Description

The 21000-00-00-00-00-02 is a configured proximity probe housing assembly designed for mounting transducers in industrial machinery environments. This specific orderable configuration is supplied without a probe (Option A: 00), without a probe cable (Option B: 00), and without a standoff adapter (Option C: 00), intended for installations where those components are selected or sourced separately. It features two 3/4-14 NPT explosion-proof fittings, one 3/4-14 NPT plug, and one 3/4-14 to 1/2-14 NPT reducer (Option E: 02), suitable for robust conduit termination. This housing assembly protects the transducer from harsh environmental conditions, providing a stable, sealed interface between the machine casing and the monitoring system instrumentation. The unit is constructed with an aluminum body and a 304 stainless steel sleeve to ensure structural integrity and resistance in industrial settings. It complies with API 670 standards for externally mounted proximity probe housings, ensuring compatibility with Bently Nevada transducer systems such as the 3300 XL and 3300 XL NSv series.

Features

Housing Configuration: Aluminum body with 304 stainless steel sleeve for environmental protection and durability.
Fittings (Option E: 02): Includes two 3/4-14 NPT explosion-proof fittings, one 3/4-14 NPT plug, and one 3/4-14 to 1/2-14 NPT reducer.
Mounting: Designed for external mounting on machinery cases to support eddy-current proximity probes.
Standard Compatibility: Meets API 670 standards for externally mounted proximity probe housings.
Construction: Optimized for mechanical protection of transducer leads in hazardous or industrial environments.

Applications

Rotating machinery protection for pumps, turbines, fans, and compressors.
Shaft vibration and axial position measurement installations.
Industrial environments requiring explosion-proof conduit sealing for monitoring instrumentation.
Retrofitting existing machinery with standard 3/4-14 NPT conduit interfaces.

Installation Guidelines

Ensure the housing is securely mounted to the machine case to prevent resonance.
For probe penetration lengths greater than 300 mm (12 in), auxiliary sleeve support is required to prevent vibration-induced failure.
Verify all explosion-proof fittings are properly tightened and sealed to maintain the integrity of the housing assembly.
If installing probes with a penetration length of less than 25 mm (1.0 in), consider using an individual standoff adapter to avoid interference from metal components.
