Applications

Industrial sites often show heavy contamination of the soil by oil, toxic and persistent organic compounds. One way to decontaminate these areas is the use of radio frequency heating for soil remediation. This RF treatment technology is a technique where the soil is heated to increase volatility or reduce viscosity of organic contaminants, managing temperature by measuring with a fiber optic temperature sensor / thermometer.

A high- power generator will deliver energy in radio frequency range. The polluted soil is covered with electrodes, which will heat the surface dielectric, fiber optic probes are embedded in the soil to measure and record the temperature levels.

Depending on the level of contamination the temperature will be increased slightly to activate a higher decomposition of soil organisms, alternatively the soil water will condensate in a temperature range up to 150° Celsius together with non-steam resistant organic contaminations. A perforated soil air extraction system takes the steam away and recirculates this into a filtration system.

Optocon systems provide a robust platform for managing temperature in such harsh environments. In addition, data from our devices can be stored and exported to document the process and temperature achieved at the site to ensure a successful decontamination of the land.

Chemical digestion under pressure and temperature for the determination of trace and ultra-trace analysis in downstream processes or synthesis under mild conditions are increasingly carried out in microwave-heated equipment. It was found that under certain pressure and temperature conditions, the yield or efficiency of extraction or digestion processes could be significantly improved.

Fiber optic temperature sensors are the only method capable to  successfully measure temperature in microwave chemistry. The outer jacket of the fiber optic temperature sensor is made out of Teflon, at the sensor tip a GaAs-crystal (gallium arsenide) is attached. The probe sensor is completely non-conductive. Optocon’s fiber optic temperature sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use.

During the process of wood drying and reconstruction of old wooden buildings the core temperature can be controlled via a fiber optic temperature sensor which is located in the wooden beam. The thermal drying of wood components in the installed state between 80 and 95 ° C is sufficient to combat dry rot infestation effectively and to avoid damage.

Optocon’s fiber optic sensors offer complete immunity to RF and microwave radiation with high temperature operating capability, intrinsic safety, and non-invasive use. The probes are also designed to withstand harsh and corrosive environments.

The gallium arsenide (GaAs)-based fiber optic temperature measuring devices (FOTEMP) offer ideal conditions for process monitoring during the wafer manufacturing process, thanks to their wide measurement range from200°C to +300°C and their high accuracy of +/-0.2°C.

Our devices are capable of meeting the strict demands on purity and security inside the production chambers.With total immunity from RF and EMI, Optocon fiber optic probes guarantee precise measurement on silicon wafers with a very low maintenance requirement.

Optocon can provide a fully customized solution for installing the measuring system. Our technology is designed for flexibility to ensure we meet your configuration requirements. Fiber optic temperature sensors can be extended up to several hundred meters without any effect on accuracy or measurement rate of 250ms/channel.

Industrial machines and equipment are often worked to their limits in order to meet production requirements. Running a motor at full, safe capacity can ensure that the asset owner is able to extract the highest output from their process without suffering downtime or excessive wear on the machine and components. Monitoring the motor allows for maximum output, with controlled wear and reduces costly downtime from machine failure.

Fiber optic temperature measurements can operate in this harsh environment without external influence (magnetic fields, radio frequencies, microwaves, hazardous areas) are can be quick and easy to install.

Our fiber optic systems for temperature measurement can be used to detect the temperature in the stator winding of a motor or the storage temperature. Our devices are able to detect and alert the operator to rapid changes in temperature, allowing preventative measures to be implemented and to save machine damage or downtime.

The decisive advantage is the small size of our sensors. Our TS2 temperature sensor and our FOTEMP4, Four-channel monitoring system are ideal for the winding temperature measurement.

There are processes in the chemical and petrochemical industry that require close monitoring and control of temperatures. This may involve critical and hazardous processes. Our challenge as a supplier of process measurement equipment is to meet the requirements of the different processes and our customers.

Specifically for “hazardous installations” our monitoring systems are ideally suited to capture critical temperature developments in the process and, where appropriate, to initiate by alarm-definition countermeasures.

Our probes are intrinsically safe. There are no components in our probes that could create sparks, leading to explosions. Our probes are made of completely non-conductive components (fiber) and can therefore be used in hazardous areas. The fibers can be several hundred meters in length, to enable the installation of the monitoring system, well away from the hazardous area.

Our experience gives us the confidence that our systems can be used to solve customer problems in the harshest of hazardous environments. We have provided solutions that ensure processes are safer and more efficient.
