Description

The MSE-RT20 Cold and Hot Metal Detector Retro-Reflective Laser Barrier operates over a range of greater than 20 meters (65.6FT) enabling precise detection of hot or cold product in difficult areas.

The MSE-RT20  is a robust sensor especially suited for precise detection and measurement of narrow profile product. Utilizing modulated laser beam with IR filtering enables precise detection of both cold and hot product..

Straightforward alignment is easily accomplished via the visible red Class 3R laser beam. Continuous self-check facility with LED indication of reflector contamination or poor signal return.

The MSE-RT20 cast aluminum housing is supplied with built-in air coolant chamber venting as air purge. Standard operating temperature without air cooling is +50°C (+122°F) and with air cooling is +60°C (+140°F). Optional water cooling is available for an operating temperature up to +120°C (+248°F).

Several reflectors designs are available with temperature ratings from 50°C  (+122°F), 180°C  (+356°F) up to 500°C  (+932°F) . Optional air purged and air cooled reflectors are also available.

The MSE-RT20 provides highly accurate detection over the whole range as a result of a linear laser beam.

The MSE-RT20  is a direct replacement for the MCSL Model LT200M. Please contact us for additional information.
