New PhoenixTM MiniMag Magnetic Thermocouple …… you don ’ t always need to be big to be powerful !
PhoenixTM ( Phoenix Temperature Measurement ) has launched a new MiniMag thermocouple to complement its extensive thermocouple range . The thermocouple is a critical component of the thruprocess temperature profile system offered for product temperature monitoring of paint and powder coating applications . A perfect addition to the new PhoenixTM PTM1500 Epsilon-x ATEX approved paint monitoring system . The thermocouple design is ideal for automotive steel car body shell monitoring through continuous paint cure ovens . As its name suggests , the compact size allows easy quick placement in the tightest of product recesses on any production or test body . The sensor head is only 30 mm diameter and 15 mm high so the MiniMag will fit in places previously impossible using traditional magnetic thermocouple designs .
The design allows for use even in areas where the surface may not be flat . The strong samarium cobalt magnet allows quick reliable strong fixing ( Max Energy Product 32 MGOe ) to any steel surface and is almost totally unaffected by temperature even at 200 ° C / 400 ° F . The Samarium Cobalt ( Sm2Co17 ) magnet has a magnet temperature coefficient of only -0.03 % per degree ° C . This means only 7 % loss in magnetic strength even when operating at 250 ° C . Other magnet types can suffer from significant loss of magnetic power with increasing temperature . With a sprung-loaded hot junction , sensor contact with the substrate is guaranteed ensuring a high accuracy of measurement . The magnet is encapsulated within the sensor housing , so no direct contact is made with either metal or surface coating . This eliminates any damage or loss of magnet post run if sensor removal is difficult due to coating adhesion ( eg Ecoat process ). Provided with an ergonomic shaped housing the MiniMag is easy to handle even with a gloved hand for quick safe placement and retrieval . Being constructed of Aluminium the sensor head is light weight and minimizes thermal mass effects . An innovative unique design feature of the MiniMag thermocouple permits replacement of cable and sensor , significantly reducing consumable costs . The thermocouple is compatible with most competitive profiling systems which means that even users of competitive systems can benefit from reduced consumable costs . Replacing a complete thermocouple due to damage to the cable is both frustrating and wasteful . This feature offered with other Phoenix thermocouples also allows
customization of the thermocouple with different cable lengths allowing the thermocouple to be adapted to suit the size and form of body shell being monitored .
All PhoenixTM thermocouples are manufactured to the highest quality standards and conform to ANSI MC96.1 ‘ Special Limits ’ specification ( type K ). The thermocouple construction is designed to withstand handling in an industrial setting . The PTFE insulated cables are triple wrapped with a stainless-steel braid to give robust operation up to 265 ° C . Whatever your application , PhoenixTM can offer you a thermocouple solution to suit from its comprehensive range , including clamp , offset magnetic , automotive aluminium clamp , washer , and exposed junction designs .
