3. Instrument and environment

Generally speaking, operating precautions (mounting, positioning, cleanliness) are essential in most circumstances. Nonetheless, measuring equipment, particularly in industrial environments, is often subjected to harsh environmental conditions (temperature rise, water hammer, vibration, humidity, corrosive atmosphere, electrical or electromagnetic interference, etc.), and requires reinforced protection by various mechanical or electrical accessories. In cases where the safety of equipment and/or people is at stake, explosion-proof and/or intrinsic safety regulations must be complied with.

As the same causes lead to the same effects, all the recommendations and precautions that follow apply equally to mechanical pressure gauges, sensors and transmitters.
