K-Factor Scaler F5140 and Programming Kit F5141
Contents
1. blades cuts through the magnetic field generated by the magnetic pick up which in turn generates a frequency output signal that is directly proportional to the speed of the rotor The signal produced is received by the K Factor Scaler input amplifier which has an input sensitivity of 30 mV p p to 30V p p The signal is then sent to an onboard microcontroller which acts as a divisor with a range of 1 to 999 999 999 The divisor K factor is user adjustable through the optional programming software kit The microcontroller handles the dividing process by counting the input pulses and comparing it to the programmed K factor value Once the count equals this value an output pulse occurs for a selectable time period and the counting process starts over In addition if the K factor is set to 1 the K Factor Scaler can be used as a pre amplifier where the frequency from a low level turbine meter is proportional to the logic level frequency output needed by a PLC or CPU data acquisition card This option allows the end device to control the dividing process of the turbine meter output to a recognizable flow rate SPECIFICATIONS External Power Input Voltage 8 5 to 30 Vdc Diode protected Maximum Current draw 18 mA using internal resistor 30 Vdc input Environmental Operating Temperature 22 F 30 C to 158 F 70 C Inputs Magnetic Pick up Input Frequency Range 0 to 4000 Hz Trigger Sensitivity 30 mV p p to 30 V p p Output2.

8. he K Factor board consists of the following four items Setting the K factor divider Setting the output pulse width Setting the output level normally high or normally low Setting the pulse to use the internal or external pull up resistor Setting the K factor The K factor is the ratio of input pulses per each output pulse and can be viewed as a divisor The minimum K factor can be set to 1 where each input pulse yields an output pulse The maximum K factor can be set to 999 999 999 where it would take this many input pulses to yield one output pulse The K factor is set by entering it into the Program Values column of the software under K Factor The K factor will be programmed into the board when the Program button is pressed but note that all values must be entered before programming is allowed by the software Setting the output pulse width The output pulse width is the length of time the pulse remains active before resetting to its resting state The K Factor has a total of six different pulse widths to choose from Some end devices require that the pulse be a certain length or longer in order for proper detection of each incoming pulse For these devices it s important to select a pulse width that is long enough for the end device to recognize The pulse width option is set by selecting the desired pulse width radio button in the Program Values column of the software The Pulse Width option will be programmed into t
