EJA310E

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 an integrated circuit, effectively reducing hysteresis and minimizing the effects of temperature and static pressure. The sensor features fast response, self-diagnosis capability, and high stability.

Measuring Absolute Pressure with a Differential Pressure Structure

The EJA310E high-performance absolute pressure transmitter adopts monocrystalline silicon resonant sensing technology, suitable for measuring the pressure of liquids, gases, or steam. The EJA310E converts the measured pressure into a 4–20 mA DC current signal output and features fast response, remote configuration, and self-diagnosis capabilities.
