GASTEMP™
Looking for a smart solution for measuring gas temperatures? The remedy: GASTEMP for precise measurement of gas temperatures.
high precision
The measuring accuracy of < 3 °C is the basis for optimised process control.
short response times
Acoustic measurement allows short response times of < 1 sec.
large measuring range
The large measuring range of 0—900 °C (larger on request) permits the use in a wide variety of applications. One device—many application areas.
robust material
The use of modern, chemically inert ceramics ensures safe application in difficult atmosphere and prevents the sensor element from corrosion.
no interference by heat radiation
The special measurement method eliminates any interference by radiating heat. GASTEMP determines the actual gas temperature.
easy connection
Coming with an industrial standard 4—20 mA interface, the system can be connected to the PLC or other process interfaces easily.
Acoustic measurement of gas temperatures
The efficiency of many processes in chemical, thermal and process engineering is determined by gas temperatures. In order to optimise these processes by means of closed-loop controls, the gas temperature needs to be measured promptly and precisely. The “classical” thermo couple method reaches thermal equilibrium with the gas to be measured with a long delay and is interferred by heat radiating surfaces.
In contrast, the speed of sound in gases depends on the gas temperature only. The newly developed ceramic sensing element measures the speed of sound in gas quickly and very precisely, and thus directly determines the gas temperature with the same accuracy and high speed (500—1 000 msec).
