Sensor Type




           
   Your choices are...
 
      
 
   Dial Thermometer
 
     Dial thermometers are bimetal, gas-actuated, and vapor-tension-based. These thermometers display temperature, possibly min/max readings, and/or other 'extras'.
 
   Industrial Thermometer
 
     Industrial thermometers are basic bulb style thermometers designed for use in many industrial applications.
 
   Noncontact Infrared Temperature Sensor
 
     Non-contact temperature sensing devices are typically infrared temperature sensors.
 
   Laboratory Thermometer
 
     Laboratory thermometers are used to measure temperatures or temperature changes with a high degree of precision.
 
   RTD Element
 
     RTD (resistive temperature device) elements are wire windings or other thin-film serpentines that exhibit changes in resistance with changes in temperature. 
 
   Thermistor Element
 
     Thermistor elements are thermally-sensitive devices whose electrical resistance varies with temperature.
 
   Thermocouple Element
 
     Thermocouple elements are temperature sensors that are useful over a wide range of temperatures.  Thermocouples are formed by two dissimilar metals.
 
   Temperature Probe
 
     Temperature probes may be used for various temperature sensing applications. These sensors are configured with a variety of temperature sensors including: thermocouples, RTDs, or thermistors.
 
   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.
Sensed/Displayed Temperature




   Measurement/Display Range (°F)
 
     Temperature range in °F to be sensed or monitored.
 
   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.
           
   Allowable Sensor Over-Range
 
     Overrange specification limits the range of matching products to the specified range multiplied by a selected overrange factor. This keeps returned matches close to the range requirement and filters out products with a wider range than needed. "From", "To", and "Overrange" must all be specified to activate this option.

Example: User specifies a sensor with a range from 0-100. Without overrange specification, sensors with ranges of 0-100, 0-1000, and -10,000 to +10,000 are returned as matches. An overrange specification of 50% will filter out any sensors with a full scale range greater than 150.
 

   Search Logic:      Matching products will have a range within the specified overrange limit.
   Measurement/Display Range (°C)
 
     Temperature range in °C to be sensed or monitored.
 
   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.
           
   Allowable Sensor Over-Range
 
     Overrange specification limits the range of matching products to the specified range multiplied by a selected overrange factor. This keeps returned matches close to the range requirement and filters out products with a wider range than needed. "From", "To", and "Overrange" must all be specified to activate this option.

Example: User specifies a sensor with a range from 0-100. Without overrange specification, sensors with ranges of 0-100, 0-1000, and -10,000 to +10,000 are returned as matches. An overrange specification of 50% will filter out any sensors with a full scale range greater than 150.
 

   Search Logic:      Matching products will have a range within the specified overrange limit.
   Thermocouple Type       
   Your choices are...
 
      
 
   E (-270°C - 1000°C)
 
     Chromel / Constantan; Typical temperature range of (-270°C - 1000°C).

     Nicrosil / Nisil; Typical temperature range of (-270°C - 1300°C).
 
   T (-270°C - 400°C)
 
     Copper / Constantan; Typical temperature range of (-270°C - 400°C).
 
   B (0°C - 1820°C)
 
     Platinum (30%) / Rhodium; Typical temperature range of (0°C - 1820°C).
 
   S (-50°C - 1768°C)
 
     Platinum (10%) / Rhodium; Typical temperature range of (-50°C - 1768°C).
 
   R (-50°C - 1768°C)
 
     Platinum (13%) / Rhodium; Typical temperature range of (-50°C - 1768°C).
 
   W (0°C - 2300°C)
 
     Tungsten / Rhenium; Typical temperature range of (0°C - 2300°C).
 
   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.
