Temperature sensor covers 40C to 975C

Micro-Epsilon's Optris CT Laser series of sensors suits applications where where users need to detect or scan for hot spots in fast-moving objects in production environments.

A high-performance, noncontact temperature sensor system has been launched, which not only boasts a temperature range from - 40C up to 975C, but also offers 75:1 laser optics and a patented, double-aiming laser crosshairs system, for applications where small spot size is critical and where users need to detect or scan for hot spots in fast-moving objects in production environments.

Launched at the recent Hanover Fair exhibition in Germany, Micro-Epsilon's Optris CT Laser series of noncontact, infra-red temperature sensors combine the accuracy of 75:1 infra-red optics with small spot sizes, low temperature measurement and precision aiming.

The sensor has just been awarded Germany's Industrial Innovation Prize from the Mittlestand Initiative 2007, beating more than 300 other industrial innovation products from Germany into first place.

Ulrich Kienitz, Managing Director of Micro-Epsilon's Optris division, comments: "We are delighted to have been awarded the innovation prize, particularly when there were more than 300 other industrial companies entering the competition".

"First, the small spot size is made possible by a patented, high-accuracy, double-laser crosshairs system that enables temperature measurements down to -40C and as high as 975C".

The double-laser aiming marks real spot location and spot size at any distance, without the need for mechanical shutters.

The 75: 1 optics with selectable focus generates small spot sizes at distances between 70mm and 1260mm.

Apot size is 0.9mm at 70mm, or 1.9mm at 150mm.

Kienitz continues: "Second, as always with Optris products, customers will be very impressed with the price-performance ratio of the sensor".

"The CT Laser F [Fast version] operates on an exposure time constant of just 9ms, and so is ideal for high-speed production environments, where the user needs to scan or detect hot spots on fast-moving objects".

"The nearest competing sensor product that we are aware of operates at 60ms".

The CT Laser can operate up to 85C without cooling, again, around 35C higher than competing products.

Chris Jones, Managing Director at Micro-Epsilon UK comments: "To date, end users and machine builders have been hampered by having to chop the laser signals, having to use larger detectors and having to put up with longer response times".

"The new CT Laser solves these problems at a favourable price-performance ratio".

"The connectivity and range of interface options available on the CT Laser are also second to none".

The range of interfaces available includes a Profibus DP interface, USB, RS232, RS485 and CANbus.

The CT Laser range features selectable analogue outputs 0/4-20mA, 0-5/10V, thermocouple type K or J.
