HiTECH Technologies, Inc.
Industrial Mini Lasers For Distance Measurement Theory of Operation. The LDM 41/42 P Laser Distance Measurement Sensor with Profibus DP interface is designed for distance measurement applications in an industrial environment. The LDM 41/42 P works based on comparative phase measurement. To achieve this, it emits a visible Laser beam with different modulation frequencies. The target being measured returns diffusely reflected light that is subsequently compared with a reference signal. Finally, a microprocessor uses the recorded phase shift...

Norbar Torque Tools, Inc.
Ultrasonic Measurement of Bolt Pre-Load Ultrasonic measurement of bolt pre-load is made possible by introducing a sonic pulse at one end of the fastener and accurately measuring the time of flight (TOF) required for the echo to return from the opposite end. Using material constants, the USM-3 converts this TOF into an "ultrasonic length" of the fastener, providing a baseline from which future measurements will be made. When the fastener is tightened, the TOF increases and the USM-3 will again utilise material constants to eliminate...

Olympus IMS
Visible and Nonvisible Imaging Techniques technology remains the same as for visible-light confocal; however, a 1310-nm wavelength is used. Because of the transparency of silicon, repeatable and accurate measurements can be made through the silicon base at this wavelength to measure whether the wafer has bonded. This technique likewise requires neither sample preparation nor advanced interpretations by the operator, both of which are sometimes required for ultrasonic tools designed for opaque substrate measurement. The emergence of these new... (read more) -

Micro-Epsilon
Custom inductive measurement Inductive sensors are one of the traditional electromagnetic measurement techniques. These sensors consist of one or more coils and guarantee long operating life by using a non-contact, wear-free measuring method. Many different versions are available on the market, but specific applications require specific sensors. This is often necessary due to special installation conditions where the measuring range or the design of the sensor must be modified. The sensor electronics can either be separate...
