The ir3000 moisture transmitter is useful to measure the moisture level in many types of pharmaceutical powder. By installing the moisture transmitter in the processing area, typically in the bowl of the fluid bed dryer, a manufacturer can continuously monitor the process, subsequently manually or automatically controlling moisture. The transmitter should he located looking into the fluid bed dryer bowl via a sapphire viewing window, which can be supplied by moisttech. The sensor bottom should be mounted at a 17 degrees angle to the window to get maximum light penetration onto the product. Typically the powder will bush against the viewing window to allow us to make a very good analysis of the moisture. Another location for the sensor is to mount in a falling stream of powder once it has exited the dryer. For this location the moisttech 3a sanitary powder sampler option can be applied. The sampler captures a sample of the powder allows this to be measured and returned to the process, without compromising the process. Measurement, wavelengths, algorithms and sensor optical requirements are all preset at the moisttech factory. Typical accuracy is about 0.05 to 0.1 percent moisture. Typical analogue range is 0-10 percent moisture. The transmitter analogue output can easily be adjusted to optimise plc or recording.
