The connector has a protective cover. This shield guards against dust, oil, and physical damage during handling.
Can this probe be used in high-temperature areas?
Yes. It can operate in temperatures up to 177°C (351°F). This suits most industrial environments.
What is the probe's electrical resistance for a 9m cable?
The resistance from the center conductor to the outer conductor is 8.5 ohms, with a tolerance of ± 1.1 ohms.
How should I store this probe before installation?
Keep it in a dry place. Avoid temperatures below -34°C (30°F) to prevent damage to the internal pressure seal.
