A Reliable, Rugged Moisture Gauge System for the Food Industry |
Each MCT466-SF moisture gauge system consists of a stainless steel gauge and a stainless steel Operator Interface. The gauge is normally located over a conveying system and is connected by a proprietary heat resistant cable to the Operator Interface. The Operator Interface produces 4-20mA, 0-10 vdc, RS232/485 outputs, along with bus connections such as Ethernet, Profibus, Modbus, etc. The MCT466-SF is made up of 5 basic components: a quartz halogen lamp, a filter wheel motor, multiple NIR interference filters in a rotating filter wheel assembly, a Lead Sulfide detector and a single “smart” circuit board. The MCT466-SF is fully modular – each of these components can be replaced in the field within minutes. The Near Infrared (NIR) Operating Principle Subsequently, the light reflected off of the product is captured by a mirror and focused onto a Lead Sulfide detector. The detector’s microvolt output is then taken by the on-board “smart” circuit board and converted into percent moisture or percent oil. |
