Measuring principle:
Monocrystalline silicon resonant sensors perceive measured parameters through changes in the vibration frequency of the resonant beam. When external pressure or density varies, the frequency of the H-shaped resonant beam on the monocrystalline silicon chip changes accordingly, and is converted into a standard electrical signal output via a 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.
Product positioning:
High pressure gauge reading
Using scenario:
The EJA440E high-performance pressure transmitter utilizes single-crystal silicon resonant sensing technology and is suitable for measuring the pressure of liquids, gases, or steam. The EJA440E converts the measured differential pressure into a 4–20 mA DC current signal output, featuring rapid response, remote configuration, and self-diagnostic capabilities.
