One. Product overview

WSSX series explosion-proof electric contact bimetallic thermometer shell adopts aluminium alloy made by aluminum alloy shell inside the meter may produce a spark, arc circuit and watchcase explosive gas mixture is separated, so as to achieve the goal of flame-proof.
Explosion-proof electric contact bimetallic thermometer product performance in line with the BG3836.1-2000 "explosive gas environment with explosion-proof electrical equipment Part 1: general requirements and GB3836.2-2000 "explosive gas environment with explosion-proof electrical equipment Part 2: "d" flameproof electrical equipment "standard.
Explosion-proof electric contact bimetallic thermometer with electric contact device, mechanical electric contact.When the temperature measured medium, fine axis and steering transmission mechanism on the free end turns pointer and the moving contact, on the dial indicates that the change in temperature, when with the fixed contact (upper and lower limit contact) contact or disconnect the instantaneous, relay and contactor in the circuit system action, in order to achieve the purpose of automatic control and alarm.
WSSX series explosion-proof electric contact bimetallic thermometer is the use of round made the bimetallic strip end of the spiral tube are fixed, the other free end connected to the pointer, as the change of temperature and rotation, and drive the pointer indicates the single needle type temperature indicating thermometers.Is oil, coking, chemical industry, medicine and so on in the process of enterprise production site such as carbide explosives each - 80 ~ + 500 ℃ within the scope of liquid, steam and gas medium and the temperature measurement of solid surface.
