Performance
The ILSU is designed for use in continuous
submersion in liquids such as water, oil and
other non-aggressive chemicals. The
submersible uses the latest piezo-resistive
media-isolated silicon sensing technology and
a stainless steel diaphragm within a 316L
stainless steel housing.
It offers excellent stability, repeatability and
resolution, as required for use in rivers and
reservoirs. This submersible level transmitter
is the ideal product for reliable and repeatable
hydrostatic level measurement.
The electronics incorporate a microprocessor
based amplifier, requiring no adjusting and
giving stable electronics.
Each device is temperature compensated,
calibrated and supplied with a traceable
serial number and calibration certificate.
Custom versions can be made for particular applications.
