The PyroCouple Series is a range of
high quality, low cost, compact sensors
which measure the temperature of
inaccessible or moving objects and
materials. They measure temperatures
from -20°C to 500°C, accurately and
consistently, with an outstanding
response time of 240 ms.
PyroCouple sensors are available as
either two-wire or four-wire units.
Two-wire PyroCouple sensors transmit
the target temperature as a 4-20 mA
output and offer a simple solution
for most non-contact temperature
measurement applications.
Four-wire PyroCouple sensors transmit
the target temperature as a 0-50 mV
or thermocouple output (type J, K or T)
plus the internal sensor temperature as
a 4-20 mA output. This second output
can be used to ensure that the sensor
is being operated within the correct
ambient temperature limits and prevent
damage caused by overheating or
overcooling. It can also be used to give
an approximate indication of the air
temperature surrounding the sensor.
