Instrumental electronics offers a digital temperature indicating controller, series 71000. It is housed in a 96 x 96 x 150 mm plastic enclosure, and is suitable for indicating/controlling temperatures with sensors such as resistance bulbs [pt-100], thermocouples [j, k, r and s], mv, ma, etc. The display is four digit, 12.5 mm height, red or green led with resolution of 0.1oc up to 1000oc, and 1oc above 1000oc. Accuracy is better than 0.5% of full scale +1 digit. Power supply required is 240 v ac +10%, or 110 v ac +10%, 50 hz. Suitable sensors [rtds thermocouples] are also available along with the temperature indicator. Control output is either on/off or proportional with relay of contact rating 6 a, 230 v, resistive. Control set point setting is with the help of push button and 10-turn fine and coarse trim pots. For proportional type reset, adjustment is available on the front panel. Controllers with two set points are also available; out of these two set points both could be on/off or one on/off and other proportional, or both proportional.
