International Instruments began 1947 with the purpose of developing a series of analog meters that realized the full of a flat, stackable, and compact meter. As the Nuclear Power Industry grew exponentially after World War II, so too did the escalating need for improved nuclear instrumentation. Initially developed for the U.S.-based Atomic Energy Commission, II’s 1146 model boasted accuracies of DC: 1.5 or 2 % and AC: 2.5 or 3%. Obviously the times have changed—the red carpet of technological progress has made meters more accurate, more reliable, and frankly, an accuracy range of 1.5 to 3% is just flat-out dangerous when talking about nuclear energy.
Compare that with Otek’s NTM-V, whose accuracy is firmly 0.5%.—nearly 3x that of II’s analog! This of course, is in addition to the fact that by utilizing digital technology and Otek’s luminous LED readout display, there is no room for operator subjectivity—the number displayed is precisely the number displayed, no craning of the neck or viewing of different angles.
To that end Otek offers the NTM-V as a 100% Form, Fit, and Function replacement for the International Instrument 1146 model, for Class 1E safety related and nuclear qualified, as well as Mil-Spec 461, 167-1, 810F, 901C, and IEEE-344 respectively. Following the policy of all models in our New Technology Line, the NTM-V comes with a cyber security compliant classification.
The NTM-V housing is an industry standard 5.7 x 2.84” available in metal only and comes equipped with a 51 segment programmable tricolor bar graph and four digit LED display. Highlighted features include self-diagnostics in conjunction with our patented input signal fail alarm with runtime stamp, serial I/O with USB and RS485 options, over thirty isolated input signals, 4-20mA/30V Output on externally powered units, configurable bar direction (up, down, center/zero) with intensity control, and requires only 10mW@5VDC.
The NTM-V, like all our products, carries our guaranteed lifetime warranty, and is fully customizable to nearly any application.
