The NTM-9 digital bar graph meter from Otek Corporation is a form, fit and function replacement for analog or digital bar graph meters. The combination of modern, low-power LED technology along with a signal-loop-powered design offers low power consumption, consuming 1 percent of the power of a digital panel meter. There is no need for an external power supply, as the unit can be powered from the 4-20mA signal loop or AC/DC signal as long as the signal can supply more than 10 MW. It is hot plug installable, with isolated serial I/O and alarms. The unit is customizable for specific input, output or mathematical functions, and relays and analog output are available on powered models. 520/748-7900; www.otekcorp.com.
