Brushless DC Motor and Control

Groschopp (Sioux Center, IA) offers a brushless DC motor and control package consisting of brushless DC motors and gearmotors. The motors feature closed loop controls to deliver commutated power and variable speed control, maintaining speed regulation over a wide range of loads. The motors feature 2,600 to 3,800 RPM, 1.8 to 10.8 in-lb torque, 1/7 to 1/3 HP, and aluminum frames. The controls offer closed-loop speed regulation, line and low voltage, and chassis mount and NEMA 4X enclosures. Available options are a holding brake, foot mount, and IP66 compliance.

Computed Tomography Systems

JG&A Metrology Center (Detroit, MI) introduced increased flat panel sizes for computed tomography (CT) systems. Cone beam systems now utilize flat panel technology and scan parts up to 14" (350 mm) in diameter. With increases in LDA sizes as well, the CT systems use line detector array technology when scanning parts up to 26" (650 mm) in diameter. The equipment is used to provide 3D internal part inspection using industrial CT equipment.

Data Acquisition and Control

Dataforth Corp. (Tucson, AZ) introduced the MAQ20® industrial data acquisition and control system that features an analog resistance input module for channel protection. It interfaces to three types of 3-wire sensors: 100Ω Pt, 120Ω Ni RTDs, and potentiometers up to 5kΩ. The module has six input channels, each of which is protected up to 240 Vrms continuous overload in case of inadvertent wiring errors. Overloaded channels do not adversely affect other channels in the module. Transient protection is per the ANSI/IEEE C37.90.1 standard; input-to-bus isolation is 1500Vrms. The system can individually configure channels for sensor, range, alarm limits, and averaging. While all channels are enabled by default, those not used can be disabled to increase the sampling rate of channels enabled for scanning.

Digital Meter

The New Technology Meter (NTM) digital meter from OTEK Corp. (Tucson, AZ) measures and controls processes while operating with less than 50mW of power. It features a full tricolor bargraph with 2% resolution and four alarm set points. The meter includes isolated serial I/O, isolated O.C.T. or SPDT relays, and isolated analog output with P or PID algorithm. Signal failure (open or short) detection with date and time transmission is included. The meter is available in over 30 different input signals in loop or signal powered versions. The meter replaces fit, form, and function of any 6 × 1.74" panel cutout, and has up to two channels. It is available in an industrial plastic or a metal housing, and can meet nuclear or military grades.

Passive Oscilloscope Probes

The models 702902 and 702906 from Yokogawa Corporation of America (Newnan, GA) are 10:1 passive oscilloscope probes that operate over a temperature range from -40 to + 85 °C. They are suited for accelerated testing and validation methods where temperature cycling is part of the test procedure. The 702902 is designed for use with the isolated BNC input modules of Yokogawa’s DL850E ScopeCorder family; the 702906 is for use with the non-isolated BNC inputs of the DLM4000 and DLM2000 series of oscilloscopes.
