Specifications The PFS Series product range consists of three distinct types of Sensor Cable. Each type has a unique construction that has been designed to accommodate the widest range of installation requirements and environments. All product specifications are subject to change without notice. PFS-504-FR - Type FR Sensor Cable consists of a stainless steel encore tube that contains two independent color-coded quartz fibers each with an outside diameter of .25 mm (.01 inches). The tube cavity is filled with a water-free, heat conducting fill material to ensure that the optical fibers remain waterproof. The outside of the core tube is wrapped with a layer of fine stainless steel wires that improve heat response and add to the mechanical and tensile strength of the cable. The sensor cable is then sheathed with a halogen free, flame retardant HM4 thermoplastic jacket suitable for a wide range of applications and environments. PFS-604-MF - Type MF Sensor Cable is a metal free Sensor and has been specifically designed for use in applications where a high amount of electromagnetic disturbances are expected like tunnels, high voltage cable trays and transformers. To minimize the risk of induced voltages, the construction of the metal free Sensor Cable substitutes a polyamide core tube reinforced with Armed yarn in place of the stainless steel tube and wire used in the FR type Sensor. The outer jacket consists of the same halogen free, flame retardant HM4 thermoplastic used throughout the product line. This series is best described as multi purpose, and is well suited to a wide range of both commercial and industrial applications. PFS-348-EX - Type EX Sensor Cable is specifically designed for use with the OTS Controllers containing Option D, EX-Zone Access. This system combination has been classified in accordance with ATEX Group II, Category 1G, "Increased Safety." The Sensor consists of a stainless steel core tube that contains four quartz glass fibers. Two of the fibers are available for temperature monitoring and two are intended to be used in a supervisory mode to shut down the OTS laser should the sensor cable become damaged or broken. Like all PFS Series Sensors, the core tube is filled with a hydrophobic gel to protect the fibers from water entry. The outside of the core tube is wrapped with a layer of aluminum wire that improves both the heat response, and the mechanical deflection characteristics of the cable. The sensor cable is jacketed with a halogen reed, flame retardant HM4 thermoplastic material to a final diameter of 8 mm (.32 inches). | |
