Looking for a Sigma 9263 replacement? OTEK’s NTM-V transforms efficiency.
Sigma Controls was founded in Perkasie, Pennsylvania, in 1985 with a focus on water-based applications for measurement and control. Picking up business as the analog age began to ride its last wave, the company cashed in on the advent of digital meters and rode that into a robust turn of the millennium. While Sigma itself has positioned itself well in the 21st century with a nod to the DPM revolution, they have left some relics behind in U.S. nuclear plants that have not aged as gracefully as their creators.
One such vestige is the Sigma 9263 analog meter. Long since fallen into the obsolescence abyss, the 9263 is long, bulky, cumbersome and prone to frustrating analog deficiencies such as display parallax and unreliable needles. Placing oneself behind the eyes of a control room operator, it’s not too difficult to imagine the frustration of being unable to quickly take a reading of the 9263 from across the control room—one has to nearly touch their nose to the instrument to read it.
