Electrical/Electronics . . . SENSORS & TRANSDUCERS
Linear position sensors. Miniature 9600 Series linear position sensors incorporate reliable analog signal technology in a rugged electromechanical design to deliver precision feedback in delicate laboratory applications or harsh environmental conditions. Compatible with all industry-standard terminations, the Miniature 9600 series also suits applications in industrial, medical, aerospace, manufacturing and robotics. Available in three standard stroke lengths of 0.5-, 1- and 1.5-in., the device's plastic element is within a chemically-resistant housing that measures 0.35- by 0.5-in., with lengths of 1.06-, 1.56- and 2.06-in. They are designed to provide readings over temperatures of -40° to 135°C, vibrations of 15 Gs @ 50-1,000 Hz, and humidity levels of 95% @ 38°C.

Low pressure sensors. Model 265 Series transducers, produced
for the HVAC market, provide positive and negative pressure sensing required for high
efficiency air control systems, detecting from ±0.1- up to 100-in. of water column FS.
They are suited for static pressure and air velocity control, environmental pollution
control, stack gas monitoring, furnace control, clean room and isolation ward
pressurization, and medical instrument applications. Setra Systems Inc, Boxborough,
MA.
Temperature sensors. These probe assembly devices are
primarily thermistor based, but also include thick film, RTD and transistor packages. The
line is designed to handle a variety of surface, air and immersion applications in
aerospace, appliance, on-vehicle, industrial, medical and other markets. The devices are
available in a wide range of resistance and tolerance levels, a variety of rated operation
temperatures, and an assortment of package configurations. Invensys Sensor Systems, Pawtucket,
RI. 
Angle measurement. The AccuStar II DAS-20 dual-axis clinometer
combines two sensors in one package. Designed to compete with less-capable mercury
switches and low-cost level sensors, the DAS-20 produces an output signal proportional to
the relative tilt of two axes at right angles to one another. DC-powered, the unit has a
range of ±20 degrees in both axes, is repeatable to within ±0.1 degrees, and has a ±0.2
degree linearity. Schaevitz Sensors, TRW Automotive Electronics, Hampton,
VA. 
Ultrasonic sensor. The UDDK 30 is an ultrasonic sensor with
teach-in that can "learn" to fade out interfering objects, simplifying
installation and operation on the factory floor. The sensor features an elliptical
measuring area with an opening angle of 8 degrees and a one-touch set-up. The UDDK 30 can
be taught to ignore interfering objects between the sensor and the target, thus allowing
detection of objects through a grid or narrow opening. Baumer Electric Ltd, Southington,
CT. 
Rack mounts. The KµDA sensing system is being offered in a 19
in. Eurocad rack that can hold up to four dual-channel measuring modules. The units
feature high-performance eddy current sensing technology that makes precise displacement
measurements, and performs math and other user-defined functions to capture and analyze
events. The unit allows single-point RS-485 communication connection with alternate
individual RS-232. Kamen Instrumentation, Colorado Springs, CO.
