Wireless Pressure Transmitters: A Key Device Driving Industrial Pressure Monitoring Toward Wireless and Intelligent Development

With the rapid development of industrial automation, smart cities, and Internet of Things technologies, the limitations of traditional wired pressure transmitters in terms of wiring costs, installation flexibility, and remote operation and maintenance have become increasingly apparent. Wireless pressure transmitters are becoming an important direction for upgrading pressure monitoring systems.

Nexisense wireless pressure transmitters combine high-precision sensing technology with multiple low-power wireless communication methods to achieve real-time pressure data acquisition, wireless transmission, remote management, and intelligent alarms. They are widely used in fire protection, municipal infrastructure, water services, energy, and unattended operation scenarios.

What Is a Wireless Pressure Transmitter

A wireless pressure transmitter is a battery-powered, low-power, wireless digital output pressure measurement device. It converts the pressure of the measured medium into standardized digital signals and uploads them to cloud platforms or local monitoring systems via 4G, NB-IoT, LoRaWAN, and other wireless networks.

Compared with traditional pressure gauges or wired transmitters, wireless pressure transmitters require no wiring and offer flexible deployment, making them especially suitable for distributed measurement points, outdoor environments, and locations with limited power supply.

Working Principle Analysis

The basic working process of a wireless pressure transmitter includes the following steps:

1. Pressure Sensing
   The built-in laser-welded pressure sensor (typically diffused silicon or thin-film type) converts the medium pressure into a small electrical signal.

2. Signal Processing
   High-precision amplification, temperature compensation, and digital calibration circuits process the raw signal to ensure measurement accuracy and long-term stability.

3. Data Acquisition and Storage
   The MCU reads pressure data according to the configured sampling cycle and automatically stores data locally during network interruptions to prevent data loss.

4. Wireless Communication Upload
   Data is transmitted via GPRS, NB-IoT, or LoRaWAN networks using protocols such as TCP, UDP, MQTT, and CoAP.

5. Display and Alarm
   The local LCD screen displays real-time pressure values, and event messages are triggered when thresholds are exceeded to enable remote alarms.
