NTM-X | Explosion-Proof Meter

The NTM-X is a replacement for any explosion-proof meter. Industry-standard 4.3″ W x 3.9” H explosion-proof metal housing.

This single-channel Bar-Digital meter/controller 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.

New Technology Meters | Series Information

Analog meters have been useful and reliable in some undemanding applications since invented in 1893. Still, they 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 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 the world!

All New Technology Meters share the same innovative electronic circuit design. The difference between the models is their mechanical features (see Block Diagram and mechanical drawings). Some are displays only, some are single or multi-channel, some can have relays, DACs, ethernet, and flash memory, and some require an external power source. But all products contain the New Technology, which consumes less than 1% of the power of comparable digitals (20-100mW for loop/signal powered versions) and approaches the power consumption of analog meters.
