Platinum Resistance Temperature Detector MN 222 MN- series PRTDs are designed for large volume applications where long term stability, interchangeability and accuracy over a large temperature range are vital. Typical applications are Automotive, White Goods, HVAC, Energy management, Medical and Industrial equipment.

Specification DIN EN 60751 (according to IEC 751) Temperature range Tolerance Class A: Tolerance Class B: Tolerance Class 2B: -50°C to +300°C -70°C to +500°C -70°C to +500°C (temporary use at Cl. B and 2B to 550°C possibl e) Temperature coefficient TCR = 3850 ppm/K Leads Ni- wire Recommend connection technology: Welding and Brazing Lead lengths (L) 10mm ±1mm Ambient conditions Unhoused for dry environments only Insulation resistance > 100 MΩ at 20°C; > 2 M Ω at 500°C Self heating 0.4 K/mW at 0°C Response time water current (v= 0.4m/s): air stream (v= 2m/s): t0.5 = 0.05s t0.9 = 0.15s t0.5 = 3.0s t0.9 = 10.0s Measuring current 100Ω:0.3 to 1.0mA 500Ω:0.1 to 0.7mA 1000Ω:0.1 bis 0.3mA (self heating has to be considered) Application advice 1. To avoid shear forces on the connection area, the connection wires may be neither split or bent. The bending may only take place 3 mm after the element, using a bending or splitting tool. 2. Other nominal values, lengths and temperature coefficients on request. 3. Due to a production-caused oxide layer coating the leads, soft-soldering is restricted. Note Other tolerances, values of resistance are available on request. We reserve the right to make alterations and technical data printed.
