Thermometers
Explosion-proof electric contact bimetal thermometer

外壳采用铝合金制成,通过铝合金外壳把仪表内可能产生火花、电弧的电路与表壳外爆炸性气体混合物隔开,从而达到隔爆的目的。 WSSX series explosion-proof electrical contact bimetal thermometer housing is made of aluminum alloy. The aluminum alloy housing is used to separate the circuits that may generate sparks and arcs from the explosive gas mixture outside the case to achieve the purpose of flameproof.
The performance of explosion-proof electrical contact bimetal thermometers complies with BG3836.1-2000 "Explosion-proof electrical equipment for explosive gas environments-Part 1: General requirements" and GB3836.2-2000 "Explosion-proof electrical equipment for explosive gas environments-Part 2: Flameproof type Standard for electrical equipment "d". zzyfwh.com
Explosion-proof electrical contacts Bimetal thermometers have electrical contacts-mechanical electrical contacts. When the temperature of the measured medium changes, the thin shaft on the free end and the steering transmission mechanism drive the pointer and the moving contact to rotate, and the temperature change value is indicated on the dial. When it is in contact with the fixed contact (upper and lower limit contact) Point) at the moment of contact or disconnection, the relays and contactors in the circuit system are moved to achieve the purpose of automatic control and alarm.
是利用绕制成螺旋管状的双金属片一端被固定,另一自由端与指针连接,随着温度的变化而转动,并带动指针旋转指示温度的单针式指示温度计。 The WSSX series explosion-proof electrical contact bimetal thermometer is a single-needle type indicator that uses one end of a bimetal sheet that is made of a spiral tube to be fixed, and the other free end is connected to a pointer. thermometer. It is the temperature measurement of liquid, steam and gas medium and solid surface in the range of -80 ~ + 500 ℃ in the process of the presence of explosives such as carbides in the production sites of petroleum, coking, chemical, pharmaceutical and other enterprises.
