The PRO 50 Single-Wavelength Sensors with Fiber Optics are used to measure most common materials in general purpose applications.  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 and ambient temperature
• 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.

The PRO 52 models feature a unique auto null design that enables more accurate measurements on applications such as cold rolled steel and low temperature induction heating processes where the temperatures can go as low as 100°F (40°C) and the surface has a low or varying emissivity.
