Heraeus High Accuracy Thin Film Element Class A PT100 For RTD Sensor
Produktbeskrivning
Thin film platinum thermal resistance chip is a product of the development of epoch-making temperature sensor. Using the most advanced high-tech methods, such as laser spray plating, microphotography and printing lithography. The resistance value is fine-tuning in the digital trimming way, thus providing the most accurate resistance
Technical description
● Product performance meets the standards of IEC751-1995 and JIS1604,●Temperature coefficient R100/R0=1.3851.● After strictly picking up and indicating the exact value of each element at 0 centigrade.● Film Pt thermal resistance element with ceramic and platinum specially made to maintain excellent stability under high temperature, suitable for use in the -70 C ~ 6OO temperature.The platinum film is spatter on the surface of the ceramic by laser, thus the thin film platinum thermistor element has good anti vibration and anti shock properties.● The surface of the film is covered with ceramics, so the element can withstand high voltage and has good insulation.
Funktioner:
1.with quick thermal response, reducing dynamic error.2.small diameter, no limit on length.3.high measuring accuracy4.imported film resistor with high reliability and stability
