    ShockLog 298 monitors and records shock, vibration and environmental conditions!

    These can be experienced by any type of structure or equipment whether in use, in transit or in storage. With the capacity to record data up to 870 events and 262,000 time slots, the device alerts you whenever damage may have occurred so you can respond promptly. Optional sensors extend the value of your Shocklog by providing more intelligence about your environmental journey. This model also has the option to factory fit an external temperature/humidity sensor into the unit (SL298-H) How the ShockLog 298 Works The new 298 has been designed to monitor shock and vibration based on acceleration or velocity measurements. 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 and vibration during transportation.  

    The new 298 has 12 user selectable ranges; Acceleration in g 1.0, 3.0, 10, 30, 100 & 200 Velocity in cm/s 1.0, 3.0, 10, 30, 100 & 200 New to the 298 are selectable hardware filters which allow users to limit the response of the unit to a select frequency range; the range covers that of all old RD298 variants from 10Hz to 250Hz. When any of the accelerometer signals or the external input exceeds the ‘wake up’ threshold the processor will be turned on and will check the sensor outputs at full speed (4098 samples per second per axis). If the output of any sensor exceeds the warning or alarm thresholds the 298 will record a detailed event and flash its status lamps accordingly. The new 298 series offers a traffic light system to inform the recipient of the potential magnitude of any given impact utilising the following sequence – Green = No Alarms, Amber = Warning and Red = Alarm. In addition, the detailed time history of the first event to set a warning, the first to set an alarm and subsequent severest events up to the installed memory capacity will be recorded, which depending upon setup, could be up to 870 Events. The 298 will adjust the recorded sample rate during the event recording (within parameters set up by the user) to make the most efficient use of memory and capture the full extent of any events.

    The 298 also supports peak recording in fixed time slots. In this mode the highest and lowest signal level present 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 also include data from other sensors.

    A feature of the new 298 ShockLog is the ability to set alarm conditions on any of the selected slot data. Most parameters have a high and low alarm setting point. These alarm status alerts will be signalled to the recipient via a different LED to the Event Alarm, with Green showing an all clear status and Red warning of a slot alarm breach. 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 10 seconds. The information from the sensors is merged into a summary record for each recording period and recorded in non-volatile memory.

    The length of the summary period can be set between 10 minutes and 24 hours and there is sufficient memory for 1024 periods. The 298 series will also include a number of features from the old RD298 EO ShockLog as a standard feature. Primarily the 298 series will have the option to set the Slot information as g-rms records providing users with the ongoing vibration levels being seen throughout a journey or during a products life. Additionally we will be including the ability to set the units into an auto-threshold mode that will slowly increment up the alarm levels as and when events occur. The primary sensors for the ShockLog™ recorder are its three built-in piezo electric accelerometers. The signals from these are amplified and filtered by several analogue circuits that must remain powered all the time. These analogue circuits are configured by the processor to have the correct gain and response for the ShockLog™ recorder setup chosen by the user. Their outputs are routed to a multi-channel Analogue to Digital converter in the microprocessor.

    The amplified and filtered signals from all three accelerometers as well as the signal from the external input on connector B is compared with a threshold level (the wake threshold). If the threshold is exceeded the processor will be woken up and will start monitoring the signal levels at the rate of 4096 samples per second. If the level of any of the signals exceeds the warning or alarm thresholds, (and various other conditions are satisfied), the ShockLog™ recorder will start recording an event. The processed analogue acceleration signals are also routed to an analogue peak hold system which stores the largest signal seen on each accelerometer. This peak hold system is measured and cleared by the processor every 5 seconds and the data from it is the key input for the Time Slot view of the acceleration data. The ShockLog™ recorder records acceleration and other environmental data in three ways simultaneously - Summaries, Events and Time Slots. A fixed amount of memory is allocated to each recording method. The information from the sensors is merged into a record for each recording period and recorded in non-volatile memory.

    The length of the recording period can be set between 10 minutes and 24 hours and there is sufficient memory for 512 periods. The external inputs are intended for use with low bandwidth devices such as pressure or humidity sensors and, in addition, the first external input can be used to trigger the ShockLog. The ShockLog also supports peak recording in fixed time slots. In this mode the highest and lowest signal level present on each input is recorded for each time slot. The time slot length may be set between 10 seconds and one hour and as many as 262,144 slots may be recorded. Communications The new 298 ShockLog has several mediums of communication. The primary method is via USB, the new ShockLog PC software automatically finds an attached unit there is no need to identify which USB port is used. The new 298 ShockLog has been designed with a IP67 water tight USB connector when using the appropriate mating part; where conditions do not dictate a fixed water tight link a standard cable can be used. The supplied water tight cap should be refitted after communications are complete. Should the cap be left off the unit remains water tight but the exposed connections may become tarnished which may lead to poor communications.

    For a quick and simple way of starting or stopping a unit in the field an I-Button interface has been added. This also allows for the download of a ‘one page report’ giving a condensed view of the journey data gathered. There is an RS232 Serial Port for legacy devices and third party device interfacing and a new 1 wire IMC bus for newer peripherals.

    There are two option communication interfaces that can be added, these must be specified at time of order.

    • This allows for interfacing to automotive and other CAN derivative networks. The code associated with this interface is likely to be customer specific. 2,4GHz radio link
    • The ZigBee Radio Communication module gives real-time data transfer for fixed applications & auto download upon arrival for mobile unit security.

    The new 298 ShockLog stores all data and status information in high performance FLASH memory. This memory requires no power to retain data. The instrument is configured by connecting it to a PC, and running the data analysis / set up software. During the configuration process the operator can set the levels for warnings and alarms, determine the sensor types to be used and enable passwords, although not mandatory, for subsequent access to data. Before the software will communicate with the 298 the user must supply any passwords, which may have been enabled to restrict access to data, resetting, or other functions. An area of the flash memory is reserved for the security log – this records the timing of such actions as re-setting the clock or clearing out data and cannot be modified by the operator. It is intended that the security log last the operating life of the instrument and will only be cleared when the ShockLog is re-calibrated. Packaging and Environment The 298 has been designed to function reliably in difficult environments.

    The electronic components are assembled using surface mount technology and the latest automatic assembly equipment. The complete electronic package is coated with acrylic resin and enclosed in the metal case. The securing bolts pass right through the body of the instrument to guarantee a reliable mechanical installation. This construction technique, in combination with the absence of cables for power or sensors results in a very high immunity to electrical interference and very low levels of RF emission. The 298 may safely be used in close proximity to sensitive instruments or in difficult electrical environments. The 298 has been designed to meet IP67 (including connectors) and is capable of operating at temperatures between –40 and + 85°C.
