Frequently Asked Questions
Why must the connector end of the 148239 probe remain un-submerged?
While the probe body and Tefzel tubing seal the sensor tip against fluids, the miniature coaxial ClickLoc connector at the cable end is not liquid-tight and must reside in a dry junction box.
Can this 304 stainless steel probe be deployed in marine salt-water environments?
No, the 304 stainless steel case is not rated for salt-water applications; deployment should be restricted to fresh-water or compatible closed-loop industrial process fluids.
What is Global PLC Spare HUB's Insight on protecting Tefzel tubing during routing?
Global PLC Spare HUB recommends avoiding sharp pinch points and tight radius bends along the Tefzel tubing to prevent internal micro-fractures in high-flow fluid environments.
How does pressure rating verification work for high-pressure fluid applications?
Standard probes are pressure-rated to 34 Bar, but custom factory pressure testing should be requested if your operating differential pressure exceeds this baseline threshold.
What precautions are necessary when installing 11mm probes in hazardous explosive zones?
Ensure the system is installed using approved intrinsically safe zener barriers (drawing 141092) or galvanic isolators to maintain Zone 0 and Zone 2 compliance ratings.
