"This letter is a Part 21 notification to the US Nuclear Regulatory Commission of a potential component defect.

"The ITT Conoflow models GT25CA 1826 and GT25CD1826 current to pressure (l/P) transducers produce a calibrated 3.0 to 15.0 psi output pressure from a 4.0 to 20.0 mA DC (input) signal.

"On May 5, 2017 a non-safety related GT25CA 1826 was received for evaluation. This transducer would not respond to the 4 to 20 mA operating signal. The failure was caused by a defective solder joint at a coil lead terminal on the printed circuit board. The circuit board was replaced and the unit worked correctly.

\,

"An immediate inspection of all stock revealed additional parts with defective solder joints. Based on our [Enidine]

investigation, circuit boards with defective solder joints are limited to two lots, received on April 29, 2016 and May 27, 2016. Preventive measures have been implemented to prevent recurrence.

"We [Enidine] have produced and shipped the following safety related products that have used parts from these two lots of circuit boards:
