Ther­mo­graphy in Chem­ical Industry

Epoxy resin systems are mostly used as a matrix material in fibre composites. In a variety of manufacturing processes, the corresponding resin system is processed in a flowable state. The material only acquires its rigidity in a subsequent curing process. This is characterized by an exothermic chemical reaction with a pronounced temperature dependence.

All kind of hot industrial processes need to be contained well to allow the process itself to go on and at the same time to protect neighbouring installations and employees working there. Thermography helps to detect weak points and provides first indications for necessary repairs.

In the chemical industry, thermography is used for the inspection of plants, the monitoring of processes and the early detection of overheating. Sauer Engineering offers infrared measurements with infrared cameras from InfraTec.

Contactless measurement of temperature distributions and profiles with industrial thermographic cameras permits efficient monitoring and control of temperature-dependent processes and procedures within a system-integrated quality assurance programme in industry.

Check the microstructures of sheet metal parts during the stamping process and establish a uniform high strength and quality of all produced stampings safely and with a contact-free method.

Using pulse thermography, WELD-CHECK enables you a quantitative assessment of the inspected welds.

Effectively secure your goods and appliances by integrating thermography into an automated early fire detection solution.

Calibrated measuring cameras offer the option of a completely automated site surveillance by utilising temperature alarms – an approach well beyond the simple and susceptible motion detection systems used elsewhere. With IROD InfraTec offers a scaleable, powerful system solution.

The IR Substation Monitoring System GRID-DETECT uses infrared technology to monitor the temperature of substation components to secure the reliability of substation.

As a supplement to other monitoring systems, InfraTec offers thermographic systems that have ATEX-certified protective housings and pan/tilt systems. Depending on the requirement, these can be used in different protection zones for the gas and dust area. ATEX-compliant protective housings and pan/tilt systems are used in numerous areas.

The InfraTec product range includes numerous protective housings. The all-weather and robust metal housings allow the use of the thermal cameras in harsh environments and protect against mechanical stress, dust and splash water. Depending on requirements, users can also choose ATEX-certified protective housings that can be used in potentially explosive atmospheres.

The 10 Gigabit Ethernet interface of the high-end camera series ImageIR® opens this extremely fast transmission standard with a NIC specially developed by InfraTec. This works with optical or electrical transceiver modules that are easy to change and are called SFP+.

Stationary camera systems are usually used PC-controlled. Alternatively, InfraTec offers a solution that makes the operation of the camera system even more versatile. An additional tablet PC is attached to the camera housing, which enables wireless control of all camera functions. The display solution allows access to all functions of the IRBIS® online control and acquisition software, delivered together with the camera.

The combination of a separate filter and aperture wheel, allowing a total of 35 freely selectable combinations, is prerequisite for a universal application in measurement tasks with high object temperatures and in the field of spectral thermography. The neutral density filters used for signal attenuation or the combination of spectral filters and apertures reliably prevent interference effects.

The multispectral feature makes it possible to record sequences with constantly changing spectral filters. Images are recorded synchronously with a rapidly rotating filter wheel equipped with the filters. It may be possible to switch between up to seven filters, depending on the version. Due to this the multispectral measurement can be optimised to suit the measuring task if the preset ranges are unsuitable. The integration times can be adapted within the limits calibrated for this filter.

The Auto Calibration option expands the HighSense function to include automatic, dynamic adaptation of the integration time. This ensures the utmost temperature measuring accuracy and an optimised signal-to-noise ratio throughout the process. The wellfill of a detector is usually optimal in certain areas of the dynamic range. If the measured object signal is outside theses or user-specified limits, the integration time is readjusted.
