Professional FAQ

• What is the primary benefit of the -175 penetration depth?
• It allows the probe to reach the shaft target through heavy insulation or thick turbine casings.
• Can I use this module in an explosion-proof zone?
• No, the 330881-16-00-175-00-02 does not have hazardous area approvals.
• What type of field wiring is recommended?
• We suggest using 3-conductor shielded triax cable for optimal signal integrity.
• Is the housing resistant to outdoor UV exposure?
• Yes, the PPS material is UV-stabilized and verified for outdoor industrial use.
• What happens if the supply voltage is more positive than -17.5 Vdc?
• The unit may fail to operate or show a significantly reduced linear measurement range.
