Featuring a bright LED display, the new DMR20 series is suitable for mounting in an industry-standard “oiltight” 30 and 30.5 mm / 1.2 inch round panel cutout. The DMR20-1-FM-R-C frequency monitor is a self-powered, 2-wire meter that does not require any additional external power sources. Equipped with a quartz crystal controlled microcontroller-based timing circuitry, this monitor is a companion product to Murata’s AC voltmeter, model number DMR20-1-ACV-R-C.
The meter has a display resolution of one hundredth of a Hertz (0.01Hz), making it an attractive replacement for outdated analog frequency-meters. The unit features a rugged housing with seamless construction on all sides, providing protection to IP67 / NEMA 6 specifications for dust, dirt and moisture. It can operate from -25 to + 60ºC.
