The
K800
is a precision amplifier designed to provide the researcher with
complete ease of use. Any combination of sensors may be connected to
the small Subject Unit which is connected using a 6m cable to the larger
Base Unit. All Biometrics Ltd sensors are easily connected with the
analogue output voltages standardised in the range +0 to +4 Vdc. The
LCD and 2 button switches act as the interface to configure the
individual channels for the type of sensor attached. This enables any
combination of sensors to be attached. The analogue output is via a
single cable allowing interface to a wide range of analogue data
recording systems.
The sensors are categorised
into 2 groups:-
·
Differential output bridge type sensors including:
Biometrics’
Goniometers, Torsiometers, Hand Dynamometer, Pinchmeter
·
Single
ended high level sensors including:
Biometrics’ sEMG pre
amplifier, 3 axis accelerometer
Examples of other
differential type sensors include strain gauge based devices such as
load cells and certain flow meters. A differential bridge type sensor
may be connected providing it can be powered by +5 Vdc and the output is
in the range of +/- 12 mV. Examples of other single ended high level
sensors include potentiometers. A single ended high level sensor may be
connected providing it can be powered by +5 Vdc and the output is in the
range of +/- 4 V. For all 8
analogue channels the K800 recognises automatically whether a
differential bridge type sensor or single ended high level sensor is
connected. The
K800 also has 5 digital channel inputs which are used for contact
switches and event markers. |
