Flue gas temperature monitor
April 2014
Temperature Measurement
ASSTech’s flue gas temperature monitor from the Jumo heatTHERM-AT range has new, enhanced features. The probe element now has an external diameter of 6 mm (previously 4,2 mm). This makes the thermostat considerably more robust and meets the DIN EN 14 597 requirements of a response time of less than 45 seconds in air.
The thermostat now has a maximum probe temperature of 600°C, which allows operation in older boiler systems with large variations in maximum temperatures. In such cases, high temperature values may be produced, in particular during the ignition phase. With its streamlined design, the heatTHERM-AT ATW is also suitable for monitoring flue gas temperatures in modern plastic flue pipes.
Jumo has increased the control range, and users can select temperature ranges from 20 to 280°C, according to the application. The classic application – flue gas temperature monitoring in a chimney – has been taken into account, with calibration at around 100°C, at which point the greatest degree of accuracy is achieved. In addition, it is possible to check the set switching temperature through the inspection window in the case lid.
