NewTek medical sensors stand up to frequent autoclave cycles

A small size, large measurement range, accuracy and resistance to environmental effects make them ideal for medical devices, especially those frequently sanitised in autoclaves that use pressurised steam or another gas to perform sterilization.

For example, the NewTek M-375 Series Miniature AC LVDTs popularly serve as components within medical devices as they are highly resistant to harsh and high-pressure environments and offer a compact 3/8” diameter size to fit tight space restrictions. With a corrosion-resistant, nickel-iron alloy housing and core, these sensors can operate in temperature extremes of -65°F to +400°F.  NewTek also provides customised LVDTs tailored to withstand repeated autoclave cycles depending on the customer’s sanitizing requirements.

In one medical device application, NewTek LVDTs serve as a component for a bone drill, delivering feedback on the depth of drilling to tenths of a millimetre so surgeons can accurately determine the depth of their drill bit during orthopaedic surgery. The sensors are hermetically sealed to withstand exposure to 220°F pressurized steam of an autoclave that sanitises the instrument.

NewTek addresses the medical market’s need for quality, economically priced standards, and customised linear position sensors. Utilizing the latest manufacturing techniques and high-tech electronics, NewTek engineers a large portfolio of AC- and DC-operated LVDTs.  All are USA-manufactured, which alleviates logistic delays in product deliveries.
