Intelligent differential pressure sensor differential pressure level sensor
The Intelligent differential pressure sensor and differential pressure level transmitter operate by detecting changes in capacitance values. Initially, the analog signal is converted into a digital signal through an Analog-to-Digital (AD) converter. This digital signal is then transferred to a microprocessor for processing. The microprocessor processes the signal and subsequently converts it into a 4-20mA analog electrical signal using a Digital-to-Analog (DA) converter.
The sensor utilizes a 16-bit single-chip core component, harnessing its robust capabilities and high-speed computing power to ensure the transmitter's quality. The design framework prioritizes reliability, stability, accuracy, and intelligence to cater to the increasing demands of industrial applications. To achieve this, the software integrates digital signal processing technology, offering exceptional anti-jamming capabilities, zero stability, zero automatic stability tracking (ZSC), and temperature automatic compensation (TSC) capabilities. These features collectively enhance the sensor's performance and reliability in industrial settings.
