Device Classification
|
|
|
| |
Your choices are...
|
|
|
| |
Sensor
|
|
By our definition, a sensor is a transducer, its output is meant for processor, controller or data acquisition system. No display or user interface is present. If you desire a switch, choose this option.
|
| |
Sensor System
|
|
By our definition, a sensor system has more capability than a transducer. The unit may have a display and/or a user interface. If you desire a simple gauge, a locally programmable unit (stand-alone) or a controller/totalizer, choose this option.

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.
|
|
|
|
| |
Operating Distance Range:
|
|
The absolute maximum range over which the device can provide sensible readings.
|
| |
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.
