Laser Measurement Instruments Ltd. Offers Fault Detection Systems. Laser Measurement Instruments Ltd. Manufactures integrated process control systems using a wide range of non-contact measurement technologies designed to improve product quality and reduce manufacturing costs. The company manufactures Process Control, Laser Scanning Diameter Measurement, Ultrasonic Wall and Eccentricity Measurement. The Fault Detection Systems are designed for detection of short-term faults in the diameter of the cable [lumps or neck downs]. The Fault Detection Systems are self-contained instruments with fast response circuitry and solid-state infrared light sources that allow instant detection of changes in the cable diameter. The signal processing and intelligence is built into the gauge head and outputs can be taken straight from the LN Detector that trigger alarms or marking devices when faults are detected.
