NEW PRODUCTS
Digital Pressure Transducer
The new Heise DXD digital pressure transducer
delivers the unique benefits of digital communication
at what the manufacturer says is a bargain price. This
instrument is now available with a LabVIEW driver and
new LabVIEW-based utility software that allows the user to
address, configure, and monitor one or more DXDs. The DXD is
offered in ranges from vacuum through 7,500 psi and features
an accuracy of ±0.02% of full span, which includes the effects
of temperature. A 10,000 psi range is also offered at an accuracy
of 0.1% FS. With update rates of up to 15 mS, dozens of DXDs can
communicate with a single PC serial port at speeds up to 115K bps via
full-duplex RS232 or RS485 communication protocol. The Heise DXD
features wetted materials and a rugged enclosure made of 300-series
stainless steel. (www.heise.com)
Hermetically Sealed Piezoelectric Accelerometers
Meggitt Sensing Systems introduced the Endevco model 7251A series, a family
of small, lightweight, hermetically sealed piezoelectric accelerometers with
integral electronics. The centrally located thru-bolt mounting hole of
this series provides both 360-degree cable and connector orientation,
allowing the sensor to offer a flat mounting surface, even when not
fully perpendicular, for ease of use in a variety of applications.
Available in standard model sensitivity ranges from 500 mV/g to 10
mV/g with optional high-temperature and TEDS versions, the 7251A
series incorporates an annular shear piezoelectric sensing element,
along with an internal hybrid signal conditioner, within a two-wire
system. The system transmits its low-impedance voltage output through
the same cable that supplies constant current power, with high-output
sensitivity and wide bandwidth, while exhibiting low base strain sensitivity
and excellent output stability over time. Weighing just 10.5 grams, it
effectively minimizes mass loading effects. (www.meggittsensingsystems.com)
Filters for Lower-Pressure Liquid and Gas Applications
Mott says its new 7710 Series filters are designed to accommodate lower-pressure
liquid and gas filtration applications at a value price point. Porous metal elements for
this model are 10-inch long, 316L stainless steel cartridges in either a double open
ended or 1-inch NPT connection configuration. The 316 stainless steel housing comes
standard with a Buna N housing seal to provide strength and dependability. Other seals
and O-rings are available to support applications requiring higher temperature or
corrosion resistance. The 7710 Series filters are designed for maximum
operating pressures of 300 psi (housing) and include a ¼-inch
NPT housing drain, ¼-inch NPT gauge ports, and
1-inch FNPT line connections. Outside-in filter
area is 0.54 square feet. (www.mottcorp.com)
