variable inductance transducer definition

: …externally energized transducer, called the variable-reluctance type, is one in which the magnetic circuit is broken by an air gap. Transducer and Inverse Transducer. Another transducer for finding the linear displacement is the Linear Motion Variable Inductance Transducer. A schematic of the linear motion variable inductance transducer is shown below. The transducer is used with the carrier bridge amplifiers types IT 1-5-51 and IT 1-6-51, which operate at a carrier frequency of 2000 c. The cutoff frequencies of the transducer are 70 c for the + or - 3-g range and 100 c for the + or - 9-g range. Transducer – The device which converts the non-electrical quantity into an electric quantity is known as the transducer. The transducer comprises a cylindrical plastic bobbin on which an inductive coil is wound. VARIABLE-INDUCTANCE TRANSDUCERS • An inductive electromechanical transducer is a transducer which converts the physical motion into the change in inductance. Rotary Variable Inductive Transducers (RVITs) are a form of position sensor for non-contact rotary measurement. Operating from a single rail DC voltage supply, they provide either a ±3VDC (RVIT 15-60) or 4-20mA (RVIT 15-120i) output, over a 120 degree angular sensing range. The mechanical movement to be measured is used to change this air gap, thus changing the reluctance, or opposition, to the production of a magnetic field in the circuit. A variable inductance transducer for providing, via inductance modulation, an electrical output signal which is representative of a mechanical input signal. Digital Transducer – These transducers convert an input quantity into a digital signal or in the form of the pulse. This type of transducer is used for finding the linear displacement in terms of voltage or other digital parameters. (Rotary Variable Inductance Transducer) technology. 5. Variable Inductive Transducers . A variable inductance transducer for providing, via inductance modulation, an electrical output signal which is representative of a mechanical input signal. • Inductive transducers are mainly use for displacement measurement • In such a Transducer the pressure change causes change in the inductance of the sensing element. Google has not performed a legal analysis and makes no representation as to the accuracy of the status listed.) Prior art keywords plunger transducer ceramic sleeve core Prior art date 1989-12-08 Legal status (The legal status is an assumption and is not a legal conclusion. 5. RVITs have a solid track-record for reliable operation in tough conditions. The digital signals work on high or low power. LVDT (Linear Variable Differential Transformer) An LVDT, or Linear Variable Differential Transformer, is a transducer that converts a linear displacement or position from a mechanical reference (or zero) into a proportional electrical signal containing phase (for direction) and amplitude information (for distance). The RVIT design utilizes a set of four printed circuit coils and a light-weight conductive spoiler to achieve superior performance Other articles where Variable-reluctance transducer is discussed: telemetry: The transducer. This transducer is used for displacement measurement. 1. There are mainly two types of proximity inductance transducers.
