Precision Digital Corporation

Established in 1974, Precision Digital Corporation designs, develops, manufactures, sells and distributes digital panel meter devices driven by embedded systems that transform, display and control critical process information. Our products can be located virtually anywhere in the plant; from the control room to Class I Div 1 areas (both explosion-proof and intrinsically safe). They will accept virtually any analog signal such as 4-20 mA, thermocouple, RTD, DC voltage and pulse as well as digital serial data, such as Modbus. Products include Digital Panel Meters, PID Process and Temperature Controllers, Annunciators, Multi-Channel Controllers, Loop-powered Indicators, Flow Rate Meters and Totalizers, Batch Controllers and Pump Controllers.

Application: Acid Tank Level Monitoring in Feet & Inches

Batch Control in Hazardous AreaThese two PD6801 ProtEX-F&I Feet and Inches level meters are being used to display tank level safely at ground level. Previously, an operator needed to climb to the top of the acid solution storage tanks; just to read the level. This was a dangerous and time consuming solution.

Each PD6801 Feet and Inches level meter reads the 4-20 mA signal from a radar level transmitter at the top of a tank. The LCD display is ideal for reading in sunlight, and the rugged explosion-proof enclosure is great for this tough environment. Now they have a easy to read feet and inches display solution that includes a bar graph tank level indicator, and no dangerous tank climbing is required.
