OEM PRESSURE TRANSDUCER
The model ML pressure transducer combines
the latest in ASIC technology with our proven
stainless steel design. This digitally compensated
transducer offers an unparalleled value and
performance combination making it the ideal
pressure sensing solution for demanding
automotive and industrial applications. Fully
temperature compensated, calibrated, and
amplified, the ML is available in 100 to 5000
PSIS pressure ranges.
The ML has three standard output options:
a 0.50 to 4.50 Vdc ratiometric output from
5 Vdc excitation, a 1.0 to 6.0 Vdc regulated out-
put from 7-35 Vdc excitation, and a 4-20 mA
current from 9-35 Vdc excitation. The ML
transducer delivers
±0.25%
full scale accuracy
(BFSL) over a wide temperature range of -40°C
to 105°C and utilizes a proven industry standard
connector for high reliability and user flexibility.
