Fluid Level Control in a Forming Tank
To control the fluid level in a forming tank in a washdown environment
To create a ceramic form, a vacuum is applied to a ceramic fiber suspended in an aqueous solution. Float mechanisms are ineffective for level control because the fiber adheres to the float, rendering it inoperable.
Instead, a T30 UHPA ultrasonic sensor with pump in/pump out logic is used, with the power supply and 24 volt DC relay housed in a NEMA 12 enclosure behind the production line. The sensor is impervious to the washdown procedure conducted at the end of each shift.
