New Technology Bargraph Meter   Universal Panel Bargraph Meter





Analog meters have been very useful and reliable in some undemanding applications since invented in 1893 but can not equal digital age technology where HMI (Human-Machine Interface) or MMI (Machine-Machine Interface) are indispensable. Forty years after inventing the world’s first loop-powered meter, OTEK brings you its new space-age technology to help you remain competitive by lowering your maintenance costs and eliminating the uncertainty of the analog bargraph meters. This new technology avoids the operator’s mistrust on stuck needles, which is to blame for countless accidents in nuclear, aircraft, shipboard and industrial tragedies. It allows the user to communicate directly from the process to the DCS/SCADA, whether it’s across the street or across the world!
