Stainless Steel Pressure Sensors
ST Series
FEATURES
• Amplified output which
eliminates the cost of
external amplifiers
• Reverse polarity protection
prevents damaged from
reversed excitation
• Less than 500 µs response
time for accurate high
speed measurements
• Exceeds CE Heavy
Industrial EMC
• High value with
outstanding performance
TYPICAL APPLICATIONS
• Pneumatic equipment
• Air compressors
• Air filtration monitoring
• Industrial controls
The Model ST pressure transducer combines Honeywell's proven silicon
pressure sensing with the latest in ASIC technology in a rugged, industrial
package. High value, coupled with outstanding performance, make this an
ideal transducer for industrial control applications such as air compressors
and pneumatic equipment. Temperature compensated, calibrated, and
amplified, the ST has pressure ranges from 0 psi to 5.0 psi to 0 psi to 250
psi.
The ST offers three standard output options for user flexibility, which are
as follows: a 0.50 Vdc to 4.50 Vdc ratiometric output from 5.0 Vdc excitation,
a 0.50 Vdc to 4.50 Vdc regulated output from 7.0 Vdc to 35.0 Vdc excitation,
or a 4 mA to 20 mA output from 9.5 Vdc to 35.0 Vdc. The ST transducer
delivers ±1.0% full scale accuracy (BFSL) over a wide temperature range of
-40 °C to 100 °C [-40 °F to 212 °F] and utilizes a proven industry standard
connector for high reliability.
