- Heavy Industrial Machinery: Widely used for vibration and displacement monitoring of large steam turbines, centrifugal compressors, gearboxes, and fans.
- External Installation Requirements: When the internal space or environment of the machine does not allow for direct installation of the probe bracket, this housing can be installed on the outside of the machine casing.
- API 670 Compliance Scenarios: Fully compliant with API 670 standards for external probe installation, commonly used for critical asset protection in the oil, gas, and power industries.
- Online Maintenance Efficiency: By unscrewing the dome cap on the top of the casing, technicians can quickly adjust the probe gap or replace damaged probes, greatly reducing downtime for maintenance.
- Measurement Accuracy: With the 3300 XL 8mm probe, it provides linear measurement accuracy of up to ±1%, with a standard linear range of 2.0 mm (80 mils).
- Mechanical Stability: The combination of a 6061 aluminum alloy body and a 304 stainless steel sleeve ensures both lightweight construction (approximately 1.1kg) and sufficient structural rigidity to reduce parasitic vibration interference.
- Protection Rating: The enclosure is CSA Type 4 certified (equivalent to IP66), providing dust, rain, and corrosion protection.
- Operating Temperature: -51 °C to +177 °C (-60 °F to +351 °F).
- Explosion Protection Rating: CSA certified for Class I, Division 1 & 2, Groups C & D and Class II, Division 1 & 2, Groups E, F & G hazardous environments.
