NB-PTCO-142
Overview
The NB-PTCO-142 is a high-precision PT100 Platinum Resistance Temperature Detector (RTD) manufactured by TE Connectivity. It offers a wide operating temperature range from -30 degrees Celsius up to 300 degrees Celsius with a standard temperature coefficient of 3850ppm/degree Celsius. This sensor is designed for applications requiring high accuracy and long-term stability in a compact PTFM package.
Why Choose This Part
This RTD provides exceptional accuracy of +/-0.15 degrees Celsius (Class A) with a very low resistance tolerance of +/-0.06 percent at 0 degrees Celsius. The platinum construction ensures high linearity across its entire 300 degree Celsius range compared to thermistors. Its small PTFM through-hole form factor allows for easy integration into custom probes or PCB assemblies.
Applications
Key Specifications
Getting Started
To use this sensor, implement a constant current source (typically around 1.4 mA) and a precision instrumentation amplifier or a dedicated RTD-to-digital converter like the MAX31865. Use a 3-wire or 4-wire Kelvin connection configuration to minimize errors introduced by lead wire resistance. Calibration should follow the DIN EN 60751 standard for Pt100 sensors.
