Intelligent input type level transmitter / material level meter

CR-Y20 series of intelligent input type level transmitter (sensor) Overview CR-Y20 series of intelligent input type level transmitter (sensor) is based on the measured hydrostatic liquid level of the liquid is proportional to the principle, the use foreign advanced isolated diffused silicon sensor or ceramic capacitive sensor, the static pressure is converted to an electrical signal, 16-bit microcontrollers through precise temperature compensation and linearity correction, converted into a standard electrical signal (usually 4 ~ 20mA). CR-Y20 series of intelligent input type level transmitter (sensor) used in petrochemical, metallurgical, power, pharmaceuticals, water supply and drainage, environmental protection systems, and liquid level measurement in various media industries. Compact structure, easy set-up and installation flexibility for users to easily use more convenient. 4 ~ 20mA, 1 ~ 5V, 0 ~ 10mA, RS485 communication, HART and other optional signal output required by the user. CR-Y20 series of intelligent input type level transmitter (sensor) in line with GB3836.4-2000 "electrical equipment for explosive gas atmospheres Part 4 Intrinsic Safety" i "" and GB3638.1-2000 "explosive gas environment electricity Part 1 General requirements ", proof mark: Exia Ⅱ CT6, it applies to 0, Zone 1 and Zone 2, and places of explosive gas mixtures containing Ⅱ A- Ⅱ Class C T1-T6 group, and by the national explosion-proof electrical product quality inspection center for testing qualified, made explosion-proof certificate number: CNEx08.1964. CR-Y20 series of intelligent input type level transmitter (sensor) Specifications Measuring range: 0.5 ~ 100m Accuracy class: ± 0.2% FS, ± 0.5% FS Media temperature: -20 ~ + 70 ℃ ambient temperature: -30 ~ + 60 ℃ Output signal: 4 ~ 20 mA or 1 ~ 5VDC supply voltage: 12 ~ 28VDC Wetted materials: 316 stainless steel and 1Gr18Ni9Ti Explosion levels: intrinsically ExiallC T6 flameproof ExdllC T5 Protection class: IP 67 Intrinsically safe parameters Ui: 28VDC, Ii: 93mA, Pi: 0.65W, Ci: 0.03uf, Li: 0mH 1, the transmitter can be vertical, inclined or horizontal installation in tanks, tank, should pay attention to prevent sediment buried or blockage of the diaphragm; 2. In addition to air conductivity cable for power and signal conversion, the main compensation for the introduction of air, pay attention when installing Do not hijack tight, bend over sharp; 3, the housing is mounted vertically on the tank top or near the stand, should ensure sunscreen breathable, wiring and installation location should be easy to adjust. 4, the product has been calibrated at the factory, the zero point is relative to atmospheric pressure, full points Henan Province is the relative pressure at one atmosphere. If you need to adjust the field can take the following methods: a field zero --- When the level is located in the least significant bit, the zero key "Z" click, automatically adjust the output current to 4mA. Site transfer full --- When the level is at the highest position, the tone is full key "S" click, automatically adjust the output current to 20mA. After adjustment, the transmitter cover should be tightened.
