Temperature Range vs Field-of-View table
Output table
e.g. model PC151hT-4 has a 15:1 field of view and provides a type k thermocouple output representing
target temperatures of 0ºC to 500ºC plus a 4-20 mA output proportional to internal sensor temperature. For
simplicity, the sensor temperature range is always set the same as the target temperature range

All PyroCouple sensors are fitted
with precision germanium lenses for
accurate optics. model PC21 has
2:1 optics making it suitable for most
applications where the sensor can be
mounted close to the target. Model
PC151 is designed for small or distant
targets and has an optical resolution
of 15:1. model PC301 is designed for
very small or distant targets and has an
optical resolution of 30:1.
These compact sensors are small
enough to fit almost anywhere and
their rugged stainless steel housings
make them ideal for applications
where cleanliness and hygiene are
paramount.

withstand ambient temperatures which exceed
the normal 70°C limit. Air or water (depending
on the degree of cooling required) flows into
one of the fittings on the side and out of the
other. To prevent condensation forming on the
lens, the air/water cooled housing is supplied
complete with an air purge collar. Please note,
the air/water cooled housing must be ordered
with the sensor and cannot be fitted by the
user.
