Temperature Meters & Sensors Temperature NR Series Sheathed Resistance Thermometers     The NR series sheathed resistance thermometers are the high performance resistance thermometers with high sensitivity, solidity, and durability required in a general industrial sensor. The thermometer is constructed by densely filling the gap between a protective tube and a resistance thermometer element with magnesium oxide. The thermometer has excellent response. vibration resistance and impact resistance, and withstand long-term continuous operation in hot and unfavorable environment.   Features Quick response Excellent heat resistance and corrosion resistance Excellent vibration resistance and impact resistance Easy-to-use terminal head Specifications Element Pt100, JPt100, 3-wire type Class JIS A, B Measuring current 2mA, 1mA Measuring temperature -200 to 500°C Protective tube material SUS316 Protective tube outer diameter 3.2mm, 4.8mm, 6.4mm, 8.0mm Protective tube length 300 to 2000mm Top shape Closed type Bending radius More than 2 to 3 times of protective tube outer diameter (R 2D to 3D) Disable bending part 100mm from top Mounting metal Impossible to mount metal within 70mm from top Insulation material High purity magnesium oxide (MgO) 2-element type protective tube diameter (Element diameter) 3.2mm, 4.8mm, 6.4mm, 8.0mm Response time (From 0°C to 100°C boiling water) Protective tube outer diameters Response 63.2% 90% 3.2 mm 2.0 seconds 4.6 seconds 4.8 mm 3.0 seconds 7.0 seconds 6.4 mm 6.8 seconds 15.7 seconds 8.0 mm 7.2 seconds 17.9 seconds Page Top   BACK
