Because of the influence of ultra high or ultra-low temperature, the sensor causes drift and hysteresis, it is normal-on and damaged. FBT high temperature / low temperature series proximity sensor, mainly for the environment beyond the normal working temperature range (-25-70 C), from -40 to +250 C to provide reliable detection way, widely used in steel blast furnace, railway track, power stations, aircraft, boilers, outdoor advertising and other commercial industry.
