Device Type
   Device Type      Think of products as belonging to general categories based on what they are designed to do and how they will be used. The 'category' criteria attempts to distinguish 'unpacked' sensors that might be used as part of a larger sensor from, say, a gauge which can be read just by looking at it.
   Your choices are...         
   Angular Accelerometer       A device that measures the rotational or angular acceleration of a rotating body. 
   Linear Accelerometer       Accelerometers are sensors and instruments for measuring, displaying, and analyzing acceleration and vibration. They can be used on a stand-alone basis or in conjunction with a data acquisition system. 
   Sensor / Transducer       Devices are either a raw sensor or more complex transducer. Transducers can communicate either by voltage or current loop. 
   Gauge / Indicator       Gauges are devices which have a display, but no electronic output.  
   Instrument / Meter / Analyzer       Instruments, meters, and analyzers are devices that are (usually) self-contained units that provide an output (typically a display) locally, at or near the device. Typically, these devices also include signal processing or conditioning. 
   Recorder / Totalizer       Devices record measured values or accumulate totals. 
   Switch       Switch devices either make or break contact when a certain activation or vibration level is achieved. 
   Transmitter       Transmitters are more complex, include packaging and/or powered signal conditioning, and produce an output such as DC voltage, 4-20mA, etc. 
   Other       Other unspecified or proprietary devices. 
   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.

Specifications
   Acceleration       Instruments that do not have integrated or associated sensors do not have a rated acceleration value. Searching by acceleration yields possible matches for those items. Enter the maximum acceleration to measure. One 'g' is the gravity on earth: 32.2 ft/sec2 or 9.8m/s2
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Angular Acceleration       This is the input range is for angular accelerometers only. These devices measure the angular rate of change per second squared in a rotating body. The typical unit of measure is radians/sec^2. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Linear Velocity       The maximum range within which devices can operate. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Frequency Range       The frequency range of interest. Enter "0" for DC response. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
   Proximity / Displacement Range       Proximity or displacement range is the measurement range of the sensor in the linear region, i.e., where the output varies consistently with the measured distance or displacement. 
   Search Logic:      User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
   Minimum Accuracy       The minimum acceptable accuracy.   
   Search Logic:      All matching products will have a value less than or equal to the specified value.
   Number of Input Channels       The number of inputs accepted by the instrument or meter. 
   Search Logic:      All matching products will have a value greater than or equal to the specified value.

Number of Axes
   Number of Axes       
   Your choices are...         
   Single Axis       Devices are capable of measurement on only one axis. 
   Biaxial       Devices are capable of measurement along two, usually orthogonal, axes. 
   Triaxial       Devices are capable of measurement along three, usually orthogonal, axes presented as X, Y, and Z. 
   Search Logic:      Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Form Factor
   Instrument Type       
   Your choices are...         
   Handheld       Devices are designed to be operated while held in one hand. 
   Modular       Devices have different modules for interfacing to different sensors or input ranges. 
   Portable       Devices have handles, cases, wheels, etc. for portability, but are not necessarily held in the hand during use. 
   Stand Alone       Devices perform all data processing internally. 
   Other       Other unlisted or proprietary instrument types. 
   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.

Features
   Features       
   Your choices are...         
   Battery Powered       Batteries supply the main power for the device operation. This is not for backup supply. 
   Corrosion Resistant       Corrosion-resistant alloys can be formulated for a wide range of aggressive well bore conditions. However, cost generally determines the viability of any particular completion design. Alloys with high chrome content are commonly used for tubing strings. 
   Event Triggered       Device can be set to capture/log data when an event happens. 
   Explosion Proof         
   Filters       Devices are equipped with special signal processing or filtering (Butterworth, Bessel, etc). 
   Integrated Electronics Piezo Electric (IEPE)       Integrated electronics piezo electric accelerometers conform to the IEPE standard and have a piezo device inside that isolates it from the outside environment. Proprietary names for the IEPE standard include ICP®, CCLD, Isotron®, Deltratron®, Piezotron®, and others. 
   Intrinsically Safe       Intrinsically safe (IS) is an adjective for equipment and wiring which is incapable of releasing sufficient electrical or thermal energy under normal or abnormal conditions to cause ignition of a specific hazardous atmospheric mixture in its most ignited concentration. The IS terminations and wiring may be brought into any hazardous location of any group classification for which it is accepted without requiring explosion proof housing or other means of protection. 
   Radiation Hardened       Radiation-hardened devices are constructed of materials designed to withstand high-energy gamma radiation. Ratings are expressed in units such as permissible rads in total accumulated dose (TAD). 
   Sealed       Sealed units provide constant operating conditions. 
   Self Test / Diagnostics / Self Calibrating       The instrument has self-test or diagnostic ability. 
   Self Generating       The device requires no external power supply for operation. 
   Other       Other unlisted or proprietary features. 
   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.
