IWSL series
Water approved Submersible Level Transmitter - Silicon Sensor
Piezo-resistive sensor
Stainless steel body and diaphragm
Accuracy <0.1% FS BFSL (0.06% option)
Various outputs including mV, Volts and mA. Others are available.
Pressure ranges from 1mWG to 100mWG
WRAS Approval pending
Options available on the IWSL transmitter.
Pressure range and engineering units
Pressure reference (Gauge or Absolute)
Output type
Accuracy level (non-linearity and hysteresis)
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.
Suitable applications
River level
Reservoir level
Tank level
Borehole level
Aquifer level
Environmental monitoring
V-notch weir flow measurement
Performance
Accuracy (Non-Linearity)
Hysteresis
Setting Errors (offsets)
Permissible Load
The electronics incorporate a
microprocessor based amplifier, requiring
no adjusting and giving stable electronics.
Output Resistance
Influence Effects
Each device is temperature compensated,
calibrated and supplied with a traceable
serial number and calibration certificate.
