The PyroEpsilon 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.
PyroEpsilon sensors transmit the target
temperature as a 4-20 mA output and offer
a simple solution for most non-contact
temperature measurement applications.
The sensor’s emissivity setting can be
adjusted from 0.2 to 1.0 to cope with
different target materials and is controlled
by a 4-20 mA input. This gives the
opportunity to adjust the emissivity setting
automatically from a programmable logic
controller (PLC). Alternatively the emissivity
setting can be adjusted manually using the
optional PyroTune module. If the 4-20 mA input
is left open or short-circuit the emissivity
setting defaults to 0.95.
