EQUIPMENT SYSTEM FOR CONTINUOUS DETECTION AND MEASUREMENT OF MOTOR ACTIVITY OF BIVALVE MOLLUSCS Russian patent published in 2012 - IPC G01N33/18 

FIELD: physics.

SUBSTANCE: equipment system includes measuring devices connected to a computer. In the system, consisting of one or more sensors, an amplifier, an analogue-to-digital converter (ADC) and a computer, each sensor is a tensoresistor sensor mounted on a horizontal base inside a protective housing and having the end of a flexible elastic sensor plate protruding from the housing, said plate being meant for connection with the top valve of the tested mollusc. The output of each sensor is connected to the input of the amplifier consisting of a zero balancing device, an analogue signal amplifier and a signal shift device connected in series. Each sensor is connected to the bridge circuit of the zero balancing device. The output of the amplifier is connected to the input of a 10 bit ADC whose output is connected to the input of an interfacing device which transmits a digital signal to the input of the computer having special software.

EFFECT: high accuracy and reliability of detection as well as simple design.
