Hays Cleveland D03600 & It’s Future

Imagine you’re working in an I&C room with numerous meters and display panels strewn over every conceivable wall, and you need to perform daily checks. Does this five gauge meter look “easily readable from a distance” and do you trust that its “full size is used to assure big-gauge accuracy and sensitivity” as its datasheet claims? Common sense is all that should be required here to answer no.

This clunky and dubious meter is the Hays Cleveland D03600 – a stalwart at many Nuclear Power Plants, particularly in the Diablo Canyon facility near San Luis Obispo in California. Like all analog meters, it does not lend itself to visibility across a control room or ensure complete accuracy due to the negative common denominators associated with most analogs: inaccuracy, unreliability (stuck needles), and subjectivity. This is one of the many faces of the 21st century’s inexorable obsolescence crisis, and the question remains the same–why plow ahead with outdated and unreliable instruments when new technology exists to address the problem?

Instead of burying your head in the sand, take a look at OTEK’s NTM-B model, which we offer as a 100% Form, Fit, and Function replacement for the Hays Cleveland D03600 for Class 1E safety-related and nuclear-qualified applications, as well as Mil-Specs 461, 167-1, 810F, 901C, and IEEE-344. As with all models in our New Technology Series, the NTM-B is Cyber Security Compliant.

The NTM-B is housing is an industry-standard 3.8 x 1.9” (verticle1/8 DIN) and is available in plastic or metal, as well as carrying a 51 segment programmable tricolor bargraph and four-digit LED display. Additional features include our patented input fail alarm with runtime stamp, self-diagnostics, USB/RS485, over 30 isolated input signals, intensity control, 4-20mA/30V output, configurable bar direction, and a multitude of power input options on externally-powered units. Like all our products, the NTM-B also comes equipped with our lifetime warranty and is fully customizable to consumer needs.
