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

11%. Above ~900 Ω, the duty factor increases to
≅
91%.
