Mechanical and Material Data
- Probe tip uses PPS polyphenylene sulfide for high thermal stability
- Probe case uses AISI 304 stainless steel for corrosion resistance
- Thread type equals 5/8-18 UNF
- Maximum thread engagement length equals 0.938 inch
- Minimum bend radius equals 25.4 mm
- Design supports repeated installation without case deformation
- Viton O-ring creates pressure seal between tip and case
Electrical and Cable Parameters
- Cable impedance equals 75 ohm triaxial structure
- Cable insulation uses FEP for chemical and heat resistance
- Total probe length equals 9 meters
- DC resistance at 9 m equals 8.5 ± 1.1 ohms
- Low noise cable supports stable signal transmission
- Triaxial design improves EMI and RFI rejection
- Connector type uses miniature coaxial ClickLoc system
Temperature and Pressure Limits
- Operating and storage temperature range equals −52°C to +177°C
- Short exposure below −34°C may reduce pressure seal life
- Probe seals differential pressure between tip and housing
- Factory does not pressure test each probe before shipment
- Users can request custom pressure seal verification
Torque and Mounting Limits
- Maximum case torque equals 45.2 N·m
- Recommended case torque equals 15.2 N·m
- Connector torque recommendation equals finger tight
- Maximum connector torque equals 0.565 N·m
- Correct torque protects thread and signal stability
Temperature Classification Guide
- T1 class supports ambient up to +232°C
- T2 class supports ambient up to +177°C
- T3 class supports ambient up to +120°C
- T4 class supports ambient up to +80°C
- T5 class supports ambient up to +40°C
- Dc classes define surface limits from T280°C to T90°C
Performance Selling Points
- High temperature probe design suits turbine and compressor systems
- Stable impedance supports long cable runs without signal loss
- Compact 2.5 inch case fits tight machine locations
- ClickLoc connector speeds up field replacement work
- Stainless body resists oil, mist, and process chemicals
Standard Packing and Delivery
- One proximity probe assembly
- Protective cap and thread cover
- Factory label and trace code
- Outer shock resistant packaging
- Courier options include FedEx, UPS, and DHL
Professional FAQ and Selection Help
- How do I choose the correct probe length
Measure the routing path and add service loop before you select cable length - What thread type must match the machine port
Check the mounting hole and confirm it uses 5/8-18 UNF thread - When should I avoid very low temperature exposure
Avoid long exposure below −34°C to protect the pressure seal ring - Does cable type affect signal quality
Yes triaxial cable reduces noise and improves measurement stability - What connector style helps fast maintenance
ClickLoc connectors allow quick change without special tools
