Inc. announces the ST420, a loop-powered,
stainless-steel analog shaft tachometer. The ST420 requires no user
calibration, providing a dependable shaft speed monitoring solution right out
of the box. Only 18 mm in diameter, it reliably detects magnetic pulses from a
rotating shaft-mounted pulser disc or wrap. Then, the ST420 uses quartz
crystal-based digital processing to convert pulses to a smooth, continuous
4-20mA analog signal directly proportional to the pulse frequency. The result
is a plug-and-play solution that allows users to accurately and simply monitor
rotating shaft speed in industrial applications.
ST420 shaft tachometer has been tested by UL to the standards UL913 and CAN/CSA
C22.2 No 157-92 (Intrinsic Safety), assuring it provides an intrinsically safe
solution for Class I (Groups C & D) and Class II (Groups E, F & G)
environments, when used with an approved I.S. barrier. Its magnetic pulse
detector, signal processing capability and 2-wire loop-powered 4-20 mA
circuitry are combined into a stainless-steel M18x1 sensor housing. The ST420
resists harsh plant environments and is rated NEMA 4X/IP67.
both standard and custom measurement ranges, the ST420 facilitates precise
shaft speed monitoring in industries including:
The company says it anticipates high-definition video for home security and other uses will be the next mature technology integrated into the IoT domain, hence the introduction of its MatrixCam devkit.
Siemens and Georgia Institute of Technology are partnering to address limitations in the current additive manufacturing design-to-production chain in an applied research project as part of the federally backed America Makes program.
Most of the new 3D printers and 3D printing technologies in this crop are breaking some boundaries, whether it's build volume-per-dollar ratios, multimaterials printing techniques, or new materials types.
