2 Sensor-No.: WATERPILOT fth O 1,0 bar 10 mh O 15 psi 30 fth O bar mh O psi Function and System Design Measuring principle The is a submersible level transmitter with a ceramic pressure sensor for the level measurement of liquids. The Waterpilot is available with nine permanently calibrated measuring ranges from 3 to 600 fth O to ensure use in all standard applications (optional application specific range). Due to its compact outer diameter of only 0.87 ( mm), it is ideal for use in 1 well casings. Options include output for temperature measurement. The is a loop-powered self-contained 4 to 0 ma device. The hydrostatic column acts directly on the ceramic diaphragm. The deflection of the diaphragm generates a change in the capacitance of the sensor. The transmitter electronics, which is located in the 316L SS probe, converts the capacitance change to a repeatable and accurate 4 to 0 ma output signal. A complete measuring system consists of the and a transmitter power supply unit (10 to 30 VDC). has a complete line of power supplies with displays and/or indicators. p atm Ceramic measuring cell p atm p atm p = p atm +p hydr. Pressure compensation tube p hydr. h = level height p = total pressure = hydrstatic press. + atmospheric press. ρ = liquid density g = gravitational acceleration p hydr = hydrostatic pressure p atm = atmospheric pressure p hydr. = (p atm +p hydr..) p atm p = p atm +p hydr. h h p h = ρ p g Temperature measurement with Pt 100 (optional) offers an optional 4-wire Pt 100 resistance temperature sensor (Accuracy Classs B to DIN EN 60751) for the to measure level and temperature simultaneously. Temperature measurement with Pt 100 and temperature transmitter TMT 181 (optional) To convert Pt 100 signals into a 4 to 0 ma signal, offers a temperature transmitter for mounting in the terminal housing. The ceramic sensor is the key to optimum performance of the Waterpilot diaphragm with common counter electrode brazing preform and spacer basic substrate C-electrode Ceramic Sensor Advantage Ceramic Sensor Benefit Corrosion resistant to chemicals, Universal usage at no additional acids and alkalines cost, longer life span Diaphragm not sensitive to galvanic Long lasting measurement without corrosion extra cost Abrasion and dent resistant; Long-term use in abrasive slurries cleanable without damage.
