Đầu báo nhiệt chống nổ (70ºC)

Đầu báo nhiệt chống nổ (70ºC) Siemens

Thông tin chi tiết

Response behavior immune to deceptive phenomena with rapid and slow increases
in temperature
Intelligently designed differential characteristics
Maximum temperature alarm activation with quality thermo sensor
Reliable heat detector for demanding requirements:
– DT1102A-Ex: Heat detector for high ambient temperatures (up to +70 °C)
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.
– Built-in alarm indicator provides on-site signaling of alarm.
Application
– For the monitoring of explosion-hazard areas of zones 1 and 2 where in the event of
fire, a rapid increase in temperature can be expected, or other types of detector cannot be used due to operational reasons.
