Tube impact indicator

The Shockwatch Tube impact indicator is designed to be used where space is limited.

The tube can be incorporated directly into a product’s design.

Shockwatch Tubes impact indicators are designed to be embedded into your product to monitor excessive impacts.

Shockwatch Tubes are highly visible, mechanically-activated devices that turn bright red when an impact occurs. The ShockWatch tube can be incorporated directly into a product’s design. These solutions are ideal when you need to know if product mishandling may have resulted in misalignment, loss of product calibration or warranty-related repair issues

  • Tamper-proof design prevents concealment of activation without obvious evidence of interference
  • Compliance and field tested for use in multiple manufacturing, shipping and usage environments
  • Managed and supervised to ISO quality certifications and compliance standards

Selection Guide

Shockwatch Tubes Selection Guide
Selection guides should always be used as a starting point only. The final selection will be dependent on your specific product’s characteristics and your monitoring goals.
To select the proper activation levels, determine if shock specifications exist for the product to be monitored. Most complex electro-mechanical products such as hard drives, avionics, analysis instruments, etc. have been through extensive testing to establish shock damage boundary data. If this information is available, the selection process is quite simple. Select the tube type and sensitivity to match.

FAQ's

What is a Shockwatch Tube?

A Shockwatch Tube is an Impact Detection device that will activate (turn red) when an impact level exceeds the threshold of the unit.

Where is the Shockwatch Tube mounted?

A Shockwatch Tube is embedded into the product to indicate excessive impact directly to the product. The Tube indicates whether the product was enough to absorb the damaging shock.

What can the Shockwatch Tube do for your bottom line?

The Clip can be used to:
> Promote Handling Care – Promote care and reduce damage during the manufacturing processes

> Aid in Detection of Hidden Damage – for example, Shockwatch Tubes are embedded into PCBA. The Tube products are more than damage prevention devices. They are also used for detecting possible damage or de-calibration.

> A Quality Control Tool – Many products are received and inventoried for use or distribution at a later date. Hidden damage can lead to shortages, or even to distribution and usage of damaged or faulty products. A quick check of the Shockwatch Tube can reveal the product was subjected to a potentially damaging impact and that further inspection is warranted.
