The most important measurement quantity in chemical engineering is temperature. The quality of the end products depends directly on the precise thermal process management. Therefore, more and more manufacturers of process thermometers take advantage of the Pt sensors in thin-film technology from Heraeus Sensor Technology.
The shifting of the application limit for Pt sensors in thin-film technology from 650°C to 850°C represents a milestone in process measurement technology. Investigations have shown that the Pt sensors developed by Heraeus Sensor Technology also conform to the requirements of process technology in continuous operation. The versatile film structure safely protects the measurement element against the pressure load in mineral insulated resistance thermometers.
The resistance temperature sensor HD 421 in platinum thin-film technology from Heraeus Sensor Technology is an alternative to thermocouples with their low output signals which are sensitive to interference and with the ageing phenomena that is already noticeable at temperatures above 800°C.
Platinum provides stability
The reliability, response characteristics and standardised, easily evaluated output signal make a change of system by the equipment installer a sensible decision. In addition there is the resistance to shock, impact and typical plant vibrations. Here, the Pt sensors of the HD series from Heraeus Sensor Technology easily shrug off vibrations in the typical process frequency range from 10 Hz to 2000 Hz and accelerations of up to 100 g.
The specialists at Heraeus Sensor Technology are agreed that with their stability and dependable signals Pt temperature sensors from their company will in the future make a contribution to reducing maintenance costs and downtimes everywhere in chemical engineering, in machine and plant construction and in power stations.
