What Makes a Good Sensor?

I'd add

4. Environmental stability (repeatability under different conditions makes life so much easier)

5. Calibration

6. Durability (under necessary conditions of use - it's real tedious to have to change sensors because the old one is worn out)

4. Environmental Stability - It sounds like you may be referring to the Hysteresis. This defines the ability of the sensor to give the same output when the same increasing and then decreasing values are applied consecutively. Repeatability and hysteresis (including temperature hysteresis) define the basic stability of the device and their effects are not easily compensated. So, it is wise to take these into consideration when choosing a sensor.

"4. Environmental Stability -It sounds like you may be referring to the Hysteresis ... "

Doesn't sound like that to me - don't know who Guest is, but I thought they spelt it out quite succinctly ...

"4. Environmental stability (repeatability under different conditions makes life so much easier)"

Hysteresis is something different, to whit, the difference in output values when subjected to increasing and decreasing input levels. Agreed, the environmental conditions may have an effect on the hysteresis, among other performance parameters of the sensor.

Durability - particularly with strain-gauge pressure sensors. Failure analysis of damaged devices has revealed that the vast majority of failures resulted from being subjected to pressures greater than the absolute maximum pressure value; usually in the area of 2X the effective range. These excursions are often unavoidable. There would be a market for pressure sensors designed to sustain absolute maximum pressures 3-4X the effective range.

You need something which can adjust for some variation in input voltage... garbage in, garbage out.

Robustness!

Temperature compensated.

The one thing most people lose sight of is sensors are designed for specific pressure ranges and are calibrated for the pressures which are most important to monitor. Once you are out of that range, the repeatability goes down. So repeatable in the range defined by user.
