data sheet fqk water level transmitter this water level transmitter is used for measuring the level of clean water, sewage water, well, river, etc. the detector is placed on the bottom of the water, and the water head pressure acting on the pressure receiving diaphragm is detected, converted into a current signal and then transmitted to a receiving instrument via the connector terminal. features 1. accuracy as high as 0.2 % excellent performance has been realized with a highly evaluated capacitance type silicon sensor and a microprocessor. 2. powerful arrester built-in both detector and connector terminal are equipped with a lightning arrester to secure reliable lightning protection. 3. remotely adjustable this transmitter is remotely adjustable with a hand- held communicator. specifications measurement item : water level of clean water, sewage water, well, river, etc. (note: avoid a vicinity of chemical injection site.) measuring range: 0 to 1.5 ... 13 m 0 to 10 ... 50 m output: 4 to 20 ma dc power supply: 24 v dc (10.5 to 32 v) wiring system: 2-wire system allowable load resistance: 0 to 600 ? (at power supply of 24 v dc) note: a load resistance of at least 250 ? is required for communications with a hand-held communicator. remote setting: zero/span adjustments, range setting and damping setting (settable with a hand-held communicator.) communication line conditions (when using hand-held communicator): line length; max. 2 km load resistance; 250 to 600 ? load capacity; 0.22 f or less load inductance; 3.3 mh or less saturation output: upper limit: 20.8 ma, lower limit: 3.8 ma damping: time constant variable within 0 to 32 sec (settable with a hand-held communicator.) zero and span adjustments: adjustable from connector terminal or remotely adjustable with hand-held communicator. zero point shift: 35% of maximum measuring range span adjustable range: 10 to 100% of maximum measuring range (measuring range must not be exceeded.) liquid contacting temperature (detector): 0 to 50?c ambient temperature ( connector terminal ): -20 to +60?c storage temperature: -30 to +70?c accuracy rating: 0.2% of measuring span allowable overpressure: up to 2 times of maximum measuring range temperature effect: (0.3 + 0.2 url / x) % /30?c url; upper range limit (13 or 50 m) x; actual measuring span material (detector): pressure receiving diaphragm; sus 316l outer tube; sus 316 hollow cable; pvc or pe covering detector connector terminsl date EDS7-65D apr. 1, 2011
