Yokogawa blue star ltd supplies an upgraded version of low-cost mr series microprocessor based recorders. These microprocessor based recorders support universal inputs [all types of thermocouples, rtds, 4-20 ma, dc volts and digital input]. Various models of microprocessor based recorders for 1, 2, 3, 4 pen and 6, 12, 18, and 24 point with 100 mm and 180 mm chart widths are available. These microprocessor based recorders contain a powerful set of recording and printing characteristics like analogue recording, digital periodic printout, alarm printout, message printout, chart speed change printout, manual printout and recording start printout. Some special features of the microprocessor based recorders include: zone recording that allows users to set a distinct analogue recording and pen offset compensation which omits time/phase skew between the pen traces in 2, 3, and 4 pen recorders. The microprocessor based recorders come with large, bright dot matrix vfd display, which makes measured values clearly noticeable even from a distance. Measured value, channel number, engineering units, day, time are displayed by the microprocessor based recorders and indicators for alarm, chart end and recording in progress are supported. Measured value and alarm active display are supported by a high resolution [1%] bar graph display. These compact microprocessor based recorders with splash-proof front door [ip 54] have been blueprinted with many yokogawa innovations like brushless dc servomotor, ultrasonic pen position sensing and high voltage solid state scanner. Microprocessor based recorders offers a variety of options including rs-422a communication, mathematical functions, ic memory card slot, alarm points up to 24 points and remote control.
