4-20ma Rs485 Digital Water Gauge Gas Differential Pressure Transmitter Sensor
4-20mA Rs485 Digital Water Gauge Gas Differential Pressure Transmitter Sensor Description:
4-20ma Rs485 Digital Water Gauge Gas Differential Pressure Transmitter Sensor is a fully isolated intelligent field measurement instrumentwith HART communication protocol optional, developed by our company.
The transmitter uses a fully isolated circuit technology design, and the sensor signals of the power supply box are isolated andprocessed, which greatly improves the stability and anti-interference ability of the whole equipment.
In addition to the three basic function buttons for adjusting the zero, range and zero pressure of previous smart transmitters,the transmitter is also designed to be used in combination with the three buttons M, S, and Z on the display. (You can set the
measurement range without adding pressure, modify the zero and full pressure values), set display engineering units, linearity,square root conversion, set damping time, and fixed current output.
The transmitter also has parameter data backup and recovery functions. When data is damaged, it can be restored online with three keys, with which can immediately back up the modified data.
The key functions of the transmitter can be adjusted by communication software or Hand-hold device from our company.
It is widely used in industrial applications with extreme chemical and mechanical loads field and high electromagnetic radiation
occasions.
4-20mA Rs485 Digital Water Gauge Gas Differential Pressure Transmitter Sensor Parameters:
| Signal output | Two-wire 4 ～ 20mA isolated DC signal superimposed HART, digital signal output, can output large current not exceeding 22mA. |
| Power supply | DC 12 ～ 45V; during HART communication, the power supply voltage range: 15.5 ～ 45VDC; General working voltage 24VDC. |
| Load range | In HART communication, the resistance in the power circuit is ≥250 ohms, and the power supply voltage is ≥15.5 volts |
| Communication distance | The diameter of the connecting wire is greater than 0.6mm, and the communication distance is about 1500 meters. |
| Display | Intelligent LCD, backlight 5 digits and a half digital display |
| Zero and span shift | The lower limit of the measurement range is not lower than the lower limit of the large measurement range, |
| and the upper limit does not exceed the upper limit of the maximum measurement range, that is, the working range does not exceed | |
| the sensor the limit value, zero position and range can be set at any corresponding point of 4 ~ 20mA. | |
| Zero pressure fine adjustment | use F3 key or code potentiometer knob to correct the error caused by transmitter installation |
| position change or zero position drift, and adjust the pressure of transmitter to zero pressure value. | |
