Fully-Isolated Blood Pressure Amplifiers

A totally separated blood pressure amplifier that is suitable for human use. The device is pre-set to measure pressure in millimeters of mercury (mmHg) using the included Disposable BP Transducer (stopcock) for both people and animals.

Supplied with:

Transducer Cable
Disposable BP Transducer (stopcock)

Please take note that although the transducer is packaged when it is given, ADInstruments cannot guarantee its sterility or the integrity of the packing, hence it MUST be gas sterilized before using it on human beings.

Features

To ensure subject safety, there is complete electrical isolation from power-line (mains) circuitry
Detailed examination of blood pressure in mmHg: conversion of units is handled for you
For the Disposable BP transducer, pre-calibrated
When utilizing different transducers, there is the ability to override calibration

Technical

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 ACrms for 1 minute
Amplification ranges: 50 to 250 mmHg full scale in 3 steps (combined PowerLab and BP Amp)
- 0 to 250 mmHg
- 0 to 100 mmHg
- 0 to 50 mmHg
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 μArms at 240V, 50 Hz <2 μArms 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 Vrms 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)
