> Home > Sensing Solutions > Checklist page 2

For any sensing application various properties within the target area will change while the target event occurs.

The choice of sensing technique to detect or measure the event will be one that gives sufficient percentage change in response to the event yet whose sensitivity, stability and clarity is least corrupted or compromised by other influences in the environment.

Further requirements may include the need not to interfere with other systems or sensors, or be detected by, or interfere with, other sensing systems operating in the same environment. Levels of accuracy required and budget may also play a part in determining optimum solutions.

Relevant Terms:
Operating range
Hysteresis (differential Travel)
Response time
Maximum switching frequency
Mark to space ratio
Time delay before availability
Off-state current
Minimum operational current
No load supply current
Temperature stability
Vacuum or pressure levels
EMC Susceptibility
Noise immunity
MTBF mean time between failure
Intrinsic safety
Radiation resistance
