Jc63051 Differential Pressure Transmitter 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.

Tips for Type Selection
* In order to guarantee safe and reliable operation of the transducer, it is recommended that the three-valve manifold should be installed between the point to be measured and the transducer to ensure that the medium to be measured is slowly and evenly applied on the positive and negative chambers.
* During installation, it is recommended that pressure connections on both ends should be located above the horizontal line so as to minimize the influence of the installation position on the product.
* During type selection, please note that the static pressure to be measured shall be less than 20MPa and the overpressure to be applied on the positive and negative chambers shall not exceed the specified value of the product.
* As an additional function code for type selection, the code "E" for intrinsically safe explosion-proof type Ex iaIICT6 denotes that power source must be supplied via safety barrier.
* For other special requirements, please discuss with us and clearly indicate them in the order.
