Rugged and reliable sensor since 20 years

Since 20 years the MI250 is known as a reliable proximity switch for temperature up to 250°C. Leading automotive companies use it in their production facilities.
The MI250 is used in burn in ovens and paint systems 24 hours per day. The MI250 reaches average life time of 7 to 10 years under these conditions.
A sudden failure in a burn in oven could lead to a interruption of the production for several days. This is the reason why our customers expect the long life time and reliability of our products.

Proactive intelligence against production stop

To reduce unwanted production stops the new MI250-D has been developed. The new sensor monitors permanently the function of the sensing element.
When the sensing element shows weak response, the electronic system creates an alarm; several weeks before the sensors function will fall unreliable. This helps to exchange the sensor during the next planned maintenance intervention. The consequence of a defect during production can be avoided.

Additional protection with a "BlackBox"

An additional feature is the integrated recording of machine parameters, like the black box in airplanes. Temperature and duration of temperatures intervall are recorded. This allows to detect precisely the reason of failure after years in production.

Application

The MI250-D is a reliable sensor for control and monitoring of production processes under high temperature where other sensors could not be used, like burn in ovens, dryers, hardening-, sinter- and paint systems.
