Precise temperature monitoring


Ceramicx, a company from Ireland, develops and produces infrared heating elements. These devices generate infrared radiation (IR) in order to heat objects on a non-contact basis.

These heating elements are used when composite materials or plastics need to be heated as evenly as possible without contact. When the heating temperature is too high or too low, this can lead to faulty shapes, inconsistent hardening and subsequent quality issues.

Measuring the temperature of the radiation source and the ambient temperature is not sufficient to make clear decisions about the heating behaviour of the target itself. Therefore, the product temperature must be monitored and analysed, which is why Ceramicx uses IR temperature sensors from Micro-Epsilon. The measurement values provided allow conclusions to be made about the state of the finished product and help to control the heating system.

Micro-Epsilon’s thermoMETER CT sensors with external controller can be firmly installed into the heating systems during production.

The compact and robust design makes space-saving installation possible. The sensor head is robust against high temperatures, allowing the sensor to be fixed onto the heating element looking directly at the object to be heated. The measurement is performed on a non-contact basis, as direct surface contact via temperature probes would damage the component.

The infrared elements equipped with Micro-Epsilon sensors offer precise and repeatable process control of the end products. Therefore, the reject rate can be minimised while the controlled temperature regulation has a positive effect on energy consumption.

The thermoMETER CT-SF15 has a standard focus of 15:1 and an integrated 1 m cable.

Advantages of the sensors include the high temperature resistance of the CT sensor head, the flexible analogue output options and parallel digital output, precise and repeatable process control and monitoring of the object to be heated, along with improved energy use with efficient temperature control.

The thermoMETER CT sensors have a temperature measuring range of −50°C to +600°C and a response time of 120 ms, as well as being able to operate in high ambient temperatures of up to +180°C.
