N2402

The N2402 is an electronic torsiometer, listed in the 1st edition of the Agenda radioelectronistului (1983) among the instruments of IEMI and ICSITE in Bucharest [1].

The 1st edition of the Agenda radioelectronistului (1983) lists the „N-2402” („Torsiometru electronic”, electronic torsiometer) among the electronic instruments for measuring non-electrical quantities of the N-21…N-29 groups, whose producers it gives as „I.E.M.I., I.C.S.I.T.E.” (Bucharest); it does not say which of the two made it; a note says that with suitable torsiometric transducers (couplings), available in seven sizes, it is used to measure torque, delivered or absorbed power and rotational speed, in steady or slowly varying conditions [1]. Its table gives a torque of 0…10⁴ N·m, a power of 0…3·10³ kW, a rotational speed of 10²…6·10³ rpm, a 220 V (−15 %…+10 %) supply, at most 15 VA, an ambient temperature range of +5…+40 °C, 15 × 44 × 21 cm (height × width × depth) and at most 6.7 kg [1].
