3 Fllng level and Temperature Sensor HFT C4 / R / MD Applcaton Desgned for measurements n fountans, basns and Use open or closed pressure-free contaners Pressure transducer for fllng level and temperature detecton for suspended nstallaton from the top or nstallaton n the ppng. Comprehensve operatng and dsplay optons wth relay, sgnal output 0/4-20 ma or Modbus RTU connecton Functon The hydrostatc pressure s regstered by a ceramc transducer made of AL 2 O 3. In addton, ths system s equpped wth a temperature sensor. The values are converted n the connecton housng. The output values can be ndcated by the UNI dsplay and/or transmtted va the respectve outputs. Versons C4: The current module transmts pressure and temperature va normalsed 0/4 20 ma sgnals. R: The relay module s equpped wth four programmable relay outputs. It s partcularly sutable for the drect control of senstve plant components, e.g. for dry run protecton of pumps or ndependent fllng level regulaton n contaners. MD: The Modbus module enables data bus communcaton. It contans two addtonal freely programmable relay outputs whch can be used for drectly ntervenng n the process f necessary. Type HFT Compact as compact one-pece varant HFT Flex wth the sensor separate from the connecton housng, connected by a 7 m long sensor cable Interfaces Sgnal output, current loop (C4): 0/4 20 ma Output can be calbrated/adjusted Sgnal output, relay (R): 4 relays, 5 A / 230 V AC Programmable NC/NO swtchng functon 2 nputs Sgnal output, Modbus RTU (MD): RS485 2 relays, 1 A / 30 V AC/DC 2 DC solated nputs Operaton 4-wre current verson (C4): usng the ntegrated potentometer, optonally usng the dsplay and control unt (dsplay) Relay verson (R): usng the dsplay and control unt (dsplay) Modbus RTU verson (MD): usng the dsplay and control unt (dsplay), relay / nputs va Modbus Measured varables Pressure (fllng level) and temperature Devce connecton Socket end for solvent weldng (PVC-U): d32 Fuson socket end (PVDF or PP): d32 Fuson spgot end (PVDF or PP): d32 Voltage supply U = V DC Cable connectons Cable outsde dameter: 5 11 mm Nomnal cross-secton, voltage supply: 0.25 mm 2 Nomnal cross-secton, relay outputs: 0.5 mm 2 Nomnal cross-secton, gate nputs: 0.25 mm 2 Nomnal cross-secton, Modbus: 0.35 mm 2 Materals, wetted parts Sensor: AL 2 O 3 96 % Sensor housng: PVC-U, PVDF or PP Sensor seal: EPDM, FPM Sensor cable, Flex verson: FEP Cable fastenng elements: PVDF Cable fastenng seals, FEP cables: FPM Devce connecton: HFT Compact Unon end and unon nut: PVC-U, PVDF or PP Sealng: EPDM, FPM 3
