The connection of an HP 65 pocket calculator as a microprocessor in a control loop
The addition of an artificial odour (THT) to natural gas is controlled by automatic equipment built round a Hewlett-Packard HP 65 pocket calculator so achieving a price about one-tenth that of conventional installations. There are two identical controllers, each consisting of an electrochemical chromatograph, a digital voltmeter, setting dials, the calculator, and four input-output cards. The gas is sampled every ten minutes, but once an hour a sample of standard gas is substituted for the gas under control in order to calibrate the equipment.
