Industry Applications
In oil and gas refineries, the 107770-02-02 monitors critical rotating machinery such as compressors and pumps in hazardous zones. Similarly, chemical processing plants use this housing to measure vibration on agitators and blowers where explosion-proof ratings are mandatory. The CENELEC approval ensures safe operation in Group IIC atmospheres, making it ideal for hydrogen, acetylene, and other highly flammable gas environments.
Installation & Setup Guidance
Mount the 107770-02-02 using the 3/4-14 NPT threaded connection. Ensure the mounting surface is clean and flat. Connect the cable via the 1/2-14 NPT explosion-proof fitting, using approved conduit or cable glands. Verify that all connections meet local hazardous area standards. The preassembled design reduces field assembly errors and speeds up installation. Always ground the housing per manufacturer specifications.
Maintenance & Reliability
Routine inspection of the transducer housing involves checking for physical damage, corrosion, and secure mounting. The robust construction of the 107770-02-02 minimizes maintenance needs. In hazardous areas, ensure the cable entries remain sealed. The factory assembly of the Velomitor sensor and housing enhances long-term reliability, reducing the risk of false readings due to improper installation.
