The installation process consists of the following stages:
Preparation
Please read the following sections thoroughly before proceeding with the installation.
preparation
Ensure that the sensor is positioned so that it is focused on the target only.
DiStance anD Spot Size
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.
ambient temperature
The sensor is designed to operate in ambient temperatures from 0°C to 70°C.
Avoid thermal shock. Allow 20 minutes for the unit to adjust to large changes in ambient tem-
perature.
atmoSpHeric QuaLity
Smoke, fumes or dust can contaminate the lens and cause errors in temperature measurement.
In these types of environment the air purge collar should be used to help keep the lens clean.
eLectricaL interference
To minimise electromagnetic interference or 'noise', the sensor should be mounted away from
motors, generators and such like.
Wiring
Check the distance between the sensor and the indicating/controlling device. If necessary, the
PyroCouple M sensor can be ordered with a longer cable attached.
poWer SuppLy
Be sure to use a 24Vdc, (25mA) power supply.
