Level sensors & software for inventory control.

At the big NPE show in Chicago, two suppliers showed off new bulk-material level sensors and inventory-control software. Bindicator, Spartanburg, S.C., showed its Mark-4 Yo-Yo weight-and-cable type of continuous level sensor (pictured), which is offered with optional web-based i-Level inventory-management software. The sensor is rated for hazardous environments and has RS-485 Modbus communication capability. Silos up to 100 ft tall can be measured with a resolution of i cm, the company says. Up to 99 sensors can be set up and monitored from a remote display. Tel: [phone] * PTDirect: 751DB

Monitor Technologies, Elburn, Ill., has expanded its product line with Flexar guided-wave radar sensors for continuous level measurement of pellets, powders, or liquids. It requires no field calibration, withstands high temperatures, and works with materials having a wide range of bulk densities and dielectric constants. It is compatible with the company's newest SiloTrack Version 3.5 PC-based inventory-management software.

Also from Monitor is SiloPatrol SE, a new version of its cable-based level sensor for bulk solids. Suitable for dusty, hot conditions, it uses Hall-effect sensing to provide measurement resolution to 3 mm, said to be an "industry best. "This sensor is also compatible with SiloTrack v. 3.5 soft ware Tel: [phone] * PTDirect: 173JX
