EJA110 differential pressure transmitter
EJA110A differential pressure transmitter adopts single crystal silicon resonant sensor technology
Product details
EJA110A differential pressure transmitterAdopting monocrystalline silicon resonant sensor technology. Monocrystalline silicon does not exhibit hysteresis in response to changes in pressure or temperature, making it an ideal material. Monocrystalline silicon resonant sensors minimize the effects of overvoltage, temperature changes, and static pressure, providing unparalleled long-term stability.
