SALIENT FEATURES :

Universal Test Bench for speed measurement demonstrates the basic fundamentals of the various methods of speed measurment using various different speed transducers.

The Universal Test Bench comprises of variac, universal motor and a guide bracket on which impulse wheel / sensing flange is fitted. Variac plays the main role by varying the voltage to drive the system. These speeds are further transmitted by using step-pulleys driven with the help of rubber ‘O’ rings.

Three different transducers i.e. Magnetic Pick-up, Inductive Proximity Switch and Infra Red Sensor can be used to sense the speed and indicate on the same display with help of selector switch to read the speed in terms of RPM. Impulse wheel or sensing wheel is made in such a way that all transducers can sense at a time because the three sensors have different properties / characters i.e. Magnetic Pick up will sense only ferrous material, Inductive Proximity switch will sense all metals (any metalic Particle) and infra-Red sensor will sense reflecting stickers (reflection of light).

Arrangements are made to easily assemble, dissemble and interchange the transducers as and when required making the Universal Test Bench for Speed Measurement user friendly and convinent to use. Speed can also be measured with the help of analog tachometer by using AC Tacho Generator as a sensor and can also measure D.C. Voltage of D.C. Tacho Generator with the help of Digital Volt Meter (DVM).

A wide selection of other various tranducers and attachments are provided making the unit completely self contained to master various methods of speed measurement.
