Type A sensor includes unlocking/locking pendulum and zero adjustment operations during the working process, and has Seismometer and force balance accelerometer with center of mass position output; B-type sensor includes no need to unlock/lock pendulum and zero adjustment during operation Seismometers and force-balanced accelerometers that do not have a center of mass position output. The design and production departments of the sensor can choose the connection according to the actual situation. mouth type. Interface and Control of Ground Motion Observation Instrument1 ScopeThis document specifies the sensor output interface, sensor input interface, timing interface, network communication interface and power supply interface of the data collector. Connector specifications and terminal definitions, input and output indicators. This document applies to the design, production, use, maintenance, introduction and quality of data collectors, sensors (seismometers, force balance accelerometers) Supervision.2 Normative referencesThe contents of the following documents constitute essential provisions of this document through normative references in the text.
