NEW Optris CT P3 Miniature Infrared Pyrometer

With a spectral range of 3.43 μm, the Optris CT P3 miniaturised pyrometer with programmable electronic box, is specifically designed for the non-contact temperature measurement of thin plastic film  materials (with a thickness of less than 1mm) such as Polyethylene, Polypropylene and Polystyrene in the range 50°C to 400°C.
The sensor has a miniature sensing head which is just 29.5mm diameter x 55mm long and allows the sensor to be installed in applications where space is at a premium. Without cooling, it can be used in environments of up to 75°C, and has protection class IP 65. Its 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 DP, CAN bus, RS485, RS232 and USB interface and Compact Connect software.
For the temperature measurement of plastic films such as PET, Polyurethane, PTFE, FEP and Polyamide the Optris CT P7 with its specific spectral range of 7.9 μm is most suitable. For thicker materials it is perfectly acceptable to use the Optris CT LT range of sensors. If you require any selection assistance please do not hesitate to ask.
Calibration as well as a full range of accessories are available for the Optris Compact infrared pyrometers.
