Meokon-Explosion-Proof-House-with-IP67-Industrial

Functional parameters:
1. Scope of use: liquid, gas and steam.
2. Signal output: two wire system 4 ~ 20mA isolated DC signal superimposed HART digital signal output, linear or square root output can be selected, the maximum output current is not more than 22mA.
3. Power supply: DC 12 ~ 45V; HART communication, power supply voltage range: 15.5 ~ 45V DC; General operating voltage: 24V DC.
4. Load range: HART communication, the resistance in the power circuit is more than 250 Europe, the power supply voltage is more than 15.5 volts.
5. Communication distance: the diameter of the connecting wire is greater than 0.6mm, and the communication distance is about 1500m.
6. Display device: smart LCD liquid crystal backlight 5-digit display; Use a combination of
LCD The M, Z, and S keys on the liquid crystal display, the display can be cyclic or fixed display: KPa, mA, %, mmH2O, MPa, Pa, bar, ATM, PSI, Torr and other engineering units, can be implemented without pressure to modify the measurement range (passive migration), set the fixed current output, modify the damping time, set linear, square output and backup and restore data and other functions.
7. Zero and range migration: the lower limit of the measuring range shall not be lower than the lower limit of the maximum measuring range, and the upper limit shall not exceed the upper limit of the maximum measuring range, that is, the working range shall not exceed the limit of the sensor. The zero and range can be set at any corresponding point from 4 to 20mA.
8 zero pressure fine tuning: use M+Z button to clear the zero, correct the transmitter installation position change or zero drift caused by the error, the transmitter pressure adjusted to zero pressure value.
9 resistance value: electronic damping adjustable range of 0 ~ 32 seconds.
10. Fault alarm: When the fault is detected by the self-diagnosis program, the analog output is higher than 20.8mA or lower than 3.9mA.
11. Data recovery: when the data is damaged, the damaged data can be recovered by three keys.
12. Temperature compensation: the computer collects temperature data and sends it to the transmitter for temperature compensation.
13. Temperature indicator: indicates the ambient temperature value of the transmitter.
14. Operating temperature: electronic circuit: -40 ~ +85ºC, with LCD LCD: -30 ~ +80ºC; Sensitive element (filled with silicone oil) : -40 ~ +104ºC;
15 storage temperature: -45 ~ +90ºC.
16. Safety protection: AND circuit protection design, anti-static impact, surge current, overload protection function is powerful.
