1, DPharp digital sensor: DPharp digital sensor, even when the process pressure has not changed when the process pressure does not change, still constantly output the frequency signal. So if a sensor failure occurs, the transmitter can be the first So if the sensor fails, the transmitter can detect it at the first time and will not mistake the sensor failure as the process pressure has not changed. 2, dynamic compensation and higher accuracy: DPharp digital sensors have the ability to simultaneously measure differential pressure / static pressure / temperature The ability to dynamically compensate the measured value based on real-time data, eliminating the effects of temperature changes and static pressure changes, and achieving higher accuracy. to achieve higher accuracy. 3, Composite sensing function: The composite sensing function of DPharp sensor can be measured by a single transmitter differential pressure and static pressure two process variables, without the need to set up separate transmitters, saving up to 20% of the capital expenditure (CAPEX). (CAPEX). 4, signal curve characterization: EJA-E series transmitters have a 10-segment signal curve characterization function, suitable for compensating non-linear applications of 4 ~ 20mA analog output signal. It can be used in all applications such as tank measurement and flow measurement where the correspondence between input pressure and output signal is clear, making the measurement more flexible and convenient. 5, diagnostic functions: EJA-E series transmitters have 40 self-diagnostic functions, two of which are its unique features. The first is the patented Back-Check technology, which confirms and detects the correctness of the calculation through real-time backward calculation. Second, DPharp is an active sensor, which continuously outputs a corresponding signal even if the input pressure has not changed. When the sensor signal is interrupted, the transmitter is able to detect the sensor failure at the first time. While passive sensors in the absence of signal output, can not determine whether it is due to the pressure did not produce changes or sensor failure. 6, overpressure protection: not only the robust design of the DPharp sensor itself can resist the effects of overpressure, in addition, the internal mechanical design of the diaphragm box further provides overpressure protection function, so that the transmitter from, for example, incorrect valve operation and unexpected pressure surges and other overpressure events, or even damage. 7, Functional safety: EJA-E series transmitters are designed and certified in accordance with IEC61508:2010 (Part 1~7) and IEC61511:2004 (Part 1~3) standards, meeting SIL 2 safety requirements for single units and SIL 3 safety requirements for redundant use. Using EJA/EJX series transmitters, one can meet the production application and safety requirements without redundant configuration. 8, independent third-party certification: EJA-E series transmitter performance and reliability has been certified by international independent third-party organizations TÜV Rheinland and EXIDA.
