DESCRIPTION
MLH Series pressure sensors combine Application Specific
Integrated Circuit (ASIC) technology with a media isolated,
metal diaphragm design. This digitally compensated sensor
offers value and performance, making it the ideal pressure
sensing solution for demanding applications. Fully temperature
compensated, calibrated and amplified, the MLH is available in
50 psi to 8,000 psi pressure ranges.
MLH sensors deliver ±0.25% full scale accuracy Best Fit
Straight Line (BFSL) and as low as 2% total error over a
temperature range of -40 °C to 125 °C [-40 °F to 257 °F].
Industry standard connectors and process ports are offered for
enhanced reliability and user flexibility.
FEATURES
All metal wetted parts for use in wide variety of fluid
applications
No internal elastomeric seals mean no o-ring compatibility
issues
Amplified outputs eliminate cost of external amplifiers
Input reverse voltage protection guards against mis-wiring
Less than 2 ms response time provides accurate, high
speed measurement
Rated IP65 or better for protection from harsh environments
The MLH has six standard output options:
A. 0.5 Vdc to 4.5 Vdc ratiometric from 5 Vdc excitation
B. 4 mA to 20 mA
C. 1 Vdc to 6 Vdc regulated
D. 0.25 Vdc to 10.25 Vdc regulated
E. 0.5 Vdc to 4.5 Vdc regulated
G. 1 Vdc to 5 Vdc regulated
POTENTIAL APPLICATIONS
Compressors
Refrigeration and HVAC/R
General industrial
General hydraulics
Multiple transportation applications including braking and
alternate fuels
Medical
