Application Industries and Technical Value of Wireless Pressure Transmitters

Against the backdrop of rapid industrial digitalization and the development of the Internet of Things, pressure—one of the most fundamental and critical process parameters—is shifting from traditional manual inspection and wired acquisition toward wireless, digital, and remote monitoring. Wireless pressure transmitters have emerged as essential foundational sensing devices in this transformation.

By combining high-precision pressure sensing technology, low-power design, and wireless communication such as 4G and NB-IoT, Nexisense wireless pressure transmitters provide stable and reliable pressure data acquisition and remote monitoring capabilities for multiple industries.

What Is a Wireless Pressure Transmitter

A wireless pressure transmitter is a battery-powered pressure measurement device with wireless transmission and digital output. It converts pressure changes of the measured medium into standardized digital signals and uploads the data to cloud platforms or local monitoring systems via cellular or low-power IoT networks.

Compared with traditional wired pressure transmitters, wireless pressure transmitters require no cabling, making them especially suitable for dispersed measurement points, challenging installation environments, or long-term unattended applications.

Overview of the Working Principle

The typical working process of a wireless pressure transmitter includes the following stages:

• The pressure sensing unit detects the pressure of the medium

• Signal conditioning circuits perform amplification, filtering, and temperature compensation

• The control unit handles data acquisition and logical processing

• The wireless communication module uploads data periodically or event-triggered

• Local display and alarm functions operate simultaneously

Through this process, a complete closed loop of pressure data from the field to the platform is achieved.
