Non-contact sensors unaffected by echo
HiTECH Technologies' new line of compact, non-contact ultrasonic proximity sensors are based on echo pulse technology. The SonicLaserTM Ultrasonic Proximity Switches come in 18 different models and feature a patented, concentrated narrow beam angle of only 2.5 degrees off-center axis for reliable operation unaffected by interference from false echoes caused by surrounding objects. Measuring ranges vary from 3.28 to 26.25 ft depending on the model selected. The sensors operate in temperatures from -20 to 140F. Accuracy ranges from 0.08 to 0.2 inch. Applications include non-contact sensing of height, distance, continuity, presence, or absence of objects on trucks or railcars, or lift trucks and assembly lines and conveyors.

Transducer works in tough environments
Setra Systems Inc. introduces the Model GCT-225, a low-cost, ultra-high-purity pressure transducer for pressure-measurement applications that require insensitivity to environmental extremes, including high purity gas delivery systems, gas cabinets, and semiconductor process tools. The GCT-225 offers accuracy of ±0.25% FS and full scale pressure output of 0.2 to 5.2V dc or 4-20 mA output. The transducer measures gauge and absolute pressures from 0-25 to 0-3,000 psig or psia and compound pressures of -14.7-25 to -14.7-3,000 psig. A reduced height of 4.25 inches enables the GCT-225 to fit many applications, and its low cavity volume of 0.22 inch3 means the device is easily purged.

Steady, dry pressure gauges
Pressure gauges are getting a whole new look as Dresser Industries introduces a dry pressure gauge steady as a liquid-filled gauge--the Ashcroft Duragauge® PLUS! Liquid-filled gauges have been the standard for tough applications for 20 years, due to their reliability under high pulsation and vibration. But, says Dresser, they are harder to maintain than dry gauges and more expensive. The Duragauge handles vibration and pulsation better than standard dry gauges and fills a performance gap for those whose dry gauges may not last as long due to wear. The company reports that beta testing shows the gauge can last 100% longer than the conventional dry gauges. In addition, Duragauge PLUS! provides a steady pointer just as liquid-filled, but costs less. The patent-pending Duragauge PLUS! pressure gauge is certified at ±0.5% full-scale accuracy. Ranges include: 0/60 to 0/100,000 psi, 0/100 to 0/400,000 kPa, and 0/4 to 0/6,000 kg/cm2. Tube materials include phosphor bronze, 4130 alloy steel, 316 SS and Monel 400.

Say cheese for new uncooled IR cameras
Inframetrics (North Billerica, MA) introduces three new uncooled infrared focal plane array (FPA) thermographics cameras--Models PM 195, 295, and 395 of the ThermaCAM® X95 Series. The uncooled FPA detector technology includes what the company says is the first microbolometer detector designed specifically for precision temperature measurement in an uncooled IR imaging system. The ThermaCAM ULTRA X95 Systems provide long wave (8 to 12 micron) response, which makes them useful for general predictive and preventive maintenance work and outdoor inspections in sunlight. The cameras use a temperature-controlled detector radiation shield (patent pending), allowing extremely stable operation, expanded measurement ranges, and a significantly reduced need for internal image uniformity corrections. The device is palm-size and weighs just 4.4 lb.

Ready-to-use test software for wireless manufacturers
From a joint development with Hewlett-Packard and CommQuest Technologies comes the Total System SolutionTM for wireless manufacturers. The software offers what CommQuest says is the industry's first turnkey in-line production testing solution. The system bundles CommQuest custom test software, optimized for its chipsets, with Hewlett-Packard test equipment. The company claims the ready-to-use software package cuts up to 50% of cost from the testing process, and shaves months from design cycles by eliminating the need for custom software design.

Digital phosphor oscilloscope
Tektronix Inc. introduces a digital phosphor oscilloscope (DPO) that enables engineers to see, store, and analyze complex electronic signals. Tektronix's DPO is based on patented DPXTM technology. The company says DPX provides up to 1,000 times more signal data than digital storage oscilloscopes (DSOs), giving engineers more insight into the subtle patterns and behavioral variations of signals. DPOs differ from analog real-time oscilloscopes (ARTs) and DSOs, in that the digital phosphor oscilloscopes display, store, and analyze in real-time, using three dimensions of signal information: amplitude, time, and the distribution of amplitude over time. The benefit of this third dimension is an interpretation of the signal dynamics, including instantaneous changes in the signal and the frequency of occurrence. ARTs can display these three dimensions, but they cannot store or analyze them. Traditional DSOs only work with amplitude and time information, capturing infrequent snap-shots of less than 1% of the available signals.
