The enclosed Roto-Tran IV is a pressure transducer that provides a 4-20 mA signal over its labeled pressure range. The Roto-Tran IV comes in six different pressure choices that cover the pressure range from 0 - 300 PSI. This loop powered, temperature compensated device uses a piezo-electric sensing element.

The unit is constructed from 316L stainless steel and carries a NEMA 4X rating. Tank and pipe mounting can be accomplished by its integral, threaded pressure connection.

ENCLOSED

A NEMA 4X non-metallic enclosure houses the Roto-Tran IV pressure transducer, block and bleed valve and pressure gauge.

A terminal strip for field wiring is included. The pressure line connection to the block and bleed assembly is through a 1/4" female NPT bulkhead fitting located on the bottom of the enclosure
