HAMPTON, Va., Sept. 25, 2014 /PRNewswire/ -- Measurement
Specialties (NASDAQ: MEAS), an expert in sensor design and
manufacturing, has now expanded its 154 Series of media isolated,
piezoresistive silicon pressure sensors with the small profile,
backside compensated 154B.

Housed in a 316L stainless steel package as standard, the
compact 19 mm sensor is also available in an ASTM Grade 2 CP
titanium housing for exceptionally harsh environments. This
broadens the 154B's uses from process controls, refrigeration and
compressors, hydraulic controls and fresh water measurement to
medical equipment, such as dialysis machines, as well as more
corrosive environments, including brackish and salt water.
The headerless design of the 154B enables a low-cost solution
for low pressure applications where the silicon die is attached
"upside down" directly to the module. The O-ring mountable
sensor is easily and securely incorporated into OEM applications
that contain corrosive materials or harsh cleaning
chemicals.
Standard ranges for pressure are from 0 psi to 15 psi up to 0
psi to 300 psi in gage reference format as well as from 0 bar to 7
bar up to 0 bar to 28 bar in absolute reference. The sensor
features a pressure non-linearity of +/-0.3% span with an overload
pressure of 2X rated (up to 500 psi) and a burst pressure of 3X
rated (up to 600 psi).
The unit's wide compensated temperature range spans from -20
degrees C to +85 degrees C, and has a typical zero pressure output
of 100 mV.
Silicon oil provides a stable, reliable transfer of pressure
from the sensing package diaphragm to the sensing element
itself.
A ceramic substrate with laser-trimmed resistors is attached to
the package to provide temperature compensation as well as offset
correction. An additional resistor is used to adjust an
external differential amplifier and provide span interchangeability
to within +/-1% for exceptional measurement accuracy.
