WORLD LEADER IN SENSING SOLUTIONS
PT SERIES
Combined
Pressure/Temperature Sensor
Similar to other TI pressure trans-
ducers, the voltage output is ratio-
metric to supply voltage. With a
data conversion circuit referenced
to supply voltage, accuracy can be
maintained regardless of supply
voltage variation.
Temperature: The temperature sen-
sor is an NTC thermistor (resistance
decreases with increasing tempera-
ture) with either 10KΩor 100KΩ
value @ 25oC. Unlike other integrat-
Texas Instruments’ PT series
pressure/temperature sensor
provides system designers with
twice the output information in a
single package, from the same
source point. Originally developed
for demanding under-hood
automotive environments, the PT
sensor is made to withstand the
rigors of today’s applications.
Pressure: The pressure transducer
is a 0-5 Vdc output design that
requires no end-user amplification.
Product Bulletin
ed packages, TI’s PT sensor places the
thermistor directly in the measurement
medium (fluid stream), which provides
a 50% faster response time and greater
accuracy over encased or pipe- mount-
ed thermistors.
Packaged with an AMP Micro-Quadlok
System™ connector, the sensor has a
steel or brass housing, and is available
in two standard pressure ranges:
0-150 or 0-500psi with a variety of
pressure fittings.
