Oriental Motor U.S.A. Corp., Torrance, Calif.
Eaton Corp., Bethel, Conn.
The DLR334 series has been designed for use in test-stand monitoring in manufacturing and as a transfer standard for testing and calibration of pressure-sensitive devices. Three accuracy ranges are offered accommodating pressures from inches of water to 10,000 psi. All accuracy statements are specified as "of reading" and are available as 0.05, 0.1, and 0.25 percent. The series includes RS232, RS422, and RS485 digital outputs as well as scalable analog outputs.
Olson Research & Development, San Diego, Calif.
The model SC-01D displacement gauge has been designed for single-element (top-side) surface-
position measurement. The Model SC-02T thickness gauge is for two-element (top and bottom) thickness measurement. Accuracy levels of 2.5 microns are attainable even with 10 degrees F shifts in ambient temperature. The gauges work on conductive and nonconductive materials and can feed data into a spectral analyzer or PC-based data-acquisition device. They deliver 100 sample measurements per second at a distance of 0.250 in. from the surface of the material.
Windrock Inc., Knoxville, Tenn.
The Model 6300 analyzer for reciprocating-machinery performance and
mechanical-condition analysis has been designed to rapidly acquire dynamic and process measurements at the machine. Equipped with a comprehensive software program, the 6300 provides detailed graphical displays and reports
allowing users to analyze operating and mechanical conditions of engines and compressors. The system captures and displays up to four channels of data simultaneously, including real-time data such as pressure and vibration versus crank angle, vibration spectrum, temperature, angular velocity, and ultrasonic measurements. Functions include calculation of performance parameters, such as horsepower and capacity, and recall of historical data with current data.
Metabo Corp., West Chester, Pa.
A 500-W, variable-speed, reversing D-handled SDS chuck rotary hammer, Model Bh E 6015 S-R+L, features electronic speed control for continuous variation of speed. The hammer has a 4.5-A motor with a no-load speed range between 0 and 1,050 rpm, and 0 to 4,900 blows per minute with a force up to 1.6 joules. The hammer can be used as a standard drill by mounting an optional chuck and activating the percussion stop. Drilling capacity is 3/4 in. in concrete, 1/2 in. in steel, and 1 1/4 in. in wood.
Jergens Inc., Cleveland, Ohio.
Adjustable Micro Clamps permit a single hole location to accommodate clamps with distances to the part being held from 12 to 35 mm. The clamps feature a design with only two parts. A Òcam actionÓ is created by tightening a hardened-steel-socket cap screw with an offset head. The clamps are available with smooth or serrated faces.
Hudson Control Group Inc., Springfield, N.J.
Scott Specialty Gases, Plumsteadville, Pa.
The Scotty VI 57-L transportable cylinder features the
Aculife treatment process for long-term stability of reactive gas mixtures such as H2S. Also available is a high-pressure cylinder, the Scotty HP.
Jesco America Corp., Rochester, N.Y.
Mechanically actuated series 2200 and 2300 modular diaphragm pumps, previously sold under the Proportioneer label, are available. Now offered is
a four-step pulley drive, a double-
diaphragm design, and an optional
electronic-stroke control (4 to 20 mA, featuring 0- to 100-percent adjustability and a NEMA 4x rating). The pumps feature low stroking speeds and rugged construction. Eighteen pump sizes cover the maximum capacities from 1.3 to 640 gph at operating pressures up to 150 psig.
Exergen Corp., Watertown, Mass.
More than 300 models of noncontact infrared temperature sensors have been designed according to NEMA 4 and 4x specifications as intrinsically safe. A patented technology for the sensors is based upon a self-generating signal that requires no external power source. The sensors are made for OEMs, factory automation, and temperature-control applications.
Revere Transducers, Tustin, Calif.
The GP7000 series has been designed for the fluid-power market. The series incorporates thin-film, strain-gauge, and micromachined piezoresistive technologies. Because there is no adhesive used in gauge bonding, the output of the pressure transducer is stable over time and operating temperature ranges. The transducers are 1.12 in. in diameter and 2.75 in. long. Electrical output formats include 0 to 20 mV, 0 to 5 V, and 4 to 20 mA.
Pacific Scientific, Rockford, Ill.
Powerpac hybrid steppers feature high torques per frame size. A large rotor diameter and rotor/stator design combine with magnetics in ÒhousinglessÓ frames to produce high torque and high acceleration. Available in NEMA-34 and -42 frames, the steppers are offered in two series. The N series, with holding torques to 272.8 lb-in., is the standard. The K series has torque outputs up to 356 lb-in. Both have high torque-to-
inertia ratios.
Dwyer Instruments Inc., Michigan City, Ind.
Series SVP solenoid valves allow the control or regulation of flow in proportion to a 0- to 24-V dc variable-voltage input signal. Four models with different orifice sizes are available for Cv values ranging from 0.009 to 0.068. These enable maximum air flows from 7.4 to 53 scfh and water flows from 2 to 13.5 gph. The lightweight units can be supported directly by 1/4-in. metal-process tubing or secured to a fixed mounting surface via the 6 to 32 tapped threads in the base.
