SXY4S-19C-02-Z Liquid Level Adjustment Monitoring Instrument

It is an electric contact type liquid level measurement, display, and control instrument composed of liquid level measurement sensors, ultra pure ceramic electrodes, and display instruments. It uses a red green dual color light-emitting tube to simulate steam (red) and water (green) in the display, clearly indicating the position of the liquid level in the container, and has functions such as over limit alarm and output.

The monitoring device has the advantages of simple structure, intuitive display, reliable operation, low maintenance, and convenient diagnosis and troubleshooting. It adopts all electric signal transmission, which not only has a small delay, but also has no variation or scale error caused by mechanical transmission, and does not require error calculation and adjustment. The advantage of an electric contact level gauge is that it can adapt to variable parameter operation of the boiler. Under variable parameter operating conditions such as boiler start and stop, the instrument can accurately display the water level in the control room.

The liquid level monitoring instrument is suitable for measuring and controlling the liquid level of conductive liquids. Mainly used for monitoring the water level of boiler bubbles, high and low pressure heaters, deaerators, evaporators, condensers, DC boiler start-up separators, and other water tanks for liquid level measurement. But not suitable for flammable and explosive environments.

feature

The display part of the instrument adopts both analog display and digital display methods, which intuitively and instantly display the rise and fall of the water level.

The display points can be adjusted according to the user's needs6～19Set arbitrarily within the point range.

Each scale value can be set arbitrarily through panel operation, and the scale can be easily replaced according to the scale value, overcoming the disadvantages of poor universality, non interchangeability, and multiple requirements for spare parts specifications and varieties of old-fashioned instruments.

It has the functions of sound and light alarm for liquid level exceeding the limit and multiple types of alarm selection. The position of the alarm point can be set arbitrarily within the scale range of the ruler.

This instrument has the function of automatic judgment and tracking of water resistance. It can test each electrode separately and display the water resistance (vapor resistance) value of each point, allowing you to detect and judge whether the electrode is working normally in a timely manner, helping you decide whether the entire electrode needs to be cleaned or replaced, and providing adjustment parameters for the critical face value of the gas-liquid system.

It has strong fault tolerance. Due to the use of intelligent water level recognition technology, the instrument can still display the correct water level value in case of individual electrode abnormal operation, and immediately display the abnormal electrode on the panel ruler in a flashing form to remind you to perform maintenance and replacement, overcoming the defect of old-fashioned instrument electrodes that can only be detected after damage.

Strong resistance, advanced digital filtering technology is adopted for the input link, and the electrode state judgment function with hysteresis is used to greatly improve the reliability and resistance of the instrument. The output link adopts delayed alarm to prevent false alarm in the case of instantaneous strong interference.

The current output adopts a high linear output method (determined according to the set value of the scale range), avoiding the non-linear output of old-fashioned instrumentsDCSThe system is unable to transmit signals through a shielded end.

The self powered system adopts low voltage protection technology to overcome the phenomenon of battery damage caused by the old-fashioned instrument self powered mode.

The liquid level monitoring instrument can replace all old products of electric contact liquid level monitoring instruments. All interfaces are compatible with old instruments and can be directly replaced without any changes

SCFThe Type III calibrator is a matching calibrator specially designed and manufactured for liquid level monitoring instruments. It uses fuzzy control circuits internally to simulate the state of liquid and vapor, and performs functional checks on the liquid level monitoring instruments produced by our factory, including display, logic control and alarm circuits, drainage, noise reduction, and detection buttons. After verification, the instrument can be put into installation and use.
