The external mount hydrostatic level

transmitter, ILSE, has a piezo-resistive

silicon pressure sensor which is an oil-

filled isolated diaphragm. The sensor and

housing are made from stainless steel with

a choice of internal O ring seals to ensure

the product is suitable for a wide range of

applications.

The electronics incorporate a

microprocessor based amplifier, requiring

no adjusting and giving stable electronics,

especially in high vibration/shock

applications.

Every device is temperature compensated,

calibrated and supplied with a traceable

serial number and calibration certificate.
