surement systems. They are energy transducers designed to measure accurately and
repeatedly the amount of heat energy emitted from an object and to convert that ener-
gy into a measurable electrical signal.
Each model operates as an integrated temperature measurement subsystem consist-
ing of optical elements, spectral filters, integrated detector, digital electronics and a
NEMA-4 (IEC 529, IP 65) housing. They are built to operate on a 100 percent duty
cycle in industrial environments. Outputs consist of standardized thermocouple or
current signals commonly available for use with controllers, recorders, alarms or A/D
interfaces.
Note: When reviewing this manual, inquire of possible exceptions resulting from customized
features. Check with your sales representative whenever a parameter is critical or oper-
ation seems abnormal.
