Online and Lab NIR Moisture Sensors
The IR3000 online moisture sensor was developed for instant, noncontact analysis of powder and granular materials for the harshest environments. Insensitive to material variations such as particle size and material height, the unit provides continuous, accurate readings, allowing operating personnel the ability to make immediate process adjustments based on real-time measurements. The net result is improved quality and reduced production costs by saving in energy and waste. The 858 is an at-line, lab moisture analyzer that uses a patented optical technique and touch screen PC. The broad-beam instrument is designed to measure sealed samples in 1 second with no constituent losses due to volatilization, which results in a true moisture reading and accuracies within 0.01%.

Loop-Powered Level Switch
This explosionproof level switch has a wide tuning range and ability to ignore product buildup on the probe. Powered by 16–32 V dc, the output is 8 mA when the probe is in air and 16 mA when product is touching the probe. An internal jumper for reverse acting output is standard. Onboard power and calibration LEDs mean the only tool needed to set up this unit is a small screwdriver. The two-wire design makes installation quick and easy for plants having spare cable pairs. Interfacing with a PLC makes this unit ideal for OEM equipment. The probe is Type 316 stainless steel and is available in exotic materials of construction.

Bulk Flow Monitor
The Series BFM bulk flow monitor provides effective monitoring for most flow/no-flow conditions in pipes and chutes. Its sensing techniques, which use both microwave and Doppler, make it versatile for most applications. The control offers a number of advanced features. The BFM central processing unit monitors movement of almost anything through a pipe or chute system. It senses the presence or absence of materials in a pneumatic air system and offers adjustable sensitivity depending on the application demand. It provides easy installation and requires no maintenance. The unit has LED indicators: flow (green)/no-flow (red).

Multichannel Particulate Monitor
This multichannel particulate monitor is suited for monitoring multicompartment fabric filter baghouses, multichamber cartridge dust collectors, multiclone cyclones, and clusters of bin vents. For large fabric filters in the combustion industries, such as coal burning power plants, cement plants, trash incinerators, and foundries, the multichannel system has proven to be a superior control device to an opacity monitor in the stack. For pulse-jet filters, leak locating can be added as an option. The system employs field-proven induction-sensing, protected-probe, and automatic self-check technologies to provide high reliability and simple operation. The rugged modular design allows for easy expansion and upgrades.
