The PRO 200 Multi-Wavelength Sensors with Fiber Optics are used with applications involving non-greybody materials such  as aluminum, brass, copper, stainless steel, and zinc.  With the fiber optic configuration, it is possible to view a target and mount the sensor electronics in a remote or more convenient location.  This provides greater durability and flexibility with sensor installations that involve confined spaces and/or severe environments. 

Standard Features:

• A wide selection of temperature ranges and optics
• Fiber optic alignment with a small, sealed fiber cable
• Optional Integrated Aim Light to verify alignment
• An intuitive text based user interface
• Programmable outputs and alarms for measured target temperature, signal strength (emissivity), signal dilution, and ambient temperature
• Up to Four menu-selectable, application specific ESP Algorithms
• Advanced ESP Filters for Signal Strength and Signal Dilution
• Bi-directional RS485 and RS232 communications
• Advanced system diagnostics and status messages
• Rugged, corrosion resistant NEMA 4 / IP65 enclosures
• Stand alone and system configurations
• A wide selection of accessories

Unique Features:

All of Williamson’s fiber optic sensors use a small, sealed fiber optic cable with an ambient limit of 400°F (200°C) to enable access to difficult to reach targets and to survive hostile operating conditions.  In addition, Williamson offers several unique fiber cable options that can enable measurements on applications that were previously considered difficult to measure.  This includes the ArmorGuard System, the Stainless Steel Braid System, and the Gooseneck System.

Multi-wavelength sensors utilize ESP Technology to provide ‘aim and read’ capabilities for materials with complex emissivity characteristics that are not accurately measured by single and dual wavelength sensors.  This includes ESP Algorithms to compensate for complex emissivity characteristics and ESP Filters to filter out bad measurements.  This includes demanding applications involving:

• non-greybody materials such as aluminum, brass, chrome, copper, molybdenum, stainless steel, tin, titanium, tungsten, and zinc
• Intervening Media such as dirty optics, scale, steam, dust, or water spray
• A partially filled field of view caused by a mechanical obstruction, or a small or wandering target
