METHOD FOR RECOGNISING A SENSOR AT A MEASUREMENT AMPLIFIER AND FOR AUTOMATICALLY ADAPTING A MEASUREMENT AMPLIFIER TO A SENSOR

摘要

the invention relates to a method for detecting a sensor on an instrumentation amplifier and a method for synchronization of a sensor with an instrumentation amplifier. the sensor (1) by means of a plug 5 with an instrumentation amplifier (4) doors. the instrumentation amplifier (4) comprises at least a pair of contacts (11) with a first contact (12) and a second contact (13).the plug (5) comprises at least one a pair of contacts (7) with a first contact (8), and a first contact (8) coupled the second contact (9), with the contacts of the messverstu00e4rkers (4) and the plug (5) with each other kontaktierbar.to detect whether the sensor (1) to the instrumentation amplifier (4) is connected, the instrumentation amplifier (4), an electric potential at a contact of the kontaktpaares and measures the electrical potential of the second contact of the kontaktpaares, with the instrumentation amplifier (4), the electric pot ential the first contact with the electric potential of the second contact are compared.the instrumentation amplifier (4) is due to the same potential to the contacts, a sensor (1) is connected, the instrumentation amplifier (4) data from a memory (2) of the sensor (1) are read out and the messverstu00e4rkers (4) is determined on the basis of the selected data is adjusted.
