Applications

The PXSCX Series features an
integrated circuit sensor element
and laser trimmed circuitry in
a small PC board mountable
package. The PXSCX sensors are
internally calibrated and temperature
compensated to provide a stable
and accurate output over a broad
temperature range of 0 to 70°C (32
to 158°F). They are designed to work
with dry, non-corrosive, non-ionic
gases such as air and many common
industrial and laboratory gases. Their
fast 100 µsec response time makes
them ideal for pneumatic control
applications.

The DP25B-S is a low-cost digital panel meter
for use with voltage, current, or bridge-type
transducers. For bridge sensors, the DP25B-S
has a ratiometric input to correct for variations
in excitation voltage. Standard features include
a front-panel tare button and a peak hold
feature. Options include dual 5 A alarm relays
and a scalable analog output configurable for
0 to 10V or 4 to 20 mA.
