3030AN Honeywell VRS Series Magnetic Speed Sensor

Honeywell VRS Sensors_x000D_ 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._x000D_ 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._x000D_ Self-powered operation_x000D_ Direct conversion of actuator speed to output frequency_x000D_ Simple installation_x000D_ No moving parts_x000D_ Designed for use over a wide range of speeds_x000D_ Adaptable to a wide variety of configurations_x000D_ Customized VRS products for unique speed sensing applications_x000D_ Potential Applications:_x000D_ Engine RPM measurement_x000D_ Motor RPM measurement_x000D_ Process speed measurement_x000D_ Speed measurement of pumps, blowers, mixers, exhaust and ventilating fans_x000D_ Flow measurement on turbine meters_x000D_ Wheel-slip measurement on autos and locomotives_x000D_ Gear speed measurement_x000D_ Honeywell Magnetic Speed Sensor, 15kHz Maximum Operating Frequency, 28mm Thread Length - 3030AN_x000D_ Conveniently monitor the performance of your rotating devices with this magnetic speed sensor from Honeywell. Its housing contains a permanent magnet surrounded by a coil. It converts the magnetic field generated by the coil to a voltage reading that allows you to easily monitor the speed of your connected equipment. Thanks to its maximum operating frequency of 15kHz, this device is suitable for use in heavy-duty applications._x000D_ Features & Benefits_x000D_ • Wide operating temperature range between -55°C and +120°C for use in harsh conditions_x000D_ • Long thread length of 28mm for secure installation, even in high-vibration applications_x000D_ • Self-powered operation means there's no need for a external mains connection_x000D_ Applications_x000D_ • HVAC systems_x000D_ • Automotive industry_x000D_ • Wind turbines_x000D_ What's the advantage of a magnetic-type speed sensor?_x000D_ As magnetic speed sensors are non-contact devices, there's less risk of wear for a longer service life._x000D_ Magnetic Pick-Ups_x000D_ Miniature magnetic 'pick-up' transducers suitable for use in a wide range of sensing applications. Each device responds to movement of ferrous parts past the pole on the end of the unit. Used extensively in areas such as speed regulation of motors, when sensing for example, the teeth on a gear wheel. However, magnetic pick-ups may be used to implement feedback and control functions in many fields. Automotive applications include crank angle sensing, ignition timing, anti-skid systems and diagnostics. Applications in the computer peripherals area encompass disc drives, line printers, card punches/readers and printer terminals. The diagrams indicate the two basic modes of using these components. Note especially their small size in relation to their high signal output, enabling their deployment where many conventional sensors cannot be fitted. Fully encapsulated construction for reliable operation, but not intended for immersion in liquids.
