A principle, properties and USES
Principle performance: is when be controlled object temperature change make the thermostat temperature area of the working medium produces the corresponding heat bilges cold shrink physical phenomena (working medium volume change), and heat department connected together film box produce expansion or contraction, through the lever principle, drive switch on-off action, to achieve the purpose of control temperature. WG series liquid expanding type temperature controller with accurate temperature control and it is stabilization and reliable, open stop temperature difference is small, control temperature regulating range, overload current such as the performance characteristics.
USES: mainly used in household electrical appliance industry (shower, drum washing machine, steam air heater), electric equipment (stainless steel auto water boiler, embedded electric oven, electric fryer, food machinery, medical equipment), refrigeration industry (kitchen freezers ?
Second, the technical parameters
1, electrical properties, 16 (3) A - 250 v ~ 10 (1.8) A - 400 v ~
2, disconnect temperature: according to the user's requirements, design temperature range (- 35 ℃ ~ + 320 ℃)
3, product life: > 100000 times
4, electric strength: AC2000V / 1 min
5, normal insulation resistance: was 100 m Ω
6, contact resistance: acuities 50 m Ω
7, tide state insulation resistance: or 10 m Ω
8, temperature response rate: acuities were 1.0 ℃ / min
9, minimum current: 200 ma
Three, the matters needing attention
1, the user must be according to the characteristics of their products, the temperature control, and puts forward the order type and specification.
2, the thermostat installation, heat pipe as team that was against temperature control surface, in order to achieve the purpose of accurate temperature control.
3, installation shall not will heat pipe pressure deformation, lest affect its performance.
4, keep conductive gas or conductive material into the thermostat or pollution in thermostat surface so as not to affect the electrical insulation performance.
5, mounting bracket of the M4 machine wire don't too long, otherwise it will damage the thermostat performance.
6, switch box is electric ceramic thing to be handled with care to avoid damage.
7, capillary bending radius can not less than 5 mm.
