POTENTIAL APPLICATIONS
DESCRIPTION
• Industrial: Compressors, cylinder tank pressure, HVAC,
hydraulics, oil and gas, refrigeration, water distribution
• Transportation: Multiple applications including braking and
alternative fuels
• Medical: Anesthesia delivery machines, blood analyzers,
chemistry analyzers, gas chromatography, oxygen
concentrators, and ventilators
The MLH Series Heavy Duty Pressure Transducers combine
Application Specific Integrated Circuit (ASIC) technology
with a media-isolated, metal diaphragm designꢀ This digitally
compensated transducer offers value and performance,
making it a suitable pressure sensing solution for demanding
applicationsꢀ Industry standard electrical connectors and
pressure ports are offered for enhanced reliability and user
flexibilityꢀ
PORTFOLIO
The MLH Series joins the PX3 Series, PX. Series, SPT Series
heavy duty pressure transducers and the 13 mm Series and
19 mm Series heavy duty pressure transducersꢀ
The MLH Series has six standard output options:
• Ratiometric: 0ꢀ5 Vdc to 4ꢀ5 Vdc from 5 Vdc excitation
• Current: 4 mA to .0 mA
• Regulated: 1 Vdc to 6 Vdc
• Regulated: 0ꢀ.5 Vdc to 10ꢀ.5 Vdc
• Regulated: 0ꢀ5 Vdc to 4ꢀ5 Vdc

BFSL
• Total Error Band (TEB) as low as . ꢁFSS from -40°C
to 1.5°C: Provides indication of the transducer’s true
measurement performance over a specified temperature
range; small error promotes system uptime and efficiencyꢀ (See

Thermal Hysteresis
• All metal wetted parts allow for potential use in a wide variety
of fluid applicationsꢀ
• No internal elastomeric seals eliminate O-ring compatibility
issuesꢀ
• Amplified outputs reduce the need to purchase external
amplifiersꢀ
• Input reverse voltage protection guards against mis-wiringꢀ
• Less than . ms response time provides more accurate, high
speed measurementꢀ
