摘要:
A system for detecting tampering in a signal conditioner of electronics that determines a parameter from signals received from one or more sensors is provided. The system includes a host system that receives the parameter signals from the signal conditioner indicating properties of a material and supplies power to the signal conditioner. The signal conditioner is remote from and coupled to said host system. The signal conditioner generates the parameter signals. The host system is configured to periodically transmit a request for said authentication information to said signal conditioner, receive said authentication information from said signal conditioner in response to said request, compare said authentication information with initial authentication information, and detect said tampering condition in said signal conditioner if said authentication information is not equal to said initial authentication information.
