N 23-100

The N 23-100 is a programmable automatic strain gauge installation for consecutive measurement of mechanical quantities at 100 points, made in the microproduction workshop of the ICE research institute in Bucharest, where it was designed [1]. Together with the N 23-50, 10 units were exported to East Germany [1]. In 1986 ICE’s prototype section had a firm contract to export one to East Germany, worth 78,000 roubles [2].

ICE’s laboratory for electronic instruments for measuring non-electrical quantities designed approved prototypes for many branches of the economy: strain gauge equipment (some configurations were exported to East Germany in 1971–1974 and 1977–1989), vibration meters, dimensional gauges, ultrasonic non-destructive testers, geophysical well-logging equipment and railway equipment [1]. Its designs were made in series at IEMI (27 types) and at the Precision Mechanics Enterprise (5 types), or in ICE’s microproduction workshop (45 types) for small series and one-off models [1].

IEI’s catalogue of civilian products also lists it [3].

ICE’s list of microproduction describes its automatic strain gauge systems for 100 and 1,000 points as meant for analysing the structures of buildings and bridges [4].
