The MSE-V280 operates optically without contact, and implements the principle of the dpatial filter by meas of the use of a CCD sensor. Spatial filter is the generic term used ti describe a meaning principle for the non-contact determination of the velocity and length of moving materials. The spatial filter is based on the filtering effect of grid-like structures(grid modulation). The function of the MSE-V280 can be secribed as follows: The object to be measured is reproductd through the objective onto the CCD sensor. The CCD sensor is operated as an optical gird (no image pickup). The object to be measured is illuminated by an integrated light source(LED). External lght disruptions are effectively suppressed with this method.
When the object is moved, a signal frequency is generated due to grid modulation. This frequency is proportional to the velocity at whch the object is moving. The device measures the signal frequency and converts it to a velocity value. There are several control circuits that enable automatic adjustment to the most varied of materials (material surface structure and brightness).
The new MSE-D301 Laser distance sensor measures distance and speed of natural targets without a reflector. A reflector can be used for increasing the measuring range. The sensor needs only a very short time to measure; it facilitates distance measurement to or from moving objects. The laser pulse's time-of-flight measurement principle which it uses is specifically suitable where great distances have to be measured and for applicationd in harsh industiral environments. With the compact design shape, simple setup and configured with standard interfacing facilities; the MSE-D301can easily be installed. For interfacing an analogue output, 2 digital outputs and a serial interface RS232 or RS422 are available. Standard MSE-D301 delivery includes integral heating, a status display and a red Laser pointer. A modular setup allows for easy comlementation with accessories or special models as may be required in particular applications.
The MSE-D150 Laser Distance Measurement Sensor is designed for mobile and stationary distance measuremen in a indusrial enviroment. The MSE-D150 works based on comparative phase measurement. To achieve this, it emits visible laser beams in different frequencies. The target being measured returns diffusely reflected light that is subsequently compared with a reference signal. Finally, a microprocessor uses the recorder phase shift to calculatea required distance with mm accuracy. The sensor MSE-D150 distinguishes itself through a high precision as well as big independence of the surface of the measured object. The MSE-D150 is design for fast measurement on a white terget. The red, well visible laser beam allows a simple alignment.
