Permissible Load
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.
Mechanical Dimensions
The IWSL is designed for use in continuous
submersion in water. The probe uses a
piezo-resistive silicon sensing technology,
isolated from the media by 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.
