Application Notes
●
●
●
●
●
Using the sensor beyond the Maximum Permissible Power may generate excessive heat and deteriorate the
performance and characteristics of the sensor.
The rated Resistance Values are measured using specific testing circuits. Characteristics of the sensor vary
when using other testing circuits in different conditions.
Do not use the sensor beyond the Operating Temperature Range.
Do not touch the terminal area when screwing the sensor. Impressing a strong force upon screws can damage
the sensor and deteriorates its performance.
Dropping or impressing a strong force may damage the sensor. Do not use the sensor if once dropped.
Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
Should a safety concern arise regarding this product, please be sure to contact us immediately.
