    notes
    [1]specification refers to the internal amplifier, not on the Housing
    [2]with helium flow
    [3]zero-based balancing line, determined using the method of least squares
    [4]for output range supply voltage up to 10 V must be at least 24 V DC. At low bias voltage of the sensor, no negative output range is usable up to-10 V.
