Frequently Asked Questions (FAQ)
System Configuration
What do the “B” and “C” dimensions mean?
“B” (40mm) is the standoff. “C” (132mm) is how far the probe sticks into the machine. These set the measurement point.
Is the transducer cable included?
Yes. A 1-meter triaxial cable connects the internal probe to your junction box. You need longer field wiring to the monitor.
Performance & Installation
What is the benefit of “vibration isolation”?
The silicone mounts reduce shaking from the housing. This gives a cleaner vibration signal from the machine shaft.
What voltage should I supply?
Use -24 VDC standard. If using safety barriers, ensure the supply is between -23 VDC and -26 VDC.
Purchasing Guidance
Why choose PROXPAC XL over separate parts?
It saves time. The probe is already aligned and sealed in the housing. You install one complete unit, not multiple pieces.
