Scanned Area at Various Distances Chart A foto-captor remote version foto-captors are available with different temperature ranges, viewing angles and electrical outputs. They are supplied with and without fiber optics, integral or remote lens systems. The "Type Code" is used to identify the part number of your desired unit. Temperature Response Curve Chart B Type code foto-captor temperature range Chart B illustrates the increase in set-point temperature, required to operate the foto-captor, relative to the percentage of the scanned area containing the hot product. Example: foto-captor type 1301.-response temperature, when scanned area is covered 100% by hot product = 450 °C However, if only 5% of scanned area contains hot product, the foto-captor requires an additional (from chart above): 250 °C Effective response temperature is therefore:

foto-captorremote version • Interchangeable Lens and Fiber Optic Cable (FOC) • IR Test Circuit • Optical Test of FOC • Simple to install • Remote mounting of electronics Design Features The use of fiber optic cables enables mounting of the electronic unit at a distance from the high temperature area. This has the advantage of allowing detection of IRradiation of hot material from close range. The following design variations are available for such cases. Infrared Test Function The IR test function activates a built in IR beam, thus testing the foto-captor function. This test is of special advantage where...
