3.2 Ambient Temperature
The Sensing head can operate in an ambient temperature of 0 to 70°C (32
to 158°F). The Sensing head in the high temperature model (-HT) can
operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any
cooling required. The Sensing head can operate up to 200°C (392°F) using
the water cool jacket accessory OS100-WC (See Fig. 3-6).
There is a warm up period of 3 minutes after power up. After the warm
up period, temperature measurement can be made.
When the ambient temperature around the sensor head changes abruptly,
the sensor head goes through thermal shock. It takes a certain amount of
time for the sensor head to stabilize to the new ambient temperature. For
example, it takes about 30 minutes for the sensor head to stabilize going
from 25°C to 50°C (77 to 122°F) ambient temperature.
The sensor head dimensions are shown in Fig. 3-2.
