WATER LEVEL SENSOR SHAFT ENCODER - T039 TIDROM

Measure principle: A conventional float system drives an absolute shaft encoder with digital output in Gray code(25 bits). A microprocessor based electronic module provides different outputs proportional to the hydrometric level.
Intelligent sensor: The transducer belongs to the intelligent sensor family and allows, among other functions, the correct control functioning, data pre-processing, electrical signal A/D conversion etc.
These characteristics warrant excellent accuracy, long-term stability and high data reliability.
It can be provided with an interface for data recording on removable memory card which can downloaded by a portable PC or withdrawn for next reading in the office .
Laboratory calibration: The sensor can be supplied with a SIAP+MICROS calibration certificate or with calibration certificates issues by external primary metrological services .
Housing materials and International standards: A compact and robust die casting housing grants a IP 67 protection .
The transducer complies with CE EMC standards, it’s protected against over tensions and is fully compliant within the WMO (World Meteorological Organization) standards.
