Product Overview
Kele's P51-300-20-E turns line pressure from 0 to 300 PSI into a 4-20 mA signal for a controller or building automation system. The -E version comes enclosed: the transducer mounts through the wall of a gray junction enclosure, so its 3 foot cable terminates in a box with knockouts for cable glands.

Frequently Asked Questions
What is the process connection?
1/8 inch male NPT, per the carton label.
Is the enclosure part of this number?
Yes. The P51-300-20-E carton reads ENCLOSED, and the transducer comes mounted through the wall of its plastic enclosure.
Why choose the enclosed version over a bare transducer?
The wiring terminates inside a covered box with knockouts for cable glands, so there is a place to make the connection without adding a junction box. Flat-rate shipping in the lower 48, and orders over the free-shipping line ship free.
Three hundred PSI turned into sixteen milliamps of span is the whole job, and it does it without a display to look at. Wire it to your controller and let the trend log do the watching.
