EJX910A

Monocrystalline silicon resonant sensors perceive measured parameters through changes in the vibration frequency of the resonant beam. When external pressure or density changes, the frequency of the H-shaped resonant beam on the monocrystalline silicon chip changes accordingly, and is converted into a standard electrical signal output by the microprocessor. This technology employs a dual Wheatstone bridge design combined with integrated circuits, effectively reducing hysteresis and minimizing the effects of temperature and static pressure. The sensor features fast response, self-diagnostic capabilities, and high stability.

The EJX910A high-performance multivariable transmitter uses a single-crystal silicon resonant sensor and can output measured differential pressure, static pressure, process temperature, and calculated mass flow. It supports multiple protocols such as HART, FOUNDATION Fieldbus, and RS485 Modbus.
