EJA310A absolute pressure transmitter

EJA310A absolute pressure transmitter Abstract: EJA310A series using silicon resonant sensor technology. Monocrystalline silicon pressure or temperature changes for the absence of hysteresis, is ideal material. Silicon resonant sensor overvoltage, temperature changes and static pressure influence reduced to a minimum, providing unparalleled long-term stability.
