Description

Function A turbine rotor is mounted in a stainless steel housing on two rotor shafts. The material of the bearing is either PTFE or tungsten carbide. That means even aggressive or slightly abrasive fluids can be measured. The medium passes through the turbine blades, causing the rotor wheel to rotate at a speed proportional to the velocity of the fluid. As each rotor blade passes through the magnetic field generated by the transducer a voltage output is created. A preamplifier converts the sinus wave into a square wave signal. Explosion-Proof Design (ATEX) • All turbine flow meters are available in explosion-proof design according to ATEX. • The explosion-proof design consists of the turbine flow meter (intrinsically safe electrical apparatus) and the switching amplifier K 130 (associated electrical apparatus). The type of protection „intrinsic safety“ applies to this construction. • The turbine flow meter is installed in the potentially explosive atmosphere. • The mounting of the amplifier K 130 is carried out in the safe area. • Turbine flow meter and switching amplifier are electrically connected to each other. The switching amplifier evaluates the sensor signals and converts them to square-wave signals. • Without switching amplifier, the turbine flow meter must not be operated in the potentially explosive atmosphere. • Cable lengths of up to 400 m are possible between turbine flow meter and switching amplifier. • LED’s for monitoring line breaks / short circuits, channel switching state and power supply are located on the switching amplifier.
