Features:
- 7.5-inch probe penetration provides deep reach for mounting through thick machine casings, insulation layers, or double-walled equipment.
- CSA explosion-proof certification with CSA Type 4 enclosure rating ensures reliable operation in hazardous areas with protection against water and dust ingress.
- Single explosion-proof fitting with plug simplifies installation while maintaining hazardous area integrity for deep mounting applications.
The 21000-28-05-00-075-01-02 is engineered for installations where the probe must reach deep into the machine to encounter the measurement target. Its 7.5-inch probe penetration allows it to pass through thick turbine casings, heavy compressor walls, insulation layers, or double-walled equipment without requiring standoffs or custom adapters.
The 21000-28-05-00-075-01-02 carries CSA explosion-proof certification and is rated as a CSA Type 4 enclosure, providing verified protection against both explosive atmospheres and environmental ingress. This dual certification simplifies compliance for installations in North American hazardous locations while ensuring the housing can withstand washdowns, rain, and dust exposure.
The 21000-28-05-00-075-01-02 is designed with a single 3/4-14 NPT explosion-proof fitting for cable entry and a separate plug for sealing the unused port. This configuration simplifies installation by reducing the number of fittings that must be managed during field wiring, while still providing the flexibility to use either port as needed.

- Energy and Power Generation: Widely used in thermal, hydroelectric, and nuclear power plants for monitoring key steam turbines and generator units.
- Oil and Natural Gas: Suitable for rotating equipment in upstream extraction, midstream transportation (compressurization stations), and downstream refining plants.
- Chemicals and Heavy Industry: Monitors large reactor agitators or high-pressure pumps in highly corrosive, flammable, and explosive chemical processes.
- Standards and Compliance: Specifically designed for industrial facilities that must comply with API 670 (American Petroleum Institute for Mechanical Protection Systems) standards.
- Online Maintenance and Adjustment: When machinery is running (without stopping) but requires recalibrating the probe gap or replacing a damaged probe.
- Space-Confined Internal Monitoring: Bearing housings with extremely limited internal space, making it impossible to directly install internal mounting brackets.
- Precision Measurement in Harsh Environments: Equipment exposed to outdoor, high humidity, or spray environments.
- Explosion-Proof Safety Control Areas: Class I, Div 1, or Zone 0/1 areas with a risk of flammable gas leakage.
- Structural Durability: Utilizing an aluminum body and 304 stainless steel casing, it offers excellent industrial environmental resistance while providing a lightweight design (approximately 1.1 kg).
- No Downtime for Replacement: Designed to allow operators to directly replace probes or adjust clearances from outside the machine, significantly reducing unplanned downtime.
- Sealed Protection: CSA Type 4 rated, dustproof and waterproof, ensuring internal sensor signals are not affected by external contamination.
- Probe Compatibility: Built-in 3300 XL 8mm probe (code -28) provides high-precision analog voltage output.
