Typical Accessories (0m system, no extension cable)

Probe: 330191-00-26-00-00 (comes with 0m cable, direct connection)

Preamplifier: 330180-X2-00

Monitoring Module: 3500/40 (Axial Vibration), 3500/42 (Axial Displacement) Application scenario

The installation point of the probe is very close to the cabinet (within 1m), and no extension cables are required.

Short-distance vibration/ displacement monitoring in the high-temperature area of gas / steam turbines

Monitoring of high-temperature equipment with limited space and the requirement for simple wiring

Installation points

A complete 50Ω matching must be used: 75Ω/300Ω systems must not be mixed

The probe is directly connected to the preamplifier, and no extension cables can be added (the model is defined as 0m)

The recommended gap is 1.27mm (50mil)

The cables must not be cut or severely bent; keep away from power / frequency conversion cables

The shield layer should be grounded at one end on the control cabinet side
