1. Introduction

1.1 General

In the IR-FA series fiber optic radiation thermometers, four kinds of models, single color type Models

IR-FAI and IR-FAS and two-color type model IR-FAQ and IR-FAQI, and IR-FAQH, and IR-FAQS are

available.

The thermometer, the fiber optics, and the lens assembly are connected through optical connectors. The

radiation energy collected through the lens is transmitted to the element through the optical fiber and is

converted into an electrical signal. The element output is digitally converted and processed through

emissivity compensation, linearizer, and modulation. The standardized final output is 4 to 20mA DC.

Functional keys make programming or selection of emissivity, signal modulation and alarm function easy.

Two types of the lens assembly are available, a universal type, and the lens assembly with a viewfinder.

An air purge case is available for the universal type lens assembly.
