The Many Uses of Otek Meters

On this day in history, Frank (Julian) Sprague died at the age of 77 in 1934. Sprague was an American engineer, inventor and a pioneer in electric railway transportation. He worked with Thomas Edison at Menlo Park and formed the Sprague Electric Railway and Motor Company in 1884 and became known as “the father of electric railway traction.” His company installed the first U.S. electric trolley system in Richmond, Virginia in 1887.

Did you know that Otek’s instruments are used in electric railway systems throughout the world? Otek is in the business of measurement, and our accurate and bright digital meters are perfect for the infrastructure, equipment and power systems needed to run any efficient rail system.

Take a look at our model NTM-3, which is a perfect fit for any modern rail cab or system. This switchboard meter is available with up to three channels (i.e. to monitor speed, distance, rate, etc.,) and offers isolated serial communications to relay information back to the central computer. This unit also includes built-in math functions, self-diagnostics and can be configured for over 30 isolated input signals. Thank you Mr. Sprague for your contribution to the rail industry and for proving Otek with more variables to measure!

Commercial Grade Dedication Training

As part of our continued dedication towards our Nuclear Quality Assurance Program (as required by 10CFR50, Appendix B), we are pleased to announce that Otek Corporation’s Chief Engineer, Noel Smith, will soon be attending a 3-day Commercial Grade Dedication class.

The three-day course, which will be held at the Nuclear Training Institute in Norcross, Georgia, is designed to provide engineers with a better understanding of how Commercial Grade Dedication is applied in order to meet NQA-1 requirements. During the course, Noel will further his knowledge of the Commercial Grade Dedication process and will receive supplemental training on such important topics as how to identify the safety function and critical characteristics of a design and how to establish production traceability.

Although Noel has received extensive training on the Verification and Validation of safety-related software and firmware, this focused class will ensure additional compliance with 10CFR regulations. Noel is a 2004 graduate of NAU and holds a Bachelor’s Degree in Electrical Engineering, with a secondary emphasis in Computer Science.


Otek Corporation will be attending the ANS Winter Meeting & Nuclear Technology Expo, which will be held from October 29th through October 31st at the Marriott Wardman Park Hotel in Washington, D.C.

We would like to invite all attendees and all members of the American Nuclear Society to visit us at booth # 101, which is located just to the right of the main entrance.

As part of our exhibit, we will be unveiling our new SSAM-N. The SSAM is a Solid State Analog Meter that replaces form, fit & function an ANSI 4” switchboard analog meter. This instrument is unique in that it has no microproecessors, making it safe from hackers and exempt from cyber security regulations. SSAM is powered by the signal it measures, just like an analog meter, but without the stuck needle and inaccuracy and the sensitivity to shock, vibration, EMI/RFI and without the lack of HMI of the analogs.

Some features of this innovative technology include:

100% Signal or External Powered
Current Loop (4-20 & 10-50mA) or AC/DC V, A, W & Hz Input Signals
Tricolor 101 LED Bargraph & 4 ½ Digits
No Microprocessors (Cyber Security Restrictions Exempt)
Input Signal Failure Alarm (No stuck Needle)
​Come visit us at booth #101 and meet SSAM!

Nuclear Audit to be held at OTEK Corp

We are pleased to welcome representatives from APS Palo Verde and PSEG Hope Creek nuclear power plants, who will be visiting OTEK World HQ in Tucson, AZ the week of June 26, 2017. This will be the first audit of OTEK’s new Nuclear Quality Assurance program as required by 10CFR50 Appendix B and 10CFR21.

This is an important first step for OTEK to be placed on the Approved Suppliers List (ASL) for these two plants. Inclusion on the ASL permits OTEK to be a direct supplier of safety-related instruments, analog meter replacements, digital panel meters, digital bargraph meters and controllers for these plants.

Any utilities who would like to participate in this audit are welcome to contact Dale Leech ( for more information.

Early Returns from the ANS Winter Conference

Nuclear Industry on Life Support… How Can OTEK Help?

Dr. Fest has returned from the sun and sand of Orlando, Florida, where he received dour news from industry leaders around the world at the ANS Winter Conference. The Nuclear Industry, it seems, can no longer bury its head in the proverbial sand. A cloud encroaching from the not too distant horizon with promises of expensive and time-consuming storms had everyone in central Florida’s ears ringing with alarm. The writing appears to indeed be on the wall–the Nuclear Industry is facing an obsolescence crisis short on options and even shorter on time.

With 80% of power plants worldwide 30 years and older, AND using mostly analog meter technology from the 1st half of the 20th century, the clock is ticking on obsolescence. Couple this with governmental oversight in the form of crippling NEI 08-09 regulations, and you have a maelstrom of inefficiency, expenditure, and evasive R.O.I. The solutions? Well, they are not without their problems. You can replace your old analog meters with modernized digital instruments such as SCADA/DCS or Flat Screen technology. Still, then you’re looking at not only an investment upwards of $100 million and five-plus years but also potentially $20 million in Cybersecurity Compliance! Does investing nearly $150 million (calculated loss of income from 3-5 year upgrade shutdown included) in a 30-40-year-old power plant seem wise?

As he emphatically demonstrated in Orlando, Dr. Fest and his small company from the desert have a better solution that just might keep that cloud at bay a little longer. Dr. Fest unveiled OTEK’s brand new Solid State Analog Meter (SSAM), which replaces analog meters 100% Form, Fit, and Function, AND is entirely Cybersecurity Exempt! What? How can an instrument endowed with OTEK’s patented New Technology avoid Cybersecurity regulations? Dr. Fest’s answer was to take the award-winning technology of his NTM series and, using CMOS logic, insert it into a fully hardware-driven instrument void of any critical digital assets. Without these CDA’s such as microprocessors, there is nothing in the SSAM that could be hacked or compromised by an outside source, thus bypassing the Cybersecurity problem and subsequent regulatory expenses!

During his time in Orlando, Dr. Fest was able to raise many eyebrows with the efficiency and practicality of the SSAM. For companies uninterested in the high cost of Cybersecurity compliance, the SSAM offers a way to avoid losing millions while at the same time gaining an advantage in the latest digital meter technology. Dr. Fest returned home to his small company with hope for the industry as that long black obsolescent cloud draws near. Remember, it was David who defeated Goliath!
