Measuring and controlling the temperature profile in the older rotary kilns is desirable for optimised operation. In addition to de-multiplexing the temperature signal from the kiln, the Rotary Kiln De-Multiplexer has several internal registers which are accessible via the serial interface providing a range of alternate functions which are generally not used. One such function is the time in seconds per kiln revolution.
Rotary kiln de-multiplexer
An existing product, the Programmable Signal Transmitter, was modified to access this kiln rotation time using RS485 to produce an analogue output proportional to kiln speed. Typical rotation times are from 60 to 300 seconds - that is around 0,2 to 1 rpm. The new product, called the Rotary Kiln Speed Transmitter, produces a 4 to 20 mA output proportional to kiln speed. At 0,2 rpm (300 seconds per revolution) the output is 4 mA and at 1 rpm (300 seconds) the output is 20 mA.
The Rotary Kiln Speed Transmitter is programmable so that the output range can be set up for any kiln speed. There are high and low speed alarms as well as a communications alarm. LEDs indicate the state of the communications and the speed alarms with relay outputs which can be used to signal faults to other systems or annunciators.
