The NTM-6 housing is an industry standard 7 x 1.4” in metal. This unit houses up to 2 channel and is available in loop (4-20mA), A.C. signal or external power to replace fit, form and function any analog or digital panel meter. Our Powerless (loop/signal) versions only consume <60mW, comparable to an analog meter! The external power series features over 30 signal conditioners. The unit is equipped with a 51 segment automatic and programmable tricolor bargraph and four digit LED display (18.104.22.168 and -22.214.171.124). Standard factory set color changes are: red: <10 and >90%, yellow: <20 and >80%, green: >20 and <80% of full scale (you can change it with simple commands). The NTM-6 features automatic signal fail detect (open or short) and serial transmission with run time stamp and unit ID. Serial communication options include USB and RS485, externally powered units include the additional options of Ethernet and flash memory (µSD). Our patented (and pending) hardware and firmware gives you the highest reliability at the lowest cost. Our flexible firmware allows the NTM-6 to operate efficiently with improved response time and offers several math functions such as X-Y tables, polynomials and log-anti-log functions. Additional features of the external powered NTM-6 include isolated retransmission (4-20mA or 30V), universal power inputs (5-32VDC or 90-265VAC) and control output options of O.C.T. (4/channel) or relays (4/channel). We have combined over 40 years of experience with the latest ASIC uC and ultra-efficient multicolor LED technology to bring you into the 21st century.
