MLH SERIES GAUGE PRESSURE SENSORS
3 62-0296—03
A pressure “snubber” may be used to reduce the peak
pressure applied to the sensor. Snubbers may be obtained
from the Mott Corp., Farmington, CT, USA [phone].
Catalog #4100-1/8-SS is recommended.
Media Compatibility
CAUTION
Product damage
Use non-abrasive, chemically compatible media to
prevent damage to diaphragm or port materials.
Failure to comply with these instructions may result in
product failure.
The MLH series pressure port and diaphragm is an assembly
of Haynes 214 alloy (or equivalent) and 304 stainless steel.
INSTALLATION
CAUTION
Product Damage
Use a hex wrench for installation. Never apply torque
to the connector housing or the body of the sensor.
Do not subject the sensor to high temperatures from
soldering, brazing, or welding of the system plumbing
or operating environments above the specified
maximum temperature.
Failure to comply with these instructions may result in
product damage.
A pigtail siphon should be installed to protect the sensor
element from damage that can occur from direct exposure to
high temperature steam.
Electromagnetic Energy/Noise
CAUTION
Product damage/erratic operation
Do not use in areas where electromagnetic energy
may affect sensor operation.
Failure to comply with these instructions may result in
improper operation and/or product failure.
The MLH series has been rated for high immunity to electrical
noise; however, care should be taken when used around high
voltage sources that emit high levels of radiated
electromagnetic energy like variable frequency motor drives,
solenoids, radio transmitters and engine ignition systems. The
use of shielded cable and grounding of pressure port is also
recommended.
