Medical Precision

With the increasing importance of integrated advanced technology in the medical device sector, WCL has transferred expertise and engineering precision from defence market offerings, to become a premier supplier to manufacturers of systems, such as ECG, ultrasonic monitors and other diagnostic equipment.

“Our aim was to capitalise on WCL’s experience in precision and reliability factors that are crucial for military electronics, hence producing technologies and components that have led to better and more advanced products in the medical device field” comments John Graham, Marketing & Sales Director - Welwyn-TT.

Design engineers working on high voltage power supplies in medical X ray equipments rely upon specialised application resistors to achieve accuracy in measurement and control of the accelerating potential. WCL have several solutions that supply working voltages of up to 100Kv, allowing cost effective levels of reliability, with custom thick film planar and the well-established T series technology.

For defibrillation pulses, WCL can offer both low (470R – 2K2) and high (68R – 100K) resistance products. Firstly, the CCR1 series, replaces traditional carbon composition resistors, which are almost unavailable across world markets. Secondly, the series of power surface mount resistors (PWC Series) offer 50% more power than a conventional 2512 chip.

Amplification circuits rely on resistors with higher than normal precision or value to achieve sensitive detection of small signals. WCL can provide the engineer with five families of resistor to cater for MRI scanner, ECG monitor and electron microscopy applications – these are the RC, HR, HVC, PCR and PCF series.

WCL also manufactures a wide range of current sense resistors to provide enhanced motor control performance in blood transfusion equipment and laboratory pumps.

Part of TT Electronics, Welwyn offers its customers a total technology solution through its global multi-site manufacturing base. By offering this one stop design and manufacturing source, Welwyn can continue to offer customers a consistently high level of supplier reliability to help customers maintain a strong presence in its product arena.
