Model 564

SKU: 564

Pressure Transmitter, Modular Electronics, Pressurized Vessel Insertion/Removal

The Delta Controls Model 564 is a two wire pressure transmitter designed to measure liquid level and pressure in tanks which cannot be depressurized or allowed to leak. It is suitable for services that are very dirty, leave deposits, and generally tend to plug up any cavity or recess they encounter. The ability to insert the sensor face of the Model 564 all the way into the inside of the vessel usually eliminates these problems. Other applications include process materials that tend to set up or crystallize when stagnant; that solidify and plug sensing lines when allowed to cool, slurries of polymerizing agents, and the like.

The Delta Controls Model 564 can be inserted from the top or side of a vessel as required. Safety stops prevent accidental ejection of the transmitter and rapid discharge of the tank contents into the environment. Block valve, adapters, and pipe fittings may be furnished by the user or by Delta Controls Corp. The sensor is referenced to atmospheric pressure through a vent tube. A desiccant filter or isolation bladder prevents moisture condensation in the vent tube.
