CTC Line Unconditional Lifetime Warranty in Action

CTC is proud to offer the industry's best warranty on all CTC Line products (indicated by the red CTC logo), including accelerometers, loop power vibration sensors, cables, connectors, mounting hardware, and more.

If any CTC Line product should ever fail for any reason, at any time, CTC will repair or replace the product free of charge.  

We not only offer you the highest-quality products on the market, but we also offer you unmatched service and peace of mind for the lifetime of your CTC product. Here a just a few reasons we've offered hassle-free, free-of-charge repair or replacement to our valued customers:


Please note: should you wish to return your product for a repair or replacement under warranty, the product must be identifiable. Therefore, we require products to be returned with their distinct, original labeling OR complete set of components. This means that a legible cable label or engraving must be visible in order for CTC to validate and repair or replace the returned product. If the original labeling has been burned off, damaged, or is no longer legible, CTC requires that all components of the damaged product be returned along with a valid proof of purchase. Products that do not meet these qualifications for warranty will be returned in their current condition.

Seeing is believing! View examples of products that our customers have returned for convenient, complimentary repair or replacement:

Long-time CTC customer, Jim Lancaster, shares how CTC stands behind its promise to provide customers with the best support in the industry:

“I have been using CTC accelerometers and cables on underwater pump applications for many years very successfully. One of my customers, a municipal water utility, was planning to remove and repair several of their pumps for a routine upgrade. Their pumps are substantially larger than average and they hoped to not remove these pumps for a minimum of 10 years, due to the size and expense of installation.

I was able to persuade them that obtaining vibration measurements directly from the pump would be beneficial. Within a few days of installation, both sensors failed. CTC not only replaced the failed sensors (without a product return, as they were inaccessible) but in this circumstance, they doubled the volume as we felt bad about their unusual experience and this would allow them to place sensors on the next two pumps.

About a month after the second pump was installed these sensors also failed. CTC Owner, Todd Cook was notified of the failures. Immediately, testing was done for water incursion and it was discovered that recently an automated welding machine was updated at the factory, which regrettably was not set up properly by the manufacturer after purchase, allowing water incursion into the sensor.

Todd requested that the sensors and cables be returned, so he could replace them. Unfortunately, this was not an average installation and it was cost-prohibitive to remove the pumps from the river. Todd asked if there was any other way to access the sensors. The customer somewhat jokingly mentioned that they occasionally use a dive team. Todd requested they get a quote and commissioned the dive team to replace all the sensors.

Previously, leak testing was not performed on every sensor that was produced. Now, as a result, 100% of the sensors are leak tested. The replaced sensors currently remain in service many years later.
