Industry level water level water level display controller manufacturers display controller Price

Industrial water level display controller used in the factory - West Dingxing-controlled Engineering Limited provides product information. Level Level DXYK-3 industry display controller used by the display and control instruments and sensors of two parts. Measured medium is water, oil, acids, alkalis, industrial effluent and other conductive and non-conductive liquid. It is widely used in petroleum, chemical, power, metallurgy, light industry, pharmaceuticals, paper, food and water plant and sewage treatment and other fields of automatic control system, mainly for a variety of open and closed container and the underground tank, the water tank medium measurement and remote control, and in the central control room or instrumentation console monitor, display, alarm.

Magnetic field magnet wet (dry) sensor tube of reed to contact sticking or off, change the sensor output resistance is formed. By the display table will be converted into the corresponding resistance change of LED light-emitting diode light put out, so as to simulate changes in the level of the measured liquid level, when the level is not pull between the two wet (dry) reed, display table holding a position until the next wet (dry) reed action, to ensure that it does not appear dark area. Level alarm points are set in advance, when the level reaches a predetermined set point display table relay, relay contacts off, given the respective upper and lower limit alarm signal and outputs a control signal, in order to achieve level display and control automation.
