Temperature Measurement within the Plastics Industry
13 February 2017
The process and production temperature is an important physical measurement parameter for many process techniques used in the plastics industry. Non-contact temperature measurement with an infrared sensor system is thereby a very effective method for process monitoring and control. It supports companies to achieve high quality levels within their production.
Within the plastic industry, the production and testing of products is subject to numerous thermal processes. Infrared thermometers or pyrometers are used for single point temperature measurement if the critical point is known within the process. Infrared cameras are securely established to reveal weak points, especially the compact and fast optris PI thermal imager. Infrared cameras help to visualise thermal procedures and therefore optimise and monitor processes.
Plastic processors are producing a great number of plastic products with different dimensions, thickness, texture, colours and embossing pattern in a roll or tabular. Depending on the framework conditions, infrared thermometers and infrared cameras can be used in different kinds to improve and secure the processes purposefully.
Sensing heads installed in a machinery with laminar air purge collars for temperature monitoring during thermoforming
An important application for infrared temperature sensors is the fitting of pyrometers in thermoforming and packing machines. During the thermoforming process, the original material is being heated up to 190°C with infrared emitters and thermally homogenised. A high homogeneity over the surface and a specific set up of the converting temperature leads to higher quality results during reforming. A defined cooldown in the cooling range closes the process.
To achive a steady product quality of the material and avoid local combustion and crack formation, the optris PI infrared camera is used to regulate the temperature regime during the run into the machine. Pyrometers are then regulating the temperature via selected measurement points.
At a customer of Optris, the infrared thermometer optris CT LT have been setup in one line at the heating zone exit to monitor the temperature profile and visualize temperature gradients. This allows the machine operator to continuously monitor a complete temperature profile covering all used product lots.
Permanent temperature monitoring at an embossing calender, supported by the infrared thermometer optris CT LT
During this application, plastic bulk is being extruded with wide slot extruders into a strap and than calandered to the wanted gauge by cooled and heated calender rolls.The surface (texture) is brought in via the embossing calender.
The original material is heated up to 190°C with a basic temperature within an infrared radiator and homogenised. The material is then transported to the heated embossing calender where it receives a product specific structure. A defined cool down in the cooling range closes the process.
A constant and consistent temperature profile with variances below 5K over the range will be necessary during the embossing process, to obtain a constant thickness, homogenous graduation and the depth of the structure. To monitor the temperature profile during embossing processes, some processors use up to 16 pyrometers optris CT LT measuring in single points which are installed across the moving direction. The temperature measurement merits are visualised at the Siemens PLC (S7). Therefore, it is possible to use the temperature merits for process monitoring and lodge the important process parameter according to the lots into the PLC.
Injection moulding – Reduction of distortion
During the production of injection moulding parts, dimensional stability is of importance. During the injection moulding process the plastic melting is injected with pressure into the temperated tool. The outer skin of the produced component is already set when it is separated. It stabilises the component, as the middle of the component is mostly still liquid and the saved heat slowly gets to the outside. If too much heat is saved in the component during separation, distortion can take place. The result: The dimensions do not fit any longer.
The optris PI thermal imager contributes to the optimisation of the tool temperature via the heating and cooling systems. A 120 Hz online monitoring can detect the maximum component temperature after separation. Reaction to temperature changes can therefore take place. The closing time needs to be raised if the temperature is above the specifications; if the temperature is below the specifications, the closing time needs to be shortened.
Infrared camera detects weaknesses at injection moulds
Until now, only samples of the temperature were taken and longer closing times set up precautionally - a huge waste of capacities. The optris PI infrared camera comes in handy for the production of injection moulding parts. The camera monitors the temperature of the production without disruption and without contacting the parts. The productivity increases as more components can be produced at the same time.

New Non Contact Measurement of Glass Production
13 February 2017
Line scan camera for the production of glass panes and container glass
VGA infrared camera with 7.9 µm filter for the glass industry
Again, Optris GmbH introduces a new infrared camera for the glass industry at the glasstec 2016. With its 7.9 µm filter, the thermal imager optris PI 640 G7 is perfectly suited for the measurement of glass and, due to the VGA resolution, offers an even wider range of possible fields of application. “The software optris PI Connect enables the use as a line scan camera, which is essential for the temperature control of glass ribbons and glass panes” declared Torsten Czech, Head of Product Management at Optris.
Temperature measurement under difficult conditions
Temperature monitoring is crucial in the glass industry and it is an integral part of almost all stages of the production process. In confined and hot surroundings, temperature can sometimes only be determined by room sensors. The compact infrared thermometers and cameras of Optris enable the operation even in confined spaces with high temperatures. The thermal camera monitors the temperature distribution in cooling processes of flat glass production as well as in the production of container glass.
Glass requires special sensors
For the accurate measurement of temperatures, emissivity is a key factor. Glass usually exhibits an emissivity of 0.85 µm in the longwave range. In processes with higher temperatures, it is measured with 5.0 µm or 7.9 µm because in those spectral ranges the emissivity is ≥0.95. The main advantage of 7.9 µm is the lower angel dependency of the emissivity.

How Often Should a Thermometer be Calibrated?
12 Jan 2016
Ten minutes on Google yields a range of answers – from “regularly if not daily” to “annually” to “after being dropped”. If the thermometer has a calibration certificate from a laboratory accredited to ISO 17025 then it is unlikely to show a recalibration date – this is because the issuing laboratory will not want to imply specific time validity or be seen to “guarantee” the performance over a certain time period.
It is for the user to determine re-calibration schedules based on the application and how a thermometer is used. Some people may be happy to make measurements with a view to determine the temperature to a few degrees and even if there was some unexpected result the consequences may be trivial. Yet for other people making a temperature measurement with only a small error might be disastrous – perhaps compromising product quality, energy savings or even human life. Many people will determine an annual calibration period – and use an accredited laboratory to ensure “best practise”.
As an example, Joseph works in the food sector; he uses a thermometer to comply with the Food Safety (Temperature Control) Regulations 1995 and he adjusts and keeps a daily log of many large refrigerators to ensure the food is stored at or below 8°C. He has the thermometer calibrated every year; one year the calibration laboratory calls to say when recalibrating the thermometer it has shifted by a 5°C; there must be some damage to the thermometer or fault with its display. Joesph now has a dilemma – his logs show the food has been stored at 5°C but with this shift it has actually been at 10°C. An offence has been committed; the food has been kept at a temperature which could cause a risk to health – and his company’s future.
Joesph doesn’t know if the problem started the day before he sent the thermometer away - or six months ago, or a year ago when it came back from calibration.
The dilemma could have been easily avoided, by checking regularly in a flask of melting ice, by having a second thermometer and doing cross checks or investing in simple temperature calibration equipment. An annual calibration was not sufficient in itself.
Sensors at high temperatures and sensors regularly being cycled over a wide range are particularly prone to drift and will need to be checked at more than one point. Isotech produce portable calibrators covering temperature ranges from -100°C to 1200°C along with high accuracy thermometers and instruments.

XCO Continuous Thermocouple
15 Sep 2015
Temperature Controls are now supplying the Australian market with the XCO Hot Spot Continuous Thermocouple.The Continuous Thermocouple is designed to sense temperature increases in areas too large (or important) to be covered by multiples of typical temperature sensors (e.g standard thermocouples or RTD's)
- Hazardous material Silos
- Process Lines
- Coal Bunkers
Continuous Thermocouples generate a measurable voltage like normal thermocouples, however, the measuring junction in a Continuous Thermocouple is not formed by directly joining the two wires. More remarkably, the measuring junction is not fixed but, when subjected to an increase in temperature, becomes concentrated at the hottest point anywhere along the sensor's entire length. This is due to the large fall in resistance in the insulating material at the heated area.
