Needle Valve Controller
The main component is an Eurotherm 2216e controller configured as a motorized
valve controller. The box contains also a bipolar power supply used for the
the pressure sensor and a netowrk of resistors and diodes for the asymmetric
power supply of the DC motor. The motor current is limited to 40/50 mA for
closing/opening and may be reduced by means of a resistor in the motor box.
