WB-98A Intelligent Indicator

The characteristic of our WB-98A intelligent indicator is as follows: 1·High accuracy, good stability. The indicator using a microprocessor core and automatic calibration circuit. Automatically calibrated to the analog circuit signal by the microprocessor. Using precision reference voltage regulator and has excellent source of long-term stability. The software technology guarantee the accuracy and reliability of the indicator in the widest effective measuring range. 2·Strong anti-jamming ability. As a result of double-integrating A/D convertor (sampling rate of 12.5 times/ second), the frequency and the high harmonics have stronge anti-jamming capability. A series of measures are adopted in the circuit design as well as the production craft, the indicator itself can be excluded from the power supply to a variety of interferenc, and it can exclude an impact of voltage fluctuations and intermittent power outages, these are able to ensure a long-term reliable operation without any human intervention.3·Using ultrahigh brightness LED digital tube display.4·A full function and easy expansion.5·Easy of maintenance, fully integrated circuits and using sockets to install, easy maintenance.6·This indicator can be equipped with a printer interface, and it can be matched with CASIO HR-8 printer which with a small calculator.There is an adjustable internal clock, it can show time when the indicator doesn’t work. The indicator is equipped with nickel-cadmium battery. When the indicator works normally, it can charge the battery. When power failure, the indicator automatically enter to maintain state, and the internal battery will maintain the clock work, it can be maintained for more than three months. When set in the fast measuring, the indicator can automatically print the value of measuring time and temperature.7·With isolated parallel BCD code output; 4 20mA (1 5v) analog output for the users to choose in order to match with large screen display or to send the measuring results to the machine.8·There’s calibration switching pathway on the internal motherboard of the indicator for users to choose. Each indicator can be matched with 4 different kinds of thermocouple.(B,S,R,WRe3/WRe25 or B,S,R,K) 9·The shell of the indicator is a closed structure. It has a long-term reliable operation in the industrial field under harsh environmental conditions.
