Product Description Product DescriptionThis wireless pressure transmitter belongs to the supporting product of oil-water well wireless monitoring system, and is suitable for pressure monitoring during production, storage, and transportation process of oil-water well. Adopts micro-power wireless communication mode, no wiring required, so installation becomes quicker, safer, and more convenient. In addition, there are matching wireless adapters that can convert many wireless pressure signals into MODBUS standard signals for transmission via Ethernet or serial port, which can help to access measurement control system more convenient and has a wide range of applications.2 Working PrincipleThe sensing element of this wireless pressure transmitter is a diffused silicon pressure sensor, and the Lora module is used for wireless communication. The sensitive chip uses integrated circuit technology to make a sensitive piezoresistance on a crystalline silicon wafer to form a wheatstone bridge as a sensitive device for force-electric conversion. When an external force is applied, the bridge loses its balance. When a constant current excitation power is applied to the bridge circuit, the pressure signal can be linearly converted into a millivolt-level voltage signal, amplified into a digital signal, and then sent by a wireless module to a host computer.

After installation, open the valve to confirm that there is no leakage, that is, the installation is qualified.7 Parameter Settings7.1 Set the instrument parameters by using the manual operator1) Select "Initialize" on the manual operator, enter the wireless channel, network, group number, and serial number to be set in the pop-up dialog window, and press the "Set" button to save.2) Place the magnet in the magnetic induction zone of the wireless pressure transmitter for 6 seconds. The transmitter resets and obtains the parameters from the manual operator.3) When you hear the "tick" sound of the manual operator, it means that the parameters of the wireless pressure transmitter have been set successfully.7.2 Use the buttons to set the instrument parameters.1) Press the Zero button, the instrument enters the setting mode and displays [01].2) Press the W2 button to enter the communication address setting state, and the modified digit flickers. At this time, press the W1 button to modify, and hex cyclically increments from 0-F. After the specified number is selected, press the W2 button to switch to the next digit. After the highest digit is set, press W2 to automatically exit the address setting and enter the next parameter setting item [02].3) Press the W1 button to switch parameter setting items. To make the parameters effective after the modification is completed, you must press the W1 button, switch to the [99] setting item, press the W2 button to enter the setting, and set its value to 1111. After setting, press the W2 button to confirm, the instrument will automatically restart, and the new parameters are saved.4) If you do not enter the [99] setting item, the previously modified parameters will not take effect, and automatically exit the setting state after the button times out.5) Parameter list description CodeCode description01Enable target Lora address to be specified, default 0.02Target Lora address, [01] is valid after enabling.03Regular data response waiting time.04Lora channel, subtract 11 from the channel calculated from the well name.05Lora Network ID.06Instrument Lora address, default 0xfffe, assigned by the coordinator.07Group code and serial number.08Maximum sleep time.99Save parameters, set to 1111 effective.8 Common Fault HandlingWhen the instrument cannot work normally, users can refer to the following table for simple maintenance. If the fault cannot be eliminated, please contact the manufacturer.
