Control Technology manufactures a digital strip chart recorder, CT SCR 80. Generally the strip chart recorders currently in use, are plagued by the doubtful reliability of their writing medium - ink pen, ink stylus, etc.However, this Digital Strip Chart Recorder addresses the reliability issue by using a standard, easily available, rugged and cost effective dot matrix printer as the writing medium. The recorder can be configured to accept any type of input, eg, output from a load cell, pressure transducer, thermocouple, RTD, etc. The analog signal is digitised using a precision ADC, stored for a specified length of time and plotted once every 30 minutes. The chart is plotted on plain paper using a standard dot matrix printer like TVS NOVO 130, TVS MSP 240, Epson LX 80, etc. The printer will be On only during the printing/ plotting operation. In addition to the parameter being plotted, the chart also provides real time data. The chart length is fixed as 210 mm.
