Description
The ZNI1000 is a Ni thin film Resistance Temperature Detector (RTD),
specified to DIN 43760. The high temperature coefficient offers higher
signal outputs than other RTD's, which results in higher accuracy with
smaller temperature changes.
Features
• Resistance at 0°C: 1000
• Nickel temperature detector
• Specified to DIN 43760
• SOT23 package
Applications
• Automotive electronic
• Circuit protection
• Temperature compensation
• Temperature measurement
