Model 74 High Speed, High Shock Recorder

The Model 74 is a fully programmable, microprocessor controlled, miniaturized, high shock, solid-state, 4 analog channel, 4 digital channel recorder, designed to acquire transducer data in shock environments of up to ±50,000 G’s. The epoxy-encapsulated unit can be configured for a variety of transducer inputs to accommodate automotive crash testing, blast testing, oil and mining applications, weapons testing, or testing in other hostile field environments. The channel gain, bias, trigger levels, and speed options can be programmed into the Model 74 via a computer. Multiple sampling speeds can occur within a single test event.
