1). Double color LED display, with correct intuitionstic and stable indication. Ahead closewise rotation: Yellow LED is on; Astern counterclosewise rotation. Red LED is on; Installation: Both yellow & red LED on;
2). When rotation speed of vessel stern shaft equal or less than 20rpm/min, tachometer indicate stop rotating; technical symbol: -0 ahead, astern LED is on at the same time;
Equipped function of auto-lightness adjustment, in order to reduce contrast between highlight and darkness;
3). Use two-way passive transduer, non-contact magnetic induction measure, with the characteristic of high sensibility, far sensing range, high temperature & pressure & humidity endurant, not afraid of oil pullution & mist, alnico induct to measure, no need heavy measuring gear and easy installation.
Digital intelligent meter are electric unit measuring instrument with function of programmable measurement,display and digital communication, etc. Utilize AC/DC sampling technology, be able to measure current, voltage, power, frequency in power transmission & distribution system,
widely used in power transforming, distribution automation, intelligent building and power monitoring,
site-inspection & remote monitoring also available.
