CT – Type G5

The Optris CT G5 is a miniaturised pyrometer with a programmable electronic box for applications which is specifically designed to measure the temperature of glass in a wide variety of applications in the range 100 to 1650°C, including flat glass and glass containers.

Categories: Compact Series, Infrared Temperature Sensors for Glass Applications

The sensor has the smallest sensing head available in the world at just 14mm diameter x 28mm long and allows the sensor to be installed in the applications where space is at a premium. The separate electronics enclosure provides a full range of outputs and inputs as standard including Voltage, mA and Thermocouple. It is also possible to incorporate an interface card which provides simple integration into your existing process control equipment. Options include Ethernet, Profibus, RS485 and USB interface and Compact Connect software.

Calibration as well as a full range of accessories are available for the Optris Compact infrared pyrometers.
