METHOD TO GENERATE ELECTRIC SIGNALS IMITATING SIMULTANEOUS ACTUATION OF GROUP OF ELECTROCONTACT SENSORS Russian patent published in 2015 - IPC G01R19/00 

FIELD: measurement equipment.

SUBSTANCE: in the method to generate electric signals imitating simultaneous actuation of a group of electrocontact sensors, which consists in the fact that electric signals are generated by momentary short-circuit in measurement channels of cable line strands charged to the specified negative potential, with cable line braids, connected to a common bus (earth), signals imitating actuation of electrocontact sensors, are generated simultaneously along all channels by means of momentary short-circuit of two groups of conductors, one of which comprises connected strands of cable lines of measurement channels, charged with negative voltage, the second one - from braids of cable lines of measurement channels, connected to a common bus (earth), short-circuit is carried out with the help of an electronic switchboard with a delay relative to a signal, initiating the tested process and being the start one for time interval registration devices, the delay value is chosen as equal to the rated time of development of tested process, electric signals from outlets of generation devices are supplied to appropriate information inputs of time interval measurement devices, and along all measurement channels they determine the time interval between the start signal and signals, which imitate simultaneous actuation of electrocontact sensors.

EFFECT: inclusion of time interval measurement devices into a number of monitored devices when inspecting measurement channels functioning before measurements, reduced duration of measurement channels functioning inspection.
