Transportation Variable Reluctance Speed Sensors 32303003 Thrumold Series Issue A Datasheet FEATURES Configurable diameters, materials, and output voltages: A variety of package styles, housing diameters, materials and and output voltages Compensated operating temperature range: -40 C to 150 C -40 F to 302 F Energy efficient: When used in engine camshaft and crankshaft applications, can provide a precise engine timing signal to optimize the combustion process No moving parts or wear mechanisms (unlike mechanical switches) Self-powered operation: Can be used in applications where no external power is available Direct conversion of actuator speed to output frequency: Simplifies the customers electronic control interface because each output signal correlates to each tooth on the actuator DESCRIPTION Simple installation: Screw-in mount sensor requires no special The Thrumold Series VRS (Variable Reluctance Speed) sensors tools are designed to detect engine timing and transmission speed Designed for use over a wide range of speeds: Allows for by determining the speed and position of rotating shafts in potential use in engines and transmissions which often require heavy-duty, off-road, and construction vehicles, providing a wide range of rotational speed measurement information to help improve engine combustion process Durable: 300 Series stainless steel housing material allows for efficiency. These passive VRS sensors are simple, rugged use in harsh environments devices that do not require an external voltage source for Environmentally tough: operation. A permanent magnet in the sensor establishes a - Chemical compatibility: Engine oil, diesel fuel, water, engine fixed magnetic field. The approach and passing of a ferrous coolant, salt spray and trisodium phosphate cleaning metal target near the sensors pole piece (sensing area) solution (oils containing extreme pressure additives are not changes the flux of the magnetic field, dynamically changing suitable for use with this sensor) its strength. This change in magnetic field strength induces - Front end sealed to 5 psi a current into a coil winding which is attached to the output Sensor reach options: Sensor reach is the distance from a terminals. The output signal of a VRS sensor is an ac voltage sensors mounting surface to its sensing tip: that varies in amplitude and frequency as the speed of the - Adjustable: The sensor, with its threaded housing, is monitored device changes, and is usually expressed in peak to screwed into the application until it makes contact with the peak voltage (Vp-p). One complete cycle occurs as each tooth target, and then is backed off one-half to one turn a user- passes the sensors pole piece. If a standard gear were used provided jam nut is then used to fix the sensor in place as a target, this output signal would resemble a sine wave if - Fixed (also called non-adjustable): The sensor is screwed viewed on an oscilloscope. into the application until the sensors mounting surface makes contact with the applications mounting surface VALUE TO CUSTOMERS Cost-effective: Self-powered operation, energy efficiency, and POTENTIAL TRANSPORTATION APPLICATIONS simple design help to reduce costs Engine timing for heavy duty, off-road, construction vehicles Manufacturing excellence: Honeywell has more than 100 years (i.e., tractors and dump trucks) of manufacturing and engineering expertise Transmission speed for heavy duty, off-road, construction Fast Request for Quotes (RFQs): Responding quickly to RFQs vehicles (i.e., tractors and dump trucks) and product sample requests are Honeywell hallmarks Reliable supply chain: Honeywells effective inventory Note: Not recommended for potential use in Aerospace/ management and dependable supply chain are available Defense applications. throughout the customers development cycle Designed to Six Sigma standards: Provides the highest level of PORTFOLIO product quality, performance, consistency and confidence that In addition to the Thrumold Series for Transportation the sensor will perform to specification applications, Honeywell offers Industrial variable reluctance Dedicated teams and efficient manufacturing processes allow sensors which provide electrical compatibility to most samples to be shipped quickly to support the customers control system interfaces: VRS General Purpose Series, VRS product development cycle Hazardous Location Series, VRS High Output Series, VRS High Resolution Series, VRS High Temperature Series and VRS Power Output Series.
