Designing Instruments to Fit Your Needs

Reverse Engineering

OTEK specializes in reverse engineering obsolete analog and digital instrumentation. Our flexible technology allows us to retrofit virtually any type of meter into a Form, Fit, and Function replacement designed to fit right into the preexisting panel cutout, wiring, terminals, etc. This is part of our “Plug & Play” promise to our customers—OTEK does all the hard work, so all you have to do is Plug & Play!

Reverse engineering allows for obsolete meter replacement.
Examples of OTEK’s Reverse Engineering Applications:

    1. A nuclear client needed to replace their obsolete Dixon SH101 and the Dixon 202p, as well as several of the industry-wide Bailey’s RY analog meters. It was essential to the client’s I&C room’s efficiency that these analogs be replaced 1:1 as they fail. After receiving samples of all three analogs, OTEK was able to reverse engineering Form, Fit, and Function our NTM-6 model to replace the analog meters using the same panel cut-outs, wiring, and with only minimal new training for the operators.

2. In 2018, another nuclear plant in the New England region was also the recipient of our NTM-6 to replace the Bailey RY series. OTEK custom-designed a dual-channel NTM-6 with a 4-20mA input to fit inside the existing RY housing after evaluating a sample provided by the customer. Our engineering department also designed a customized inner edge connector to fit with the existing connections of the RY meter.

3. In 2016 OTEK developed our HI-Q118 and its subsequent replacement, the NTM-8, for a nuclear client right here in Arizona. The client was looking to replace a large cache of the popular Foxboro 257 analog meters. The HI-Q118 model met these specifications Form, Fit, and Function with isolated USB capabilities for the serial i/o and 10-32 VDC power. Also, utilizing an 8″ deep housing, these units for sold commercial grade and were then replaced by the NTM-8 as newer, more innovative technology became available.
