Sensor1. Electrical Characteristics of SA20020501 1-1 Resistance value (at0°C) :20.75±0.10 ohm 1-2 Maximum applied current :1mA 1-3 Insulation resistance :exceed 100M ohm at 500V DC (@ room temp.) 1-4 Self heating :2mW/°C(in air,1m/sec.) 1-4 Operation temperature range :-50°C to 500°C2. Outline Drawings Please see attached figure.3. Reliability Test 3-1 High temperature test keep the Pt sensor in 500°C for 1000 hours. 3-2 Low temperature test keep the Pt sensor in -50°C for 1000 hours. 3-3 Humidity test keep the Pt sensor in 60°C and 90 to 95% RH for 1000 hours. 3-4 Thermal shock test keep the Pt sensor in 0°C ice water for at least 15 sec., then within 10 sec. directly put into 100°C hot water for at least 15 sec.. The above process should be proceeded for at least 10 cycles.
