Red Lion Controls, Inc. introduces the PAXDR Dual Rate Meter, providing real-time viewing of dual input rates, paired with sophisticated math functions to measure and display the sum, difference, ratio, draw or percentage of total between the two rates. PAXDR is a 5-digit dual rate indicator and 6-digit dual totalizer that monitors mission-critical factors such as inflow and outflow, unwind and rewind wire tension, feed and tension roll speed, and other pivotal production rates.
Within its industry-standard 1/8 DIN housing, PAXDR simplifies dual rate applications as a single, easy-to-use device—without the need for any complex programming that would otherwise be required to perform application-specific calculations. Six values are viewable on the meter’s .56" LED display: one each for rates A and B, totalizers for A and B, and the rate and totalizer for calculation C. These readings improve production quality and reduce rejects by ensuring a parameter such as feed rate, line speed, flow rate or tension is properly maintained throughout processing.
Users can simply select the desired scale for each of the two signal inputs using PAXDR’s programmable function keys, with independent scaling provided for A and B totalizers. This capability makes PAXDR ideal for applications such as flow measurement, where both flow rate and volume must be monitored and scaled to a common unit of measure. Plus, 10-point scaling for both input rates is provided for challenging non-linear processes.
“Monitoring and comparing two rates at once is often critical in flow, web or extruding applications,” said Jeff Thornton, Red Lion product manager. “If the many points of a continuous process are not kept harmonized, the ramifications can be disastrous.” Thornton adds, “PAXDR eliminates these risks by displaying both individual and total rates for each of the two designated inputs, as well as delivering a rate and totalizer calculation based upon the user’s application parameters—all accessible at the touch of a button.”
To further expand the PAXDR’s capabilities, users may select from several field-installable plug-in option cards, providing features such as:
• Four setpoint outputs, assigned to any rate or totalizer value and configured to suit varying control and alarm requirements
• Retransmitted analog output, scaled independently of the input range
• Communication and bus capabilities, including RS232, RS485, Modbus, DeviceNet™ and Profibus-DP
PAXDR is available with a standard green or sunlight-readable red LED display, with variable intensity for easy readability in conditions ranging from low light to bright sun. Its NEMA 4X/IP65 sealed bezel ensures PAXDR withstands harsh plant floor conditions to deliver dependable, long-lasting operation.
