4.1.1 Flow controller for induction furnace operation
Gas flow controller adjustment
Fig. 55: Gas flow controller
–
Set the flow rate with P1 of the HF 42, to about 180 l/h. Observe the flow rate on the
lower flow meter of the analyzer. Wait until the value is stable.
The output of the flow sensor is on TP10 of the HF 42 board; TP15 is GND. With a flow of
180 l/h, the voltage is about 2.5 - 3V.
NOTE
: without flow, the output voltage of the sensor is not 0V but about 0.6V.
–
Adjust with P3 until the voltage on TP7 is 5V.
On TP8, the activity of the pulse width modulator can be checked.
The output voltage to the gas flow regulation valve can be measured on TP3.
With a constant flow of about 180 l/h, it should be between 5 and 15 volts.
–
Check and if necessary readjust the pressure regulator (PR3) in front of the flow
regulating valve.
