73- FireTECH Series Thermocouples and accessories The FireTech temperature sensors are designed to measure the temperature of the air or hot surfaces in fire test chambers. The FireTECH system includes: sensors with exposed plate with insulator, surface temperature sensors with disc and a range of accessories such as holding tubes and insulators. All components are made according to EN 1363-1: 2012. Temperature sensors with exposition plate. The measuring element is typically thermocouple type K. The measuring point is located on the plate and protected by an insulator against direct contact with fire. The thermocouple construction is vibration-resistant and the special sheath material provides a long working-life while retaining its measuring properties. There are available straight or bent holding tubes. Specially developed tube and plate connection makes it easy to position the plate in the correct position. Surface thermocouples with disk. Sufrace thermocouples type K are made with a measuring disk in 2 possible variants of the measuring hot-junction. The measuring range, type of hot-junction and electrical connection are agreed individually. All sensors are compliant with PN-EN 1363-1. There is a possibility to make other construction according to special requirements, for example with external Teflon insulation, protecting the inner cable (made of fiberglass insulation) from degradation and damage. technical parameters Measurement element Measuring range Responce time (in air) Thermocouple sheath material Compensating cable Exposure plate Dimension Material Process connection Insulating insert Thermocouple NiCr-Ni / K max+1000 o C - TC diameter 1mm max+1100 o C - TC diameter 1,5mm max+1200 o C - TC diameter 2mm max+1200 o C - TC diameter 3mm t0,9=17s, for TC diameter 1mm, max+1000 o C t0,9=25s, for TC diameter 1,5mm, max+1100 o C t0,9=34s, for TC diameter 2 mm, max+1200 o C t0,9=64s, for TC diameter 3 mm, max+1200 o C Inconel 2.4816 (AB Premium) lub Nicrobel (XL) Silicone cable, ambient temperature -50.. +180 o C Teflon cable, ambient temperature -50.. +250 o C Fiberglass cable, ambient temperature -50.. +400 o C other on request Dimensions and material acc.
