The ILTSU is designed for use in continuous
submersion in liquids such as water, oil and
fuels. The probe uses the latest piezo-
resistive media-isolated silicon sensing
technology and a stainless steel diaphragm.
Housed within a 316L stainless steel, or
high grade Duplex stainless steel housing,
this submersible transmitter is the ideal
product for hydrostatic level measurement
where temperature is also a critical part of
the measurement.
It offers excellent stability, repeatability and
resolution, as required for use in rivers and
reservoirs.
This type incorporates a Class ‘B’ accuracy
platinum resistance thermometer.
Every device is temperature compensated,
calibrated and supplied with a traceable
serial number and calibration certificate.
