ShockWatch Impact & Environmental Recorders help monitor and record impact and shock vibration to your equipment, structures, and storage environments — ensuring protection from costly damage. Additionally, they provide an ongoing record of the environmental conditions of the product, equipment, or structure being monitored. ShockWatch Impact & Environmental Recorders monitor critical goods and equipment that need special care and handling in transport, storage, and use. Shock, vibrations, and unacceptable environmental conditions can cause costly damage. Identifying responsibility for these unacceptable conditions is the first step in preventing damage and downtime.

ShockWatch Impact & Environmental Recorders provide ongoing monitoring of the intensity and duration of shock and vibration to large stationary or moving equipment, structures, and products. Tri-axial piezo-electric accelerometer technology is used to record impact direction, amplitude, and duration. Optional sensors also record changes in temperature, humidity, and atmospheric pressure.
Micro ShockLog - RD317
This device records the date and time of up to 128 events, in addition to peak values of impacts at user-specified intervals. Optional accessories include a humidity sensor.

Innovative Software for Reliable Data and Analysis The ShockLog and Micro ShockLog are offered with a comprehensive Windows-based software program that allows you to program your own wake-up, warning, alarm levels, and frequency of data collection. When a pre-programmed impact level is exceeded, data will be stored for future analysis. With the software, you can also configure the devices directly or via iButtons to extract data and generate reports and charts. |
Micro ShockLog Technical Information
How the Micro ShockLog Works
The ShockWatch Micro ShockLog combines advanced tri-axial piezo electric accelerometer technology with state of the art electronics and field proven software. The end result is a remarkably affordable advanced shock and vibration monitoring instrument.
The Micro ShockLog can record impact and temperature events over time frames up to 17 months or more. In addition, the Micro ShockLog is the first full function shock recorder to allow setup and data extraction in the field without a PC or other hand held computer.
During operation, low power analog circuits continuously monitor the signals from the three built-in accelerometers. The peak value of acceleration in each timeslot period is recorded in the timeslot memory.
The timeslot period can be set to as little as 10 seconds or as long as one hour. The detailed event recording system will be triggered if the level of acceleration from any sensor exceeds a preset threshold. This function will record the event at a rate of up to 1,024 measurements per second on each accelerometer. Sampling rates and event duration can be set by the user. Since only a finite amount of memory is available, the detailed recordings for the first and the most significant events are recorded. In addition the maximum values for X, Y, Z and the modulus for the most recent 128 events are recorded along with the event time stamp.
Security
The Micro ShockLog stores all data and status information in high performance sector erase FLASH memory. This memory requires no power to retain data and offers special hardware protection against accidental erasure. Before the software will communicate with the Micro ShockLog the user must supply any user passwords which may have been set to restrict access to data, resetting, calibration or other functions. If the iButton interface is used passwords may still be configured if required. A special section of the flash memory is reserved for the security log -this records the timing of such actions as removal of the battery, resetting the clock or clearing out data and can not be easily modified by the operator. It is intended that the security log last the operating life of the instrument and should only be cleared when the ShockLog is recalibrated by ShockWatch.
Packaging and Environment
The Micro ShockLog has been designed to function reliably in difficult environments. The electronic components use surface mount technology. The complete electronic and transducer package is coated with acrylic resin and enclosed in a metal case. The construction of the Micro ShockLog along with the absence of cables for power or sensors results in a very high immunity to electrical interference as well as very low levels of RF emission. The unit may safely be used in close proximity to sensitive instruments or in complex electrical environments. The Micro ShockLog has been designed to meet IP67 (including connector with cap fitted) and is capable of operating at temperatures between - 40°F/-40°C to +185°F/+85°C.
