Measuring principle:
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, 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:
Using scenario:
The EJA115E with an integrated orifice plate differential pressure transmitter is suitable for measuring very low flow rates, providing a 4–20 mA DC signal corresponding to the measured flow. It can measure, display, or remotely monitor static pressure and features fast response, remote configuration, and self-diagnostic functions.
