Rheostat Loading 'Abron' Double Tube

AP-894

Basic Structure : Double Tube Rheostats are either connected in parallel or in series These Rheostats are fitted with four pairs of terminals, one at the slider, For using it in series (twice the resistance) the clamp is removed Basic Structure :Double Tube Rheostats are either connected in parallel or in series as shown in the illustration above.These Rheostats are fitted with four pairs of terminals, one at the slider, one at one end of the tubes(both tubes are short-circuited) and two at the other end of the tubes with a movable conductor. Thus these types of Rheostats can be used in parallel giving half the resistance than the single tube Rheostats, but twice the resistance by connecting the single terminal at the base and terminal at the slider. For using it in series(twice the resistance) the clamp is removed from the two terminals at the base. These two terminals are then used and variation can be taken by sliding the contact.

Rheostat Loading 'Abron' Multiple Tube Dia 506 Cm 2 1/4"

AP-895

For Engineering Laboratories. Eureka wire wound on special non-magnetic pipes in grooves.The Resistance are mounted in Vertical Array in a box made of sturdy angle iron frame and perforated metal sheet*The live portion of the unit is completely insulated from the body. The whole is mounted on four castor wheels for easy transportation from one place to another in the laboratory.A-panel with controlling switches,fuses and terminals for connections is fitted on the front sides of the box. These Loading Rheostats are fitted with heavy duty porcelain based tubular switches for having the load in equal steps. A control switch with fuses or AN MCB and two insulated terminals are provided for connections Voltage in all the cases 250 Volts, AC (At 220 Volts AC the prices will be the same). For DC heavy duty knife switches

Rheostats

AP-893

Rheostats, Open type Single tube : Rheostats are made with a variety of resistance & current carrying capacity so as to satisfy every need. They are wound with heavely oxodised eurika resistance wire upon a porcelene tube dia 44 mm aprox. The tube is carrying upon bakalite ridder and the heavy duty sliding contact is of the phospor bronze with brass rod. 4 mm socket terminals are fitted, allowing for rheostat or potentiometer connection.

Total resistance and maximum current capacity is marked on the slidder. Total Permanent current loading should not exceed 75% of the marked values.Accuracy : The actual resistance of Rheostat shall be +20% -5% of the rated resistance as per our resistance chart. (as per ISI specification no. IS : 9051 S. No. 10.3)
