WARNING
Personal Injury
Do not use these products as safety or emergency
stop devices or in any other application where failure
of the product could result in personal injury.
Failure to comply with these instructions could result in
death or serious injury.
General Information
All gauge sensors are vented to the atmosphere through a
case vent hole that is protected with a vapor inhibiting
material.
Pressure Overloads
CAUTION
Product Damage
Do not exceed the pressure overload rating.
Failure to comply with these instructions may result in
reduced life or electrical failure.
The MLH series pressure sensors will withstand high
overloads; however, if the proof rating is exceeded, the life of
the sensor may be reduced and electrical failure may occur.
Both static and dynamic overloads must be considered,
particularly in hydraulic system applications. Hydraulic
pressure fluctuations can have very high and very fast peak
pressures, as in a water hammer effect.
An oscilloscope is recommended for determining if high-
pressure transients exist in a system. If system pressure
pulses are expected, choose a sensor with a pressure rating
high enough to allow continuous operation at the highest
expected pressure spikes.
