• Mount the sensor onto the false ceiling or shaft instead.

• Mark their locations visibly and record them in the site documentation.

Which of the following criteria is not a critical consideration before sensor mounting?

• Explosion protection

• Exposure to vibration

• Cost of the sensor installation.

• Min / Max. ambient temperature

What is the function of having a "drip loop"?

• To make the cable shorter.

• To create a loop to bypass the sensor housing

• To allow water from the housing to drip outwards.

• To prevent water from entering the sensor housing.

Sensor installation must be done in a way that _________________.

• It is easy.

• It can be hanged in any direction.

• It does not protrude in any direction.
