Rotary potentiometers and rheostats both use electrical resistance to regulate current flow in electrical circuits. The difference between the two devices lies in the type of resistance used and the way the element is adjusted. Both types of devices are used in a variety of applications, such as audio equipment, medical equipment, and industrial control systems. The RNS700 is a rotary potentiometer used in a wide variety of applications due to its highly adjustable characteristics.

The RNS700 is a multi-turn rotary potentiometer designed for use in high precision applications. It features a rotating shaft with a stepped adjustment knob and a high resolution contact system for matching current loads. The device operates on an internal voltage of 5 VDC and provides a range of electrical resistance from 0 ohms to 5 kilo ohms. The resistance is adjusted by turning the adjustment knob which moves the contact arm along the resistor track. The resistors are connected in series and the resistance is calculated by measuring the voltage drop across each resistor. The RNS700 has a wide range of applications such as setting the gain and bias of voltage controlled amplifiers, adjusting the set points of motor controllers, and controlling the temperature of liquid baths.

The working principle of the RNS700 is that it produces a specific amount of electric resistance, which is determined by the size of the gap between the contact arm and the resistor track. The adjustable arm is connected to a humanly adjustable knob, which when adjusted, changes the size of the gap and produces a corresponding amount of resistance. The device is designed such that small increments of adjustment produce a definite and predictable amount of resistance suitable for precision applications.

The RNS700 is an ideal choice for applications where precise control of electrical currents is desired. Its adjustable design makes it easy to quickly make minor adjustment, such as setting the bias of a transistor amplifier or the temperature of a liquid bath. Its high resolution contact system also ensures that current loads are matched properly. Furthermore, with its wide range of resistance values, the RNS700 can be used in a variety of applications from audio equipment to industrial control systems.
