Product Description
Introduction of capacitive differential pressure transmitter :
HT3351 capacitive differential pressure sensor transmitter, through the pressure difference or pressure difference to change the capacitance value of the sensor, the resulting analog signal through AD conversion, into digital signal sent to the microprocessor. The output digital signal is calculated and processed by the microprocessor, and is sent to the current control circuit after digital-to-analog conversion, and converted into 4 ~ 20mA analog current signal output. Suitable for small range liquid, gas measurement. There are inherent advantages for liquid pressure measurement in the smile range.
Product Features of capacitive differential pressure transmitter:
1. The transmitter adopts stainless steel structure design, compact structure, easy installation.
2. After strict temperature compensation and aging screening, to ensure stable and reliable performance.
3. The electrical interface can choose plug-in or directly connected.
Range:
| Output | Analog output: two –wire 4-20mADC |
| Digital output: two –wire 4-20mADC and superimposing variable digital signal accord with HART | |
| Power supply | supply voltage 12.5-45VDC |
| Limit load | Max load resistor Rmax in loop decided by the supply voltage, see the below drawing. HART PROTOCOL require the load resistor not less than 250Ω,not more than 600Ω |
| Communication distance | Max. 1.5Km, multi-address communication can connect 15 smart transmitters Max. |
| Display | 4 digital display,5 digit LCD display, pointer type. |
| Explosion-proof | ExiaIICT5;explosion suppression type |
| Zero offset | Can positive transfer or negative transfer, but can not overstep the utmost value |
| Temperature | ambient temperature -40-85℃(When choose LCD : -20-70℃) |
| Medium temperature | -40～104℃ |
| Static pressure and single side overpressure | 3.45KPa(absolute pressure)～31.2MPa(gauge pressure) |
| Relative humidity | 5～98%RH |
| Run-up time | less than 5 sec. |
| Capability change | Less than 0.16cm3 |
| Damp adjust | 0.20～25 second |
| Malfunction alarming | If occur malfunction, automatism diagnose function will output 3.9 or 21.0mA |
| Configuration protection | To avoid the datas are modified random, can utilize software or protect switch lock the record data |
