Industry Applications for Reliable Protection
The PPS tip withstands harsh conditions, while the stainless steel case resists corrosion. By integrating this probe into your condition monitoring system, you reduce unplanned downtime and extend equipment life.
Installation and Setup Guidance
Mount the probe using the M10 x 1 thread with a maximum thread engagement of 15 mm. Ensure the target surface is clean and within the linear range (0.25 to 2.3 mm). For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. Keep field wiring length between the probe and monitor under 305 meters (1,000 feet) to avoid signal roll-off at high frequencies. Set the initial gap to -9 Vdc for radial vibration monitoring.
Maintenance and Reliability
Inspect the probe cable and connector periodically for wear or damage. Avoid exposing the probe to temperatures below -34°C (-30°F), as this may cause premature failure of the pressure seal. The probe is designed to seal differential pressure between tip and case using a Viton® O-ring. For applications requiring pressure testing, contact the custom design department.
Compatibility and Integration
The 330103-00-12-10-12-00 works with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga requirements. For non-incendive circuits per drawing 140979, it supports Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc. Always verify your system compatibility before ordering.
