Description
ZNI1000 Temperature sensor
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
