Sensors

If you have a demanding molding and/or assembly job that requires the ultimate in machine orientation, Sherborne Sensors Inc. (Wyckoff, NJ) would like you to take a look at its T700 series of solid-state MEMS inclinometers. The company claims the sensors enable high-precision inclination measurements with accuracies better than 1 milliradian over angles of ±30° to ±90°.

Automatic detection of the melt front using cavity pressure sensors can now be used to initiate reliable, fast, and automatic switchover to holding pressure thanks to a patent-pending development at sensors and process controls supplier Priamus System Technologies AG (Schaffhausen, Switzerland). However, the company believes the biggest impact of this development will be in automatic hot runner balancing where not only temperature sensors, but now also pressure sensors can be used.

Melt pressure in front of the injection screw is an important process parameter for precision processing and machine control is critically dependent on its precise measurement. This is because injection molded components can only be kept within extremely tight tolerances if this pressure can be accurately and repeatably measured and recorded over an extended period.

Able to measure infrared radiation from up to 10 ft away and thus be mounted far from harsh environments, the new FT Series digital infrared sensors from Keyence Corp. of America (Wanaque, NJ) are designed for easy noncontact detection of a part’s surface temperature. An optional air purge enclosure eliminates dust buildup, increasing sensor stability and decreasing process downtime. The ergonomically designed amplifiers can be panel mounted for easy temperature viewing and setup, or cabinet mounted on a DIN rail.

U-Gage M25U ultrasonic sensors from Banner Engineering Corp. (Minneapolis, MN) are specifically designed for use in sanitary environments. The sensors, rated IP69K and IP67 (NEMA 6), are constructed of heavy-duty 316 stainless steel to withstand the recurring high-pressure washdowns, severe temperatures, and aggressive cleaning chemicals common in food and beverage applications.

Cognex (Natick, MA) has added the Checker 3G Series to its Checker vision sensor product line. With simple setup, integrated part detection, lighting, I/O, and job change all in a rugged IP67 housing, Checker 3G is said to be an easy, reliable, and affordable way to verify all products or parts on the line.
