Heat differential maximum detector with limit value technology for Ex Zone 1. Designed for use in areas where rapid heat development due to flames is to be expected. Robust heat detector with 2 temperature sensors also for use in industrial areas. Heat detector with intrinsically safe electronics for operation in potentially explosive areas. Connection to the BMZ via the TCM and a Zener barrier (item no.: 33084). The barrier must be installed according to the manufacturer's instructions and outside of the Ex area.
