Technology
           
   Your choices are...         
   Cable Extension       For cable extension devices, moving object is attached to a cable, which is typically connected to a potentiometer. As the object moves, the potentiometer's resistance value changes. 
   Magnetic Induction       Magnetic induction sensors are a non-contact technology type of sensor that relies on an induced current from a magnetic field to measure the linear velocity. 
   Microwave       Sensor uses microwave technology to determine speed. 
   Optical / Laser       Sensor uses fiber optics or laser technology to determine speed. 
   Piezoelectric       For piezoelectric devices, a piezoelectric material is compressed and generates a charge, which is measured by a charge amplifier.  Often used in vibration velocity measurement applications. 
   Radar / Radio Frequency       Sensor emits radar wave, which is reflected by surface and returned to sensor. Speed is determined by measuring frequency difference (Doppler Effect). 
   Strain Gauge       For strain gage devices, strain gages (strain-sensitive variable resistors) are bonded to parts of the structure, which deform when making the measurement. These strain gages are typically used as elements in a Wheatstone bridge circuit, which is used to make the measurement. 
   Ultrasonic       Sensor emits an ultrasonic pulse, which is reflected by surface and returned to sensor. Speed is determined by measuring frequency difference (Doppler Effect). 
   Other       Other unlisted, specialized, or proprietary technology. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Electrical Output / Interface
          The type of electrical signal that will be produced.
   Your choices are...         
   Voltage       Output voltage is a simple (usually linear) function of the velocity measurement. 
   Current       Analog current output such as 0-20mA, 4-20 mA, etc.; often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals long distances. 
   RF / Radio       The output signal is encoded in radio frequency and transmitted wirelessly to a receiver. 
   Switch / Alarm       An output of a change in state of switches; includes alarm switching or triggering. 
   Serial       A standard digital output protocol (serial) such as RS232, RS422, RS485, or USB. 
   Parallel       A standard digital output protocol (parallel) such as IEEE488, etc. 
   DeviceNet       Utilizing CAN protocol, DeviceNet is a network designed to connect industrial devices such as limit switches, photoelectric cells, valve manifolds, motor starters, drives, and operator displays to PLCs and PCs. 
   Ethernet       A local-area network (LAN) protocol developed by Xerox Corporation in cooperation with DEC and Intel in 1976. Ethernet uses a bus or star topology and supports data transfer rates of 10 Mbps. The Ethernet specification served as the basis for the IEEE 802.3 standard, which specifies the physical and lower software layers. Ethernet uses the CSMA/CD access method to handle simultaneous demands. It is one of the most widely implemented LAN standards. 
   SERCOS       (SErial Real-time COmmunications System) is an open controller-to-intelligent digital drive interface specification, designed for high-speed serial communication of standardized closed-loop data in real-time over a noise-immune, fiber optic cable. 
   SSI       Serial Synchronous Interface (SSI). A general standard for absolute encoders. The physical interface consists of two differential connections aside from power and ground. The controller provides a clock input, and the sensor returns a data signal synchronized to the clock. 
   TTL Compatible       Transistor-to-transistor logic (TTL) consists of multiple transistors forming logic gates for conditional switch output.  TTL Compatible refers to a logical output of 1 for voltages 2.4V to 5.5V, and a logical output of 0 for voltage levels from 0 to 0.6V. 
   Other       Other unlisted, specialized, or proprietary electrical output or interface. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Device Category
          The purpose of this question is to separate items into general categories based upon what the item is designed to do, or the manner in which it is used.
   Your choices are...         
   Sensor Element / Chip       Denotes a raw sensor element with no packaging or signal conditioning. 
   Sensor / Transducer       A more complex device with packaging and/or signal conditioning that is powered and provides an output such as DC volts, 4-20mA, etc. 
   Instrument / Meter       Typically a self-contained unit that provides an output such as a display on or near the device. Usually also includes signal processing / conditioning. 
   Gauge / Indicator       A device, which typically has an analog display such as a needle and no electronic output. 
   Recorder / Totalizer       More complex device that records, totalizes, and/or analyzes measurement data.  May have a computer interface.
