Working principle of wireless pressure transmitter

A wireless pressure transmitter is a device used to measure and transmit pressure signals. Its working principle mainly includes the following steps:

Pressure measurement:

A wireless pressure transmitter is usually equipped with a pressure sensor inside, which can be a strain gauge type, a piezoresistive type, a ceramic capacitor type, etc. The pressure sensor converts the pressure of the measured medium into an electrical signal or other forms of signal.

Signal conversion:

The signal output by the pressure sensor is often an analog signal (such as a voltage or current signal), which needs to be amplified, filtered and linearized by a signal conditioning circuit to obtain a signal that can be used for digital processing.

Signal digitization:

The conditioned signal will be converted into a digital signal by an A/D (analog-to-digital converter) for subsequent data processing and wireless transmission.

Wireless data transmission:

The digital signal is sent to the receiving device or control system through a wireless communication module (such as LoRa, Zigbee, NB-IoT, Wi-Fi, Bluetooth, etc.). The specific wireless communication technology selection depends on the application requirements, such as transmission distance, data transmission rate and power consumption.
Power management:

Wireless pressure transmitters are usually powered by batteries, but other low-power power sources can also be used. The power management system optimizes energy consumption to extend the battery life.

Data processing and display:

After the receiving device receives the wirelessly transmitted data, it can further process, store or display it for remote monitoring and control.

The advantage of wireless pressure transmitters is that they do not require wiring, are suitable for use in complex environments or inaccessible locations, and can monitor pressure changes in real time through remote transmission.

Description

Thank you for using our company's single crystal silicon series intelligent pressure/differential pressure transmitter. The transmitter adopts a modular design with a microprocessor as the core and advanced digital isolation technology in circuit design, which makes the instrument highly anti-interference and stable. At the same time, it uses digital compensation technology to compensate for temperature and static pressure, which improves the measurement accuracy and reduces temperature drift. It has the characteristics of good long-term stability, high reliability, strong self-diagnosis ability, etc. In terms of structure, users can easily configure, set and calibrate the transmitter through the HART communication handheld operator, the knob outside the shell and the buttons on the display.

When you receive the pressure transmitter, carefully inspect the packaging box for any damage during transportation. If the box is damaged, notify the shipping department and provide a report to the manufacturer or distributor. Unwrap the packaging tape and check whether the ordered parts are complete. Be careful not to discard useful devices and accessories with the packaging materials. Do not return any parts to the factory without first contacting service. The model number and main technical specifications of the instrument are marked on the nameplate of the casing. Please be sure to check whether it matches the specifications when you originally ordered. If you encounter problems with your pressure transmitter, please check whether the installation and operation procedures are correct. Make sure your settings and adjustments are consistent with the manufacturer's recommendations.

The correct position of the transmitter process pipe depends on the medium being measured. In order to select a reasonable installation location, the following points should be considered:
1) Corrosive or overheated media cannot be in direct contact with the transmitter;

2) Prevent slag from depositing inside the pressure tube;

3) Use the pressure tube as short as possible;

4) The hydraulic height in the two pressure pipes should be balanced;

5) The pressure pipe should be installed in a place with small temperature gradient and fluctuation;

When measuring gas pressure, it is required to install a pressure-inducing pipe connected to the process pipeline within 45° of vertical upward or vertical upward direction. The transmitter should be installed above the side pressure port to allow liquid to be discharged into the process pipeline. When measuring liquid pressure, it is required to install a pressure-inducing pipe connected to the process pipeline in the horizontal direction or within 45° downward in the horizontal direction. The transmitter is installed under the pressure port on the side to allow gas to be discharged into the process pipeline.

Specification

Product maintenance
1. All connections of the intelligent transmitter cannot be loosened or disassembled at will.
2. The intelligent pressure transmitter needs to be placed and handled gently to prevent damage to the diaphragm and other accessories. If it is damaged and needs to be repaired, it should be returned to our company.
