ZWYG-2087 On-Line Suspension Concentration Meter/Sludge Concentration Meter Chapter Overview ZWYG-2087 Suspension Concentration Meter is a new generation of all Chinese microcomputer type instruments, with full Chinese display, Chinese menu operation, full intelligence, multi-function , high measurement performance, strong environmental adaptability and other characteristics. It can be widely used in wastewater treatment plants to accurately measure the concentration of sludge in various water samples.
Basic functions and features Notepad function: faithfully records the operating conditions of the instrument and the time of occurrence of the alarm, facilitating management.
History curve and digital recorder function: The secondary meter automatically stores the secondary measurement data every 5 minutes and can continuously store the monthly sludge concentration. On the screen, both the “historical curve†display and the “timed fixed point†query are provided. The “historical curve†reflects the trend and process of water quality as a whole, which is conducive to finding problems and solving problems. "Timed fixed point" function will get the measured sludge concentration at a specific point and time.
Digital clock function: Displays the current time and provides a time reference for the digital recorder function.
Backlight function: can be used in dimly lit or completely dark environment, according to temperature changes, automatically adjust the contrast to clear, in order to meet personal habits.
Anti-program fly dead: Watchdog program to ensure that the instrument will not crash, which is the basic requirements of online instruments.
Output current setting and check function: Manual current source function, which can check and arbitrarily set the output current value, which is convenient for detecting the recorder and the lower unit.
All-intelligent: ZWYG-2087 Chinese online suspended substance concentration meter adopts high-precision AD conversion and single-chip micro-processing technology, and can complete various functions such as sludge concentration measurement, automatic range conversion, and instrument self-test.
High reliability: The components are integrated into the block circuit board without complex function switches, adjustment knobs and potentiometers.
Strong anti-interference ability: The current output adopts photoelectric coupling isolation technology, which has strong anti-interference ability and realizes remote transmission. Has good electromagnetic compatibility.
Waterproof and dustproof design: protection and other IP65, suitable for outdoor use.
RS485 communication interface: It can be easily connected to the computer for monitoring and communication.
All Chinese display, friendly interface: the use of high-resolution dot matrix graphic LCD module, all the data, status and operating tips are Chinese display, there is no manufacturer-defined symbols or code.
Simple menu structure, text-based person table dialogue: compared with the traditional meter, ZWYG-2087 features a lot of increase, due to the use of a separate menu structure, similar to the operation of the computer, use more clear and convenient. It is not necessary to memorize the operation steps and the operation sequence. You can operate without the instructions and follow the on-screen instructions.
Simultaneous display of multiple parameters: Simultaneous display of sludge concentration, output current, time and status on the screen. The main display shows the sludge concentration value in 10x10mm format: eye-catching and visible distance; 3 sub-displays display output current, status, day, month, day, hour, minute and second in 5x5 specifications to meet the user's different usage habits and provide The time base of the second table.
