Product Profile of Process / Temperature Instrument
VIRAL CONTROLS OFFERS A HIGHLY ACCURATE PROCESS/TEMPERATURE INSTRUMENT, WHICH IS EFFECTIVE IN CHECKING OUT MOST CALIBRATIONS. WITH A HIGH RESPONSIBILITY FACTOR, THE INSTRUMENT HANDLES THE WILDEST OPERATING VOLTAGE, 70 - 300V, 40 - 400HZ AC; 100 - 420V DC. ALL THE INPUT TERMINALS [T/C, RTD, MA, V, EXCITATION 24V] ARE FAULT PROTECTED INDEFINITELY UP TO 250V AC/DC, WHILE EACH UNIT IS SUBJECTED TO A FAILURE-FREE 168 HOURS BURN-IN. IT FULFILLS A CORRECTNESS OF FOUR DIGIT LINEARIZATION, RELATIVE ACCURACY: 0.03 PERCENT. THE SUB SURFACE DIE HEATED ZENER REFERENCE [20PPM/1KHR] AND 10PPM/?C GAIN RESISTORS PROVIDE UNMATCHED STABILITY WITH TIME AND TEMPERATURE. THE REFERENCE AND GAIN RESISTORS PRE-STABILISED BY 168 HOUR BURN-IN. THE INSTRUMENT DEMONSTRATES STABLE READINGS WITH SUPERIMPOSED AC [NMRR TYPICAL 120DB] AND SPIKES.
