The new Optris Infrared Thermometers CThot , CTglass and CTlaser bring the heat under control

The Optris GmbH is expanding the product range of infrared thermometers:

The new Infrared Thermometer optris CThot:

The optris CThot allows temperature measurements and the use of the IR sensor head under environmental temperatures up to 250°C without any need of cooling. New detector materials, a new mechanical design and high temperature cables allow the optris CThot to withstand harsh environmental conditions. A robust and massive but yet compact housing is adaptable to common industrial mountings, brackets and flanges.

More and more modern heat treatment lines are constructed inside the machine in a very compact design for high process efficiency , there is no way to place sighting tubes etc. for measuring from outside the process chamber. Compact (IR) sensors withstanding the heat inside the process chamber/oven are the deal.

Main application field of such type of sensors is the control of drying and finishing processes of textile fabric, carpet, paper, cardboard, corrugated paper, plasterboard sheets, timber and plastic compounds. optris CThot sensors inside heat treatment lines with several process chambers measure temperatures of the web/fabric at different points over the length and the witdth. The customer gets information about the drying curve , moisture content, non uniform application of coatings and fixing. The process engineer can optimize the energy flow and energy consumption, the speed and the product quality.

The narrow beam optics of these sensors with a high optical resolution of 10:1 allows oblique aiming to avoid material dependent temperature readings. U nder these oblique viewing angels the effective emissivity of textiles is independent of its thickness and type of fabric. So the customer can measure thick textile fabric or light fabric like curtain material in the same way.

A response time of 30ms is a big benefit and is setting a benchmark in these sensor family. Most of the rival products are much slower (in the range of seconds) , and they have a more worse optical resolution (1:3 or less) , making material independent measurements more difficult.

The optris CThot is usable in a varity of applications in dryers, ovens, heat treatment lines in the metal and glass industry, paper, plastic and textile manufacturing and semiconductor processing in the temperature range of -40 to 975°C.

The monitor box for programming and temperature display allows the easy wiring of the standard analog outputs 0/4-20mA, 0-5/10V , thermocouple type K or J.

Optris offers for all CT series infrared thermometers an integrated Profibus DP interface (optional) or other plug in digital interfaces (optional) like USB, RS232, RS485 or CAN.



The new miniaturized Infrared Thermometer CT 2M for high temperature measurements - one of the smallest worldwide:

The miniaturized Infrared Thermometer CT 2M with 1,6µm wave lenght range was designed for measurements of metals , of secondary metal processing , metal oxides and ceramic materials.

The very small sensing head of the CT 2M with 14mm diameter and 28mm length fits everywhere into small and tight environments. It is usable up to 125°C ambient temperature without cooling.

The measuring temperature ranges from 250°C to 1600°C , an optics of 75:1 with measuring spots up from 1,5 mm is setting a new standard in this class of instrumentation. A new detector and a fast signal processing allow response times up from 1 ms.

The short measuring wave length of 1,6µm reduces error of temperature readings on surfaces with low or unknown emissivity.

High electromagnetic compatibility (EMC) allows applications in induction welding and soldering processes.



The new Infrared Thermometer optris CTglass with 5,2µm wave length:

The optris CTglass is designed for accurate glass temperature measurements on flat glass lines, container glass machines, in the bulb manufacturing, car glass finishing and the production of solar panels in the temperature range of 100 up to 1650°C.

The measuring wave lenght of 5,2µm provides a low depth of penetration for the infrared measurement , because the transmission of glass within 5,2µm is very low. With the use of shorter wave length the infrared thermometers would measure through the glass, with a longer wave length reflection effects occure.

The measurement of temperature at critical locations in the process line is essential for a overall control of glass product manufacture.

In container glass manufacturing the operator has to obtain the measurement of gob temperature to observe the ratio between glass viscosity and gob weight. The mould temperature measurement is important for balancing the cooling levels of mould shells.

In sterilisation procedures of glass bottles for pharmaceutic products a certain temperature level control is essential.

A wide field of applications in the production of flat glass, construction glass and automotive glass are measurements in bending ,annealing and tempering zones to get a high homogeneity of the whole glass panel.

A very modern field of applications we find in semiconductor processing and the manufacturing of solar cell panels where glas is used beside other materials as a basic substrate.

The double laser aiming of the optris CTglass marks the real spot location and spot size up from 1mm at any distance. This helps in all modern applications where “size of spot matters”.

A robust but yet compact stainless steel sensor head is adaptable to common industrial mountings.

The optics 70:1 with selectable focus provides a smallest spot of 1mm , the smallest spot of competitors is 2,5mm in this class of devices.

The optris CTglass is usable up to 85°C ambient temperature without cooling and has an automatic laser switch off at 50°C . Cooling and protection accessories for harsh environmental conditions are available.



The Infrared Thermometer optris CTlaser with 75:1 optical resolution:

The optris CTlaser is an all purpose universal high performance infrared thermometer for the temperature range of -40°C to 975°C. Its predestinated for most of all noncontact temperature measurements in industrial applications where “size of spot matters”.

The optris CTlaser combines the accuracy of a 75:1 infrared optics with small spots sizes, the low temperature measurement and exact aiming. And all of this within an affordable price Optris is famous for.

It allows low and high temperature measurements of smallest spots up from 0,9mm without the need of mechanical choppers. The double laser aiming marks real spot location and spotsize at any distance. The optics 75:1 with selectable focus at distances from 70mm to 1260mm is generating unbeatable small spots at low temperatures of 0,9mm at 70mm or for instance 1,9mm at 150mm distance.

The measurement of small spots is much easier at higher temperatures. A wide varity of such kind of art infrared thermometers is available on the market. The low energy measurement at lower temperatures needs within classical pyrometers: choppering of signals, big size of detectors or/and longer response times. The new super sensitive detectors, developed at Optris, bring these challenges under control.

The optris CTlaser F (fast) is dedicated for scanning of fast moving objects at low temperatures up from 9ms exposure time.

The optris CTlaser is usable up to 85°C ambient temperature without cooling and automatic laser switch off at 50°C . It features analog outputs 0/4-20mA, 0-5/10V , thermocouple type K or J and the optional integrated Profibus DP interface or other plug in digital interfaces (optional) like USB, RS232, RS485 or CAN.

The CompactConnect Software is used for easy sensor setup and remote controlling, it supports multi tasking. It has a Graphic display for temperature trends and an automatic data logging for analysis and documentation with 1 ms response time. The customer can do adjustments of signal processing functions and can programthe outputs and functional inputs of the sensor. It allows automatic emissivity adjustment. It makes customization of sensors to customer needs easy.The software CompactConnect is included in all Optris RS232 and Optris USB interface accessory kits.
