Baumer Oil Level Switch
.
Designed for Reliability
The new Baumer Oil Level Switch brings capacitive frequency
sweep technology to the agriculture and construction industry.
This Baumer Oil Level Sensor is superior to established tech-
nologies, such as float switches, fixed frequency capacitive and
electro-optical level sensors. This sensor’s automotive grade
design can be easily integrated into any fluid reservoir. The Baumer
Oil Level Switch is factory pre-set for all sorts of oils such as
hydraulic oil and tractor fluids.
Oil Level Switch Benefits
Efficiency: Increased equipment productivity due to less
arbitrary interruptions
Cost Reduction: Less serious damage, less maintenance cost
and reduced repair downtime due to adequate alerts and
diagnostics
Time to Market: Faster development due to easy design-in and
automotive grade product design and qualification
Oil Level Switch
Advantages
Does not fail to warn even if
oil sticks to sensor
oil drizzles on sensor
No false warnings even if
oil is aerated
bubbles are present
there are particles in oil
there is turbulent flow in oil
Easy system integration as sensor can be mounted at
any location with standard O-Ring port
Field proven, hermetically sealed plastic housing in
automotive grade and standards based design
Technical modifications and errors reserved.
