Technical description
1485
Application
For the monitoring of explosion-hazard areas of zones 1 and 2 with a mAximum ambient temperature of
70 °C. It is the right heat detector for locations where large temperature fluctuations and high tempera-
tures occur. It continuously measures the ambient temperature and reacts if defined mAximum values
are exceeded.
The base DB1101A must be ordered separately.
Function
The detector measures the ambient temperature with one NTC thermistor and the detector housing
temperature with another NTC thermistor. In this way the detector can rapidly and differentially evaluate
an increase in temperature independent of the starting temperature.
