Expert Insight & Application

The 330881-28-06-155-03-02 is specifically valued for its 155 mm penetration, making it ideal for large steam turbines or pumps with thick insulation. The glass-reinforced PPS housing provides excellent UV and chemical resistance, while the integrated Proximitor sensor reduces the need for external junction boxes. It is best suited for measuring shaft vibration and axial position on machinery with shaft diameters of at least 50.8 mm.

Professional FAQ & Selection Guide

• Can this unit be used in extremely cold environments?
• The probe is rated down to -51 °C, but ensure the housing is not exposed to temperatures below –34 °C for long periods to protect the pressure seals.
• Does the housing provide electrical grounding?
• Yes, the unit includes an AISI 304 Stainless Steel grounding liner and retaining plate for signal integrity.
• What happens if the input voltage is more positive than -23.5 Vdc?
• Operation at voltages more positive than -23.5 Vdc when using barriers can result in a reduced linear measurement range.
• Is the probe cable replaceable?
• The 1-meter triaxial cable is integrated into the probe assembly. If damaged, the probe and sleeve assembly typically require full replacement.
• Selection Guide:
• Always verify your “B” (Standoff) and “C” (Penetration) dimensions before ordering. The 330881-28-06-155-03-02 requires a 3/4-14 NPT port for secure mounting.
