In eighties, contact transducers became very commonplace and you must have seen them as tape heads in cassette players. Transducers are voltage-output devices that can be used with simple signal conditioning but are more sensitive to electromagnetic interference.The electrical resistance of the connecting cable can cause significant errors if the cable is long. While a sensor is a device that, as its name signifies, measures a physical quantity and then converts it into signals that can be read by the user or by any other instrument. Transducers are parts of more complex devices and are used to convert energy from one form to another. A 3-wire transmitter is used when an output of 0-20mA is required. 43 0 obj <>stream • A transmitter is a device dedicated to emitting electromagnetic signals corresponding to the given electric signal whereas transducers are devices to transform energy from one form to another. Transducers . These transducers effectively measured energy in the form of sound, pressure or any other type of mechanical energy. To help select the right sensor for a given task, their strengths and weaknesses can be summarised as follows: The words sensor, transducer and transmitter are often used interchangeably. • The transmitter is also a type of transducers. The sensor senses the physical change across the surrounding whereas the transducer transforms the one form of energy into another. Things become complicating for many when they see many sensors utilizing contact transducers in order to detect energy levels and then converting them into electrical energy that influences a display meter. this can be RS 485, 4–20 ma, CAN Bus, wireless or any other method that will get the signal to the appropriate place. The primary function of the sensor is to sense the physical changes, whereas the transducer converts the physical quantities into an electrical signal. This page compares Sensor vs Transducer and mentions difference between Sensor vs Transducer. The sensor primarily functions to sense physical changes in the environment; on the other hand, a transducer is used for converting physical quantities into electrical signals. Last month, we posted article to explain the relationship between pressure transducer and pressure transmitter, if you are not very clear and intent to learn the details, please check transducer v.s transmitter v.s sensor.. Or we are wrapping things up below for your short review. The sensor is a transducer that is used to change the amount of magnetic, mechanical, heat, light, chemical electric be current or voltage. The O/P signal is directed to any device that takes it and uses to alter the pressure in a system. The following are the key differences between the sensor and transducer. Paintbrush transducers are just like immersion transducers except that they work in air.
