-310 and S-330, this laser sensor series generates accurate measurements on a wide variety of liquids, even clear water. Data collection in fluid level measurement is now consistent and accurate as these sensors smooth out the reflective peaks and valleys caused by fluids in random motion. Directly measure calm or turbulent liquids with accurate and repeatable results instantaneously. The narrow beam of the sensor can be shot through stilling pipes and near flat walls.

Overview

When compact size and extremely light weight are requirements, 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. User configurable so you can easily optimize their performance for your specific application and quickly change the behavior of the laser sensor to best work in your environment.

Specifically engineered for non-contact fluid level measurement, these sensors directly measure fluids that are calm or turbulent, and regardless of their dielectric properties. An ideal solution for the measurements needed in applications such as Water and Wastewater, Chemicals Processing, and Food and Beverage industries. The S300 sensors can easily integrate with your product solutions by using the TruSense OEM versions.

Attach the optional diffuser lens to obtain accurate measurements under challenging conditions, such as clear or highly turbulent liquids.

The Ruggedized Enclosure is an explosion-proof accessory which allows the laser sensor to be rated to meet ATEX and other explosion-proof standards. It is ideal for applications that require Class 1, Div 1 explosion-proof protection.

A choice of I/O formats makes the TruSense series very adaptable for your specific installation.

The S300 series of laser sensors are up to the challenge and ready to provide accurate and repeatable results in the world of fluid level measurement.

Key Features

The TruSense S300 Laser Sensor Offers Advantages Like No Other:

  • Provides instantaneous measurements that are very accurate, even over long ranges
  • Avoids false echoes by creating a beam with virtually no spread that can be shot through narrow spaces or small-diameter stilling wells
  • Installs at the top of a well for easy mounting, access and maintenance
  • Saves time with little to no required calibrations
