Professional FAQ
When would I need a 250mm long probe case?
When mounting through a thick housing or casing. The long length allows the probe to pass through insulation, brackets, or deep mounting bosses to reach the measurement point.
How does the 5-meter cable affect system setup?
It often connects directly to the monitor junction box. This removes one connection point (probe to extension cable), improving reliability and saving installation time.
What is the torque specification for M8x1 threads?
For M8 threads, use 5.1 N•m (45 in•lb) as the target. Never exceed 7.3 N•m (65 in•lb). Over-torquing can strip threads or damage the probe tip.
Can this armored probe be used in high-pressure applications?
The probe has a Viton® O-ring seal for differential pressure. However, it is not pressure-tested before shipping. For critical pressure applications, contact Bently Nevada’s custom department for testing.
What is a key installation tip for long, fully-threaded probes?
Use a thread guide or starting nut. The long, thin threaded body can bend or cross-thread easily. Start the first few threads by hand very carefully to ensure perfect alignment before using a tool.
