YAGEO Nexensos 5220099 Pt1000 RTD
Overview
The 5220099 is a precision Pt1000 platinum resistance temperature detector (RTD) designed for demanding industrial and automotive environments. It features a polymer encapsulated sensor head and long PTFE-insulated wire leads, providing reliable measurement from -50C to 200C with a high temperature coefficient of 3850ppm/degC.
Why Choose This Part
The Pt1000 resistance value reduces the impact of lead-wire resistance compared to Pt100 sensors, making it ideal for the long 250mm leads provided. Its polymer encapsulation and PTFE insulation offer excellent chemical and moisture resistance across the full -50C to 200C range.
Applications
Key Specifications
Getting Started
To use this sensor, implement a constant current source limited to 0.3mA to prevent self-heating errors. The sensor output should be processed through a precision instrumentation amplifier or a high-resolution Delta-Sigma ADC with a ratiometric configuration using a stable reference resistor.
