PORTFOLIO
The MLH Series joins the PX3 Series, PX2 Series, SPT Series
heavy duty pressure transducers and the 13 mm Series and
19 mm Series heavy duty pressure transducers.
Sensing and Internet of ThingsSensing and Internet of Things
DESCRIPTION
The MLH Series Heavy Duty Pressure Transducers combine
Application Specific Integrated Circuit (ASIC) technology
with a media-isolated, metal diaphragm design. This digitally
compensated transducer offers value and performance,
making it a suitable pressure sensing solution for demanding
applications. Industry standard electrical connectors and
pressure ports are offered for enhanced reliability and user
flexibility.
The MLH Series has six standard output options:
• Ratiometric: 0.5 Vdc to 4.5 Vdc from 5 Vdc excitation
• Current: 4 mA to 20 mA
• Regulated: 1 Vdc to 6 Vdc
• Regulated: 0.25 Vdc to 10.25 Vdc
• Regulated: 0.5 Vdc to 4.5 Vdc
• Regulated: 1 Vdc to 5 Vdc
VALUE TO CUSTOMERS
• Total Error Band (TEB) as low as 2 %FSS from -40°C
to 125°C: Provides indication of the transducer’s true
measurement performance over a specified temperature
range; small error promotes system uptime and efficiency. (See
Figure 1.)
• All metal wetted parts allow for potential use in a wide variety
of fluid applications.
• No internal elastomeric seals eliminate O-ring compatibility
issues.
• Amplified outputs reduce the need to purchase external
amplifiers.
• Input reverse voltage protection guards against mis-wiring.
• Less than 2 ms response time provides more accurate, high
speed measurement.
