The ILLS is designed for use in continuous
submersion in liquids such as water, oils
and fuels in small tanks, where
conventional mechanical level switches
and sensors are not ideal and more level
‘control’ and measurement is required.
The probe uses a piezo-resistive silicon
sensing technology, isolated from the
media by a diaphragm within the stainless
steel housing It offers excellent stability,
repeatability and resolution for
applications where a small tank level is
required, from as low as 1m through to 10
m high tanks.
Each device is temperature compensated,
calibrated and supplied with a traceable
serial number and calibration certificate.
Accuracy <0.5% FS BFSL
Pressure ranges from 1mWG to 10mWG
Custom versions can be made for particular applications.
