Speed Sensing Relays

Rishabh Instruments Pvt Ltd offers Speed Sensing Relays that provide three user adjustable trip levels with LED relay state indication and a speed indicator output signal. The trip functions provided are: SPl disengages the crank starter; SP2 energies protection or under speed alarm; and SP3 alarms or trips on over speed. The unit also incorporates the following protection features: open circuit sensor detection – a break in the sensor lead will de-energise the over-speed relay; zero reset cranking – the crank relay will only re-set when the in-put frequency falls below 20% of the crank set point. Rishabh Instruments Pvt Ltd has built its core competence in manufacturing, design and development of test and measuring instruments and industrial control products on strong fundamentals; in terms of people, infrastructure and financials. The company provides a hands-on, value driven, professional environment considering people its most important asset. Starting in the late 1990s when the electro-mechanical era started shifting towards digital, the company began manufacturing digital panel meters, transducers, and a range of test and measuring products like multimeters and insulation testers, with technology collaboration from European partners. In 2011, it acquired Lumel S.A of Poalnd and the synergies of the joint unit have turned out to be game changer for both organisations.
