Loop Power Isolator Transmitter Technology

Ultra-efficient metering instrumentation, the New Technology Transmitter Series (NTT) have the ability to receive any signal input (AC/DC, V/A, RTD, thermal couples, etc.) and quickly retransmit that signal into the industry-standard 4-20mA loop. The meters themselves are highly programmable and are easily field configurable using OTEK’s handheld 4-20 calibrator for precise calibration and testing purposes.

Versatile and highly efficient, the NTT series boasts an impressive repertoire that includes: input/output fail alarms, AC/DC signal or signal or universal power, isolated serial I/O and flash memory, manual/serial/or signal-controlled output, over 30 input signals, and is available in 9 different models.

One of the highlight models in the series is the NTT-I, which features a single or dual isolated channel, a 4 digit display and 51 segment Auto-Tricolor bar graph, math functions of X-Y tables/polynomials, USB/Ethernet, greater than 500V isolation on all serial I/O, ±0.5% accuracy at full scale, and can be powered either by the current loop or externally. The NTT-I is also available for Mil-Spec and Class 1E/Appendix B applications and carries OTEK’s lifetime warranty. Customs are also welcome—OTEK customizes its technology to reverse engineer replacements for obsolete meters/controllers so all you have to do is Plug & Play.
