data sheet ffk? optical differential pressure (flow) transmitter ffi system the model ffk 3 optical differential pressure (flow) transmitter measures differential pressures (flow rates) of various fluids accurately, converts them into optical digital signals and outputs them. this is an intelligent transmitter providing excellent performance and functions due to in- corporation of electrostatic capacitance type silicon sensor and microprocessor. a fiber optical cable used for the signal transmission line forms an optical field instrumentation system together with an optical star coupler and a master station. features 1. resistive to noise and lightning optical signal ensures a reliable signal transmission, be- cause it is not be affected by external noise and induc- tive lightning. use of a nonmetallic optical (fiber) cable prevents propagation of inductive lightning through the cable, so a signal transmission immune to lightning can be realized. 2. reliability due to redundant configuration host system can be duplicated by using two optical cable trunk lines (between an optical star coupler and host system. this enhances reliability of users?systems. 3. intrinsic safety type explosion-proof each equipment with a built-in battery can be constructed so as to be an intrinsic safety type individually (intrinsic safety type barrier unnecessary). specifications functional specifications fluids measured: liquid, gas or steam measuring range and operating pressure: type minimum value maximum value lower range limit upper range limit ffk m 11 ffk m 22 ffk m 23 ffk m 25 ffk m 26 ffk m 33 ffk m 35 ffk m 36 ffk m 38 ffk m 43 ffk m 45 ffk m 46 ffk m 48 operating pressure [mpa] - 0.1 to +3.2 - 0.1 to +10 - 0.1 to +10 - 0.1 to +10 - 0.1 to +10 - 0.1 to +16 - 0.1 to +16 - 0.1 to +16 - 0.1 to +16 - 0.1 to +42 - 0.1 to +42 - 0.1 to +42 - 0.1 to +30 span [kpa] range limits [kpa] 1 6 32 130 500 32 130 500 3000 32 130 500 3000 1 6 32 130 500 32 130 500 3000 32 130 500 3000 - 1 - 6 - 32 - 130 - 500 - 32 - 130 - 500 - 3000 - 32 - 130 - 500 - 3000 0.1 0.15 0.8 3.25 12.5 0.8 3.25 12.5 75 0.8 3.25 12.5 75 date EDS6-125 may 20, 2004
