(1) Intelligent chemical and mathematical temperature display accommodometer (three blocks) A, B and C circuits could respectively set temperature. According to the characteristics of spraying raw material by different manufacturers, by selecting different heating temperature, the different working requirements could be satisfied. The spraying temperature is generally set at 50 －75℃.
Three sensitive elements (Pt100) play the role of sensing and transmitting the temperature changes in the circuit.
(3) Overheat element: the overtemperature switch is installed on A and B heaters respectively
The radiator is installed with three solid-state relays (250V and 40A). When the temperature is not controlled, the heating power supply should be tripped and cut off.
