Frequently Asked Questions (FAQs)

1. Why voltage transducer is used?

A voltage transducer might be used with a DC motor. A voltage transducer is an element of electrical circuitry that both measures and monitors the levels of current and voltage dispersed and dispensed through the circuit, depending on whether the current is AC or DC.

2. What is DC voltage transducer?

DC Voltage Transducers and Transmitters are designed to provide an output DC signal that is proportional to the input DC voltage. These devices are especially suited for applications with a current shunt to monitor DC current.

3. What is potential transducer?

A transducer is a device that converts one form of energy to another. Usually a transducer converts a signal in one form of energy to a signal in another. Potential Transducer : PT88P01. The PT88P01 3-Wire Potential Transmitter produce a calibrated 4-20 mA DC signal that is proportional to the True RMS input AC voltage.

4. What is the purpose of a transducer?

A transducer converts some sort of energy to sound (source) or converts sound energy (receiver) to an electrical signal.
