ShockLog 248 Impact Recorder Technical Data The ShockLog 248 impact recorder is the intermediate FEATURES model in the SpotSee series of impact recorders. The ShockLog 248 combines advanced tri-axial pieza electric Records impact events max peaks X, Y, and Z accelerometer technology with sophisticated low power and internal temperature electronics to oeff r an advanced shock recorder with outstanding baett ry life. Available in 10G, 30G, and 100G Field-proven tri-axial piezoelectric impact scale range, the ShockLog 248 monitors impact accelerometer technology and internal temperature, provides peak value (mti e slot) and summary period journey prolfi e data. The ShockLog User-definable wake up and alarm levels 248 will record the detailed impact curve of up to 15 events (the first and 14 most severe). Up to 128 event LED lights for visual notification of alarms notifications are maintained in the event summary log.

It has several unique features, which make it especially suitable for applications where the cost of exposure to out-of-specification environmental influences is very high. The instrument is equally suitable for protecting high-value fixed or mobile installations and investigating shock during transportation. The ShockLog 248 has a choice of 3 factory-defined ranges: Acceleration in G: 10G/40Hz, 30G/90Hz or 100G/250Hz If any of the accelerometer signals exceeds the wake-up threshold, the processor will turn on and will check the sensor outputs at 2048 samples per second per axis. If the output of any sensor exceeds the alarm threshold, the ShockLog 248 will flash its status LED accordingly. In addition, the detailed time history of the first event to set an alarm and subsequent severe events up to the installed memory capacity will be recorded. The ShockLog 248 has the capability of recording the 1st followed by the 14 most severe events as detailed curves and continually checks the impacts against the previous severe events. If that impact is greater in magnitude than the previous 14, it replaces the detailed curve and the remaining impacts will show up as Max X, Y and Z values with time stamps at the event time. The total number of event notifications stored is 128. The ShockLog 248 supports peak recording in fixed time slots. In this mode, the highest and lowest signal level measured on each input is recorded for each time slot. The time slot length may be set between 10 seconds and 1 hour, and as many as 51840 slots (peak x, y, z and temperature) may be recorded. The slots may also include data from optional sensors such as temperature and humidity. A feature of the ShockLog 248 is the ability to set alarm conditions on any of the selected slot data. Most parameters have a high and low alarm setting point. In additional to events and time slots, the device checks the output of the sensors (the three built-in accelerometers, the built-in temperature sensor and any external sensors) once every 5 seconds. The information from the sensors is merged into a summary record for each recording period and recorded in nonvolatile memory. The length of the summary period can be set between 10 minutes and 24 hours and there is sufficient memory for 512 periods. www.spotsee.io 2
