Applies only to models 204 and 206.
Invasive Pressure Specifications
Characteristic Specification
Transducer Type Strain-gauge resistive bridge, or HP quartz (with HP Option).
a
a.Transducers with 40 µV/V/mmHg sensitivity are not compatible.
Transducer Excitation Impedance
Range
200 to 2000 Ω
Transducer sensitivity 5
µV/V/mmHg
Excitation Voltage 4.85V Pulsed dc @ 181 Hz
b
b.Duty factor depends on transducer impedance. For 200 to ~900 Ω, duty factor is ≈ 11%. Above ~900 Ω, the
duty factor increases to ≈ 91%.
