Adtech are specialists in producing fluoroplastic probe covers for stainless-steel temperature-detection and level-detection sensors, both for medical procedures and industrial applications too.
Why choose to cover your probes in fluoroplastic?
The answer is that fluoroplastics such as PTFE, FEP, & PFA are some of the most inert materials known to man, and they also have a very high temperature resistance for polymeric material too, making them non-stick. This makes them particularly useful for protecting sensors in applications where highly corrosive or solvent conditions exist.
Fluoroplastics are relatively difficult materials to process, but by using a combination of moulding, shrinking, welding and spraying techniques, we can create fluoroplastic probe covers of any length and diameter, without damaging delicate sensor elements inside.
How do we do it?
We use a variety of technologies to encapsulate measurement elements, including FEP shrinkable tubing, moulding, spray coating, and fluoroplastic welding. This enables us to produce probe covers from 0.5mm to 40mm diameter at any length, and we also offer a complete assembly service to insert sensors into the covers, sourcing all components where necessary.
Getting your probe covers from Adtech is generally also much more cost effective than other methods. This is because we have the equipment to produce and store FEP shrink-fit covers of varying thickness and tip profiles in-house. So whatever number of probe covers you need, we can easily produce these for you ourselves, so that you can mitigate needing to over-buy in bulk.
Probe Cover Production – A Case Study
For this project, our medical industry client wanted to create a small diameter sensor probe suitable for a new microwave treatment for patients. The probe covers needed to feature a hemispherical-domed tip with a consistent wall thickness at the sealed tip, as this was the area designed to control each dose of microwave treatment. They also needed to form a secure autoclave so that nothing external could permeate the treatment process from the outside, and be flexible enough for multiple usage, as well as potentially suitable for use within the body (bio-compatible).
