MAGIC II

TEMCO Engineering is proud to introduce the Magic II, a Smart upgrade for your existing DeZurik® meter for faster response and improved reliability.
  • Pre-calibrated for ten different types of stock to match any furnish.
  • Improved dampener for fast consistency response.
  • Improved gear box seals means leak free performance.
  • Non-contact torque measurement means no drift or damage to electronics from impacts to shaft or disk.
  • Predictable consistency. Minimal deviation to species changes. Ideal for secondary fiber.
  • Mounts on existing chambers. No pipeline changes are necessary.
  • HART compatible meter can be recalibrated from control room.
  • Loop Powered.

The Magic technology is more responsive to rapid changes in consistency. This enables the controller to "see" process upsets and hold consistency closer to set point. By reducing consistency variations in the feed stock to the Paper Machine, paper quality will be improved while using less fiber.

TEMCO Engineering's Magic II is a loop powered upgrade for your existing rotary DeZurik® consistency transmitter. The transmitter measures consistency by sensing the change in viscosity with a disk rotating in the paper stock. A non-contact electronic system eliminates accuracy problems caused by friction, and drifting problems caused by wear and corrosion.

Magic II's SMART feature has ten response curves stored in memory to match the nonlinear pulp response curves. This gives higher accuracy than traditional linear response curves because it adjusts for higher sensitivity at low consistency and lower sensitivity at higher consistency.

Magic II's HART features uses digitally set upper and lower range values. With a HART compatible device, you can program or read the loop's current output and consistency value anywhere the 4ma to 20ma wires run; from the control room to the transmitter.

HOW DOES Magic II  WORK?

Magic II measures consistency by sensing changes in torque, and converting it into a 4ma to 20ma reading like any other DeZurik® rotary consistency transmitter. The degree of torque applied to the rotary disk affects the distance (air gap) between the torque arm and the ThermaCoil. A change in distance between the torque arm and the ThermaCoil changes the inductance. This change in inductance affects the frequency of the oscillator circuit which affects the amount of voltage drop across a coil / capacitance circuit. A two wire transmitter chip with HART protocol converts this voltage change to a 4ma to 20ma current signal which is independent of load or supply voltage.

A silicone oil damper removes most of the normal consistency noise. A digital filter is built in for additional damping if necessary. A thermistor is used for temperature compensation.
