FAST AND PRECISE TEMPERATURE MEASUREMENT Inline temperature probes are used, when the temperature has to be measured accurately and fast in the production process for safety reasons or to control the system. These are installed directly in the machine or in production arms and measure the surface temperature or the temperature of the medium by contact. For this reason, these temperature sensors are not only exposed to various and sometimes high temperatures but also to other challenging environmental conditions such as humidity, steam, pressure, dust, emissions or chemically aggressive media. Technical requirements Inline temperature probes Since inline temperature sensors are used to control the system, they must measure accurately and have a fast response time. At the same time, they must be able to withstand high temperatures at least on the part in contact, i.e. at the measuring tip. Used is often a special design: cross-band sensors. Because the most accurate surface temperature measurements are physically complex, they require a highly developed and sophisticated sensor head design, such as that of crossband sensors. Two thin thermobands crossed over in the sensor head measure a thermoelectric voltage that quickly and accurately represents the surface temperature. Due to the filigree design of the measuring head, only very little heat is extracted from the measuring point, so that the measurement error is negligible. The low thermal mass of the thermal ribbons in the measuring head ensures particularly short response times when measuring the surface temperature.
