Amarnath Reddy I am a graduate in electrical engineering and blogger by passion. This is essential so that once the instrument has been calibrated on x 1 range, calibration of the x 0. Some of the features are explained below: This instrument has two ranges: The value of the optentiometer emf is obtained by adding the galvanometer reading to the main dial setting.

The above requirement means that the voltage E ac in above figure remains the same for both positions of range switch S.

The selector switch S is put in the calibrate position and the rheostat is adjusted so that there is no current flowing through the galvanometer. Laboratory-type or DC Crompton’s Potentiometer: Newer Post Older Post Home. There is also a single turn circular slide wire. The standardisation should be again checked after the completion of the measurement.

Single potengiometer potentiometer using independent calibrating circuit.

Potentiometer Working Principle of Potentiometer

Supposing the value of emf of the standard cell is 1. Number of Employees Upto 10 People. The switch S is then thrown to the operate position and unknown emf is read by adjusting the measuring circuit dial and slide wire.

Our company is devotedly engaged in supplying a wide assortment of Crompton Potentiometer that is designed using the latest technology. View Contact Call Seller Now. This potentiometer is supplied with a self standardization circuit built in, which renders standardization dependent on setting of voltage dials.

The design of circuit of a duo-range potentiometer should be such that it is possible to change the measuring ranges without re-adjusting the rheostat or changing the value of working voltage of the battery.

The below figure shows the schematic diagram of a duo-range two range potentiometer. This potentiometer is provided with a double throw switch which allows the connection of either the standard cell or the unknown emf to be applied to the working circuit. Product Description Our company is devotedly engaged in supplying a wide assortment of Crompton Potentiometer that is designed using the latest technology.

The value of the compensating resistors is such that the resistance of the potentiometer circuit, as viewed from terminals, where the unknown emf is applied, remains constant irrespective of the position of the sliding contacts.

DC Crompton’s Potentiometer or Laboratory Type Potentiometer

This fixes the working current to its proper value. The long slide wire is awkward, and even for the length shown cannot be read to a very great degree of precision. The vernier potentiometer reads to the increment of 0.

Ctompton potentiometer potentiometre supplied with a self standardization circuit built in, which renders However, in this potentiometerthere are three measuring dials. Final adjustments are made for zero deflection with the help of the rheostat. The negative battery terminals are connected together and positive battery terminals are also connected together through a galvanometer as shown in the figure below.

The moving arm of middle dial carries two arms spaced two studs apart. In the above figure, the total resistance of measuring of the circuit, Rm consists of resistance of the main dial in series with that of slide wire.

Crompton Potentiometer Complete Setup

The value of unknown emf is read off directly from the settings of the dial adjust slide wire. After completion of standardisation, the switch ‘S’ is thrown to operate position thereby connecting the unknown emf into the potentiometer circuit.
