Sensortech to trial new Kiln Jam Detector KJD-7000
US: Sensortech Systems is looking for client companies to run extended trials of its new Kiln Jam Detector KJD-7000. Part of the trial will be to test the functionality of the sensor and, over a period of some months, check reliability and stability. Another part is to receive input from users as to what features need to be incorporated, particularly in the software design.
The company says that its new radio frequency (RF) gypsum wallboard jam detector product offers a saving compared to previous sensors. The RF sensor requires no maintenance and is unaffected by siloxane build-up or other debris. The Kiln Jam Detector KJD-7000 uses a custom-designed coaxial cable able to withstand the high operating temperatures.
The sensor itself follows the design of open-frame planar sensors used for moisture measurement. The outer frame is formed from 16ga stainless steel; ceramic insulators isolate a stainless-steel centre electrode to which the high temperature cable is attached. The electronics unit is located outside the dryer at each deck level. An on-board 32-bit ARM-Based micro-controller processes signals from up to three sensors and networks via RS-485 to a dedicated programmable logic controller (PLC).
The system software is set to trigger an alarm when either no product is detected over the sensor for a pre-defined time interval, a blockage upstream, or if a failure to detect gaps between boards over a pre-defined time is recognised. All sensors in an array are node addressable on an RS-485 network. If an anomaly occurs at any sensor, the exact position will be known including which deck and its position on the deck (left, right, centre).
Sensortech will be displaying its new kiln sensor at the Global Gypsum Conference & Exhibition taking place in Krakow, Poland on 25 – 26 October 2017.
Colombia to implement anti-dumping on Mexican gypsum wallboard
Colombia/Mexico: Mexican gypsum wallboard producers including USG Mexico and Abasteco Maxima (Abamax) will have to pay anti-dumping duties on imports to Colombia following an investigation by the Committee on Trade Practices.
