Transducer Mounting and Gap Voltage Validation
The 21000-16-10-00-090-03-02 housing assembly positions reverse-mount eddy-current probes through casing walls while isolating probe electronics from process fluids and debris. Accurate probe positioning through the 304 stainless steel sleeve allows fine mechanical adjustment to satisfy gap voltage validation targets (-10 VDC baseline) at room temperature. Proper rigid attachment prevents housing resonance under high dynamic machine movement, preserving linear eddy-current probe scaling and preventing phase distortion during rotor dynamics measurement.
Frequently Asked Questions
Q: How is environmental sealing maintained around the internal probe cable entry?
A: The aluminum housing body and terminal seals meet IP66 ingress protection standards, sealing out dust and high-pressure water jets when installed with NPT thread sealant.
Q: Can the internal sleeve length be adjusted in the field?
A: No, the penetration option code specifies a factory-machined sleeve length; field mechanical alterations risk degrading housing structural integrity and environmental sealing ratings.
Field Installation Guidelines
- Inspect the housing threads and O-ring seals for physical damage or contamination before mounting to the machine casing.
- Apply industrial-grade thread sealant to the 3/4-14 NPT mounting threads, ensuring at least 5 full threads of engagement into the tapping boss.
- Thread the reverse-mount proximity probe into the internal sleeve until the probe tip reaches the calculated mechanical offset from the target shaft.
- Connect the probe leads to the extension cable and verify that the output reads nominal -10 VDC gap voltage prior to final sealing.
- Tighten the housing cover to compress the environmental seal and install the 3/4-14 NPT plug on unused conduit ports.

Tech & Buying Guide
Spatial Computing in Industrial Automation: Elevating PLC and DCS Operations with AR and VR
Industry 4.0 integrates digital intelligence into field operations, transforming factory automation landscapes worldwide. Spatial technologies—specifically Augmented Reality (AR) and Virtual Reality (VR)—redefine how engineers interact with industrial control systems. By bridging computer-generated CAD models with real-time operational technology (OT) data, immersive displays enable intuitive monitoring, rapid diagnostics, and safer maintenance across complex processing facilities.
Master Acceptance Testing: Understanding FAT and SAT in Industrial Control Systems
Factory Acceptance Testing (FAT) and Site Acceptance Testing (SAT) serve as critical quality assurance gateways in complex industrial control systems. Both procedures verify that programmable logic controllers (PLCs), distributed control systems (DCS), and associated field devices meet strict functional specifications. However, executing these tests effectively requires clear delineation between off-site staging and final field commissioning.
Industrial Networking Essentials: Demystifying Hubs, Switches, and Routers in Control Systems
Industrial automation relies heavily on robust networking infrastructure to connect programmable logic controllers (PLCs), distributed control systems (DCS), and human-machine interfaces (HMIs). Modern factory automation environments generate vast amounts of real-time operational data across deterministic networks. Understanding the structural differences between hubs, switches, and routers ensures optimal traffic segmentation, minimizes latency, and maintains high network availability.
