Rod-Style Actuator

The RSA-HT high-force rod-style actuator from Tolomatic (Hamel, MN) can also be considered as a replacement for hydraulic applications and offers maximum force capabilities of 12,900 lbf (57.38kN). Features include an IP67 option, standard purge/breather port, and a lubrication system. The actuator includes a grease zerk for lubrication without disassembly. The purge/breather port allows positive pressure to be applied to the actuator to help keep contaminants out, and functions as a breather port in high-speed applications where internal pressures may exert additional forces on the actuator if sealed.

Controller Systems

Velmex (Bloomfield, NY) offers VXM controller systems for power systems that drive motorized products including slides and rotary tables. The controller is a 2-phase, unipolar stepper motor controller that can drive and control precise movements, multi-axis, and velocity. The system is capable of controlling up to four motors, one motor at a time. Two motors can be controlled simultaneously for coordinated motion. Features include an intuitive, comprehensive command instruction set; single-chip microcontroller that digitally controls the motor phase switching and all other interface functions; elimination of noise-sensitive step and direction translation circuitry; and resonance-free motor torque from modulated current control.

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.
