此前, The oil level of 803 type thermostat technical parameters

Transformer temperature controller is mainly composed of elastic element, capillary tube, bulb and the micro switch. Package when heated, when the bulb temperature heat medium volume increment, produced by thermal expansion through the capillary is passed on to the elastic element, make the elastic element produces a displacement, the displacement of the measured temperature after amplified by institutions indicates that work and drive the micro switch, to control the into or out of the cooling system.

　　BWY( WTYK) - 803 a type 1, normal working conditions: - 30 ~ + 55 ℃, measuring range: 2-20 ~ + 80 ℃ 0 0 0 ~ + 100 ℃ ~ + 120 ℃ ~ + 150 ℃, indicating accuracy: 1. 4, control performance: (level 5 1) Set range: full range of adjustable ( 2) Setting precision: + 3 ℃ ( 3) Switch: 6 + 3 ℃ ( 4) Rated power: AC 220 v / 3 A ( 5) Standard Settings: K1 = 55 ℃ K2 = 65 ℃ K3 = 80 ℃ 4, installation and use: BWY - The oil level of 803 type thermostat: switch setting: BWY - 803 factory standard value of K1 = 55 ℃; K2＝65℃； K3＝80℃。 If need to change the set value, it must open the table cover, loosen the switch fixed screw, to set the red needle throw to the desired set point, then tighten the set screw, as is in the table cover.
