Description
The Optek Control C4000-EX photometric converter is designed for demanding industrial applications, converting signals from uv, visible (vis), and near-infrared (nir) sensors into accurate, real-time measurements. It supports absorption-based and scattered light-based sensors, enabling operators to monitor absorbance, transmittance, and concentration in various units such as cu, od, %-tr, ppm (de), ebc, ftu, g/l, and more.

Equipped with a graphic lcd display (240 × 128 pixels) and led backlight, the C4000-EX can show one to four configurable values simultaneously, including numeric data, bar graphs, and trendlines. It also features factory zero for scattered light sensors, a secondary user zero, and slope/shift adjustments to compensate for long-term process disturbances.

The module offers flexible software tools, including 8 parameter sets, 16 linearization tables (max 11 points), 8 offset and slope sets, auto zero (local or remote), and password protection at three levels. It provides galvanically isolated 0/4–20 ma outputs, remote control of parameter sets, zero, and hold functions, and optional ex-proof versions conforming to fm and atex standards.

With selectable 115/230 v ac or 24 v ac/dc power, low consumption (<50 va), and durable housing options (stainless steel, polyester, silicone, glass, and diverse plastics), the Optek Control C4000-EX combines precision measurement, robust design, and flexible integration for critical industrial photometric applications.
