Description

PT100 Temperature Sensor Platinum Resistance PT1000 Temperature range - 70~500 degrees A B 2B class pt100 platinum resistance

Performance and parameters

1. Temperature coefficient TCR of platinum resistance element
TCR=R100-R0/ R0×100
among them
R100Resistance at 100°C
R0Resistance at 0°C
We provide platinum resistance components with TCR=0.003851 in accordance with IEC751. In addition, we can also provide customers with other temperature coefficient platinum resistance components such as TCR=0.003750.

4.Stability of platinum resistance elements
Platinum resistance elements have good long-term stability. For example, the CRZ-1632 lasts for 300 hours at 400°C. The maximum temperature drift at 0°C is only 0.02°C.
5.Thermal response time of platinum resistance elements

6.Self-heating and test current of platinum resistance elements
The test current of the platinum resistance element should not exceed the allowable value. For example, the CRZ-1632 element is installed in a φ8mm protection tube without any filler, and is immersed in the stirring water at 0°C. When the test current is 1mA, the self-heating temperature rises to 0.05°C. When the test current is 5mA, the self-heating temperature rises to 2.2°C.
