EJA438E

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, which is then converted to 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 impact of temperature and static pressure. The sensor features rapid response, self-diagnosis capabilities, and high stability.

Single Flange with Capillary Tube

The EJA438E diaphragm-sealed pressure transmitter adopts monocrystalline silicon resonant sensor technology and is suitable for measuring the pressure and liquid level of high and low temperatures, high vacuum, high viscosity, and easily crystallizing media. It features fast response, remote configuration, and self-diagnosis functions.
