DISTANCE AN D S POT S IZE
The size of the area (spot size) to be measured determines the distance between the sensor and
the target. The spot size must not be larger than the target. The sensor should be mounted so
that the measured spot size is smaller than the target.
AM BIENT TE MPERATURE
The sensor is designed to operate in ambient temperatures from 0°C to 70°C. For ambient tem
peratures above 70°C, an air/water-cooled housing will be required.
Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient tem
perature.
ATMOSPHERIC QUALITY
S m k o , e u f m s e r o
In these types of environment the air purge collar should be used to help keep the lens clean.
E LECTRICAL INTERFERENCE
To minimise electromagnetic interference or 'noise', the sensor should be mounted away from
motors, generators and such like.
WIRIN G
Check the distance between the sensor and the indicating/controlling device. If necessary, the
PCE-IR 50 sensor can be ordered with a longer cable attached.
P OWER S UPPLY
Be sure to use a 24 V DC (25 mA) power supply.
MEC HANICAL IN S TALLATION
All sensors come with a 1m cable and a mounting nut. The sensor can be mounted on brackets
or cut outs of your own design, or you can use the xed and adjustable mounting bracket acces
sories which are shown below. Note: The sensor housing must be connected to earth at one point,
either the cable shield termination or the sensor housing.
