At Sensors Expo 2019 in San Jose, CA, Clint Cowan from Laser Technology demonstrates and explains the company’s time of flight laser technology for detection in an intelligent gate and its TruSense S300 sensor for non-contact fluid-level sensing in clear water.
With the intelligent gate, if a person is inside of 3 feet, the laser sensor sees the person but will not trip the light. In the 3 to 15-foot range, the sensor detects a person and triggers an alarm light. For flexibility in security and safety applications, the sensor can be adjusted to target certain measurements. It can detect if something is supposed to be there and is not or if someone is not supposed to be there but is. It can trip a sign, a light or warning system or send a notification to a cell phone.
The company’s S300 laser sensor offers long range, a simple user interface and a small, compact design for liquid level applications. It can accurately measure fluids that have highly reflective fluid surfaces such as those on clear water as well as turbulent fluids and those with any dielectric properties. With a range from 1.5 ft (46 cm) to 164 ft (50 m), the sensor can be set to isolate a measurement within a specific range. By setting a short and long gate, the laser can be programmed to only compute values within that predetermined range.
Target applications include water and wastewater, chemicals processing, and food and beverage industries.
