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.

Application examples:
  • secondary air
  • tertiary air
  • clinker cooler
  • exhaust
  • calciner

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).


GasTemp’s features in detail

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.
