크기 = 19.05 (Dia.) x 63.88 mm Honeywell VRS Sensors. Honeywell offers VRS sensors for high output, general purpose, power output, high resolution, high temperature, and hazardous location applications. High Output VRS sensors are designed for use in applications where higher output voltages are needed. For best performance use in applications of low to medium speeds with medium to high impedance loads. General Purpose VRS sensors are designed for use in applications with medium to high speeds or in electrically noisy environments with relatively small air gaps. Passive Front-End Sealed versions are available for use where the sensor is exposed to fluids, lubricants or adverse environmental conditions. VRS (Variable Reluctance Speed) Magnetic Speed sensors are simple, rugged devices that do not require an external voltage source for operation. The fixed magnetic field is established by use of a permanent magnet. As a ferrous metal object approaches and passes near the sensing area the flux lines of the magnetic field change in strength. This change in magnetic field strength induces a current into a coil winding, which is attached to the output terminals. The output signal of a VRS sensor is an ac voltage that varies in amplitude and wave frequency as the speed of the monitored device changes, and is usually expressed in peak to peak voltage. One complete waveform occurs as each target passes the sensor ??s pole piece. If a standard gear were used as a target, this output signal would resemble a sine wave if viewed on an oscilloscope. Self-powered operation Direct conversion of actuator speed to output frequency Simple installation No moving parts Designed for use over a wide range of speeds Adaptable to a wide variety of configurations Customized VRS products for unique speed sensing applications. Potential Applications: Engine RPM measurement Motor RPM measurement Process speed measurement Speed measurement of pumps, blowers, mixers, exhaust and ventilating fans Flow measurement on turbine meters Wheel-slip measurement on autos and locomotives Gear speed measurement
