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, 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.
Product positioning:
Standard Differential Pressure
Using scenario:
The EJA110E high-performance 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 EJA110E converts the measured differential pressure into a 4–20 mA DC current signal output, allowing for measurement, display, or remote monitoring of static pressure. It features rapid response, remote configuration, and self-diagnosis functions.
