BP (Blood Pressure) Amp

Input

• Connection type: 6-pin Tronomed brand Spacelabs 0440-01- LX transducer cable with a 4-pin transducer connection cable
• Safety: Approved to IEC60601-1 BF (Body protected) standard
• Input impedance: >10 kΩ at 400 Hz AC
• Input isolation: Transformer isolation (AC bridge operation)
• Isolation rating: 4000 V AC_rms for 1 minute
• Amplification ranges: 50 to 250 mmHg full scale in 3 steps (combined PowerLab and BP Amp)

• User offset: Arbitrary scale offset (for example, –50 with 100 mmHg range gives –50 to 50 range)
• Frequency response: –3 dB at 50 Hz using PowerLab E series –3 dB at 55 Hz using PowerLab S series
• Sensitivity: Correct for 5 μV/V/mmHg transducer standard (~350 Ω bridge)
• Accuracy: ±2 % (±0.2 mmHg) all points, after zero correction
• Input leakage current: <3 μA_rms at 240V, 50 Hz <2 μA_rms at 120V, 60 Hz
• Zeroing and offset: Automatic software-controlled fast zeroing, controlled by internal 12-bit DAC; resolution = ±0.2 mmHg (with supplied transducer)

Transducers

• Transducer type: Pre-calibrated for use with MLT0670 Disposable
• BP Transducer: no further calibration needed for normal applications
• Excitation: ~5 V_rms AC at 400 Hz ±5%
• Alternative types: Transducers up to 1 kΩ with ~ 5 μV/V/mmHg sensitivity with a 4-pin transducer connection cable require calibration.

Filters

• Low-pass filtering: Fixed 55 Hz (–3 dB) two-pole Bessel filter (limited by PowerLab setting)

Output

• Analog signal: ±2.0 V full scale

Control Port

• I²C port: Provides control and power. Interface communications rate of ~50 Kbits/s.

Physical Configuration

• Dimensions (h × w × d): 55 mm × 120 mm × 260 mm (2.2" × 4.7" × 10.2")
• Weight: 1.2 kg
• Power requirements: 2.5 W maximum
• Operating temperature range: 5 to 35 °C, 0 to 90% humidity (non-condensing)
