    Product Description

    JC3051 Intelligent Differential Pressure Transducer Overview:

    Jc3051 intelligent differential pressure transducer is a new type of instrument researched and developed by our company according to international advanced technology combined with many domestic technologies. This instrument adopts micro-processing technology for temperature characteristic and non-linear compensation, thus having greatly enhanced the measurement accuracy of the instrument, improved the temperature characteristic and expanded the turndown ratio. Besides, intelligent functions can be added, which further meets the requirements of high reliability and high stability of the instrument at the industrial sites. The adoption of digital technology in the capacitive pressure / differential pressure transducer not only ensures high reliability of the instrument and other superior performance, but also realizes the remote digital connection between the intelligent instrument and the control room to ensure rapid and reliable communication. The control room can remotely enquire into or make a real-time configuration of the transducer. The sensitive elements of this intelligent transducer are the same as those of general JC61151 series of capacitive transducers and featured by stability and reliability.


    JC3051 Intelligent Differential Pressure Transducer Features:

    * High accuracy

    * Good stability

    * Small size, light weight, solid and vibration resistant

    * Good compatibility, compatible with products of other companies in line with HART protocol

    * Support the user to use handheld unit 272 / 275 or PC for software debugging and for real-time configuration of the instrument during its running.

    * Can conduct intelligent linearization for pressure signal to ensure higher accuracy of measurement.


    JC3051 Intelligent Differential Pressure Transducer Working Principle:

    The intelligent PCB integrates converting circuit and processing circuit into one circuit using advanced IC and SMT technology. The micro-processor of the transducer controls the A / D and D / A converting module and performs digital communication and self-diagnosis function. When working, the micro-processor controls the A / D converting module for sampling conversion of the analog signals from the sensitive elements and converts them into digital signal so that the micro-processor can process it, including signal linearization, temperature compensation, engineering unit conversion etc. The micro-processor can also complete sensor characterization, measuring range, damping time, and other functions. E2PROM stores all the configurations and tuning parameters. Because the memory is a non-volatile memory (NVM), the parameters stored will not be lost in case of power failure. The PC working station or personal digital assistant (PDA) is used to configure and test the parameters or complete communication with any upper system supporting HART protocol. HART protocol uses industrial standard BELL202 frequency shift keying (FSK) technology to realize communication with the 1200HZ2200HZ digital signals overlapped on 4 ~ 20mA signal. The frequency signal during communication will not disturb the process signal. This intelligent capacitive transducer can perform online real-time self-diagnosis. The transducer has a presetting value of 3.9mA before delivery if it has 21mA or 3.9mA output.
