Description of Intelligent differential pressure sensor
differential pressure level sensor
Intelligent differential pressure sensor differential pressure
level transmitter will cause changing of capacitance value, analog
signal convert to digital signal via AD and then being transfered
to microprocessor, processed by microprocessor then convertted to
4～20mA analog electricity signal via DA.
Parameter of Intelligent differential pressure sensor differential
pressure level sensor
| Output | two –wire 4-20mADC |
| two –wire 4-20mA with HART |
| Power supply | supply voltage 24VDC |
| 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) |

Feature of Intelligent differential pressure sensor differential
pressure level sensor
It has reverse protection and current limiting protection circuit.
When the positive and negative poles are reversed during
installation, the transmitter will not be damaged. Solid-state
structure, no moving parts, high reliability, long service life,
easy installation, simple structure, economical and durable.
