EJA130E

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, 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.

High Static Pressure Differential

The EJA130E high-static-pressure differential pressure transmitter utilizes monocrystalline silicon resonant sensor technology and is suitable for measuring the flow, level, density, and pressure of liquids, gases, or steam. The EJA130E converts the measured differential pressure into a 4–20 mA DC current signal output, and it can measure, display, or remotely monitor static pressure. It features rapid response, remote setting, and self-diagnosis capabilities.
