FluidLoc Cable Option
The -12 option specifies FluidLoc cable with a connector protector. The FluidLoc option prevents oil and other liquids from leaking out of the machine through the cable's interior. Therefore, it is highly recommended for turbine and compressor applications where oil exposure is possible.
Connector Protector Option
The 330730-080-12-00 also includes the connector protector option. This provides additional protection of the connectors in a humid or moist environment. Connector protectors are recommended for all installations and provide increased environmental protection.
Note: Silicone tape is also provided with each 3300 XL extension cable. It can be used instead of connector protectors. However, silicone tape is not recommended in applications where the probe-to-extension cable connection will be exposed to turbine oil.
Connector Features
All components of the transducer system have gold-plated brass ClickLoc connectors. These connectors lock into place, preventing the connection from becoming loose. The patented TipLoc molding method provides a robust bond between the probe tip and the probe body. In addition, the probe cable is securely attached to the probe tip utilizing the patented CableLoc design. Consequently, it provides 330 N (75 lb) pull strength.
Temperature Range
The 330730-080-12-00 handles extreme temperatures effectively.
Operating and Storage Temperature: -52°C to +177°C (-62°F to +351°F).
Linear Range and Gap Setting
The 3300 XL 11 mm proximity system provides an extended linear range.
Linear Range: 4.0 mm (160 mils).
Linear Range Begins: Approximately 0.5 mm (20 mils) from target.
Linear Range Extends: 0.5 to 4.5 mm (20 to 180 mils) (approximately -1 to -17 Vdc).
Extended DSL Range: 0.5 to 5.0 mm (20 to 200 mils) (-1 to -19 Vdc).
Important Note: The extended DSL range is not applicable when using zener barriers.
Recommended Gap Setting: 2.5 mm (100 mils).
Field Wiring Guidelines
Field wiring connects the Proximitor Sensor to the monitor.
Wire Size: 0.2 to 1.5 mm² (16 to 24 AWG).
With Ferrules: 0.25 to 0.75 mm² (18 to 23 AWG).
Recommendation: Use three-conductor shielded triad cable.
Maximum Length: 305 meters (1,000 feet) between Proximitor Sensor and monitor.
Note: See the frequency response graph for signal rolloff at high frequencies when using longer field wiring lengths.
Mechanical Specifications
The 330730-080-12-00 uses high-quality materials.
Probe Tip Material: Polyphenylene sulfide (PPS).
Probe Case Material: AISI 304 stainless steel (SST).
Probe Cable Specification: 75 Ω triaxial, fluoroethylene propylene (FEP) insulated.
Probe Lengths Available: 1, 5, or 9 meters.
Locknut Feature
The 3300 XL 11 mm probe comes standard with a locknut with pre-drilled safety wire holes. Therefore, safety wire can be installed to prevent loosening under vibration.
Calibration Note
Proximitor Sensors are supplied by default from the factory calibrated to AISI 4140 steel. Calibration to other target materials is available upon request.
Key Features
The 330730-080-12-00 offers several advantages for proximity measurement.
FluidLoc Cable Design:
Prevents oil and other liquids from leaking through the cable interior. Therefore, it is essential for turbine and compressor applications.
Connector Protector Included:
Provides additional protection in humid or moist environments. Connector protectors are recommended for all installations.
Gold-Plated ClickLoc Connectors:
Lock into place to prevent loosening. Thus, this ensures reliable connections under vibration.
High Pull Strength:
The CableLoc design provides 330 N (75 lb) pull strength. Consequently, the cable remains securely attached to the probe tip.
Wide Temperature Range:
Operates from -52°C to +177°C. Hence, it suits extreme climate conditions.
No Agency Approvals:
The -00 suffix indicates no hazardous area approvals. Therefore, this cable is for non-hazardous (safe area) installations only.
Typical Applications
The 330730-080-12-00 suits various turbomachinery monitoring applications.
Connecting 3300 XL 11 mm probes to Proximitor Sensors with FluidLoc requirement.
Installations where oil leakage through the cable interior must be prevented.
Applications with high humidity or moisture exposure requiring connector protection.
Turbine and compressor monitoring where FluidLoc is specified.
Retrofit of existing 3300 XL systems with FluidLoc cables.
Installation Guidelines
Install the 330730-080-12-00 between the 3300 XL 11 mm probe and the Proximitor Sensor. First, connect the gold-plated ClickLoc connectors by pushing them together until they lock. Then, verify the lock is secure.
The FluidLoc cable prevents oil leakage. Route the cable away from sharp edges and excessive heat sources. In addition, use the connector protector to seal the connection in humid environments.
Furthermore, observe the minimum bend radius for the cable. Do not exceed the maximum field wiring length of 305 meters between the Proximitor Sensor and monitor. The locknut with pre-drilled safety wire holes can be safety wired for vibration resistance. Since this model has no hazardous area approvals, install it only in safe (non-classified) locations.
