Data Logging

Remote Vibration Data Collection

A new service is available for remote data logging of vibration and shock data collection. Typical applications include recording of shock forces experienced during transit of sensitive (or valuable equipment such as artwork or electronics) during shipment to identify exact time of excessive shock during collection, transit, delivery or even post delivery handling. These self contained data loggers are programmed to record in real time at required intervals and the results are then downloaded and analysed by AVMR technicians for reporting. Analysis of building and plant applications are also conducted in a similar way.

In all applications it is necessary to firmly attach the unit via the two 6mm x 61.25mm pitch mounting holes. In certain cases this can be via an intermediate mounting plate.

The graph below clearly illustrates periods of occupancy of a building during a week-long period with early evening activity also. Any period can also be displayed for greater detail as seen in the second graph below.

Based on a pre-programmed start time, it is easy to identify the actual time of an event. In the above graph the first interval started at 00:00hrs. i.e. the 499^th interval was at ((5 x 499)/60) = 41.58 hours later – almost 6pm on the second day.

Features include:

Reading range 0 to 5g
16,000 reading capacity (programmable in various intervals 1 sec to 10 days
Robust waterproof cases (IP68)
Pre-programmable (at AVMR) – return for data extraction and reporting
Delayed and trigger start options
User-replaceable battery for prolonged logging periods (>6 months)
Self contained fully portable unit
Memory type Non Volatile (if battery runs down, data is preserved)
Delayed Start Relative / Absolute (up to 45 days)
Stop Options:
- When full
- After n readings
- Never (overwrite oldest data)
- Reading Type - Maximum during time interval
- Logging Interval 1 sec to 10 days
- Reading Range 0 to 5g (49m/s2)
- Sensor Type Piezo Electric
- Accuracy* ±5% Reading +0.02g (*The accuracy figure stated is based on shocks approximated by a half sine wave of length 2ms to 20ms. The logger is less sensitive to shocks either slower or faster than this range.)

Linearity ±1% Full Scale Deflection
Resolution 0.02g (0.2m/s2)
Battery Type SAFT LS14250 or LST14250;Tekcell SBAA02P
- Replacement Interval Annually
- Before replacing the battery the data logger must be stopped.
- Data stored on the logger will be retained after a battery is replaced.
- If used at low temperatures the data logger should be allowed to warm to room temperature before it is opened to avoid condensation forming inside the unit.
The waterproof IP68 rating is valid only when the unit’s connector cap is fitted and is valid to a depth of 15m (50ft).
The TGP-0605 records the magnitude of acceleration experienced by the unit along the axis running through the logger’s lid to its base. To avoid reading errors the logger must be securely fitted to a flat surface using the unit’s two mounting flanges.
This data logger contains sensitive electronics which may be influenced by strong electromagnetic signals. Keep it clear of any sources of electrical interference, especially mobile phones, whilst logging.
