Function :

• The pressure adjusted at the pressure gauge for filling the gas remains fixed until it is changed manually or oxygen cylinder is replaced. Fix the nozzle of gas pipe on Combustion bomb and push a button on control unit.
  
• Gas will start filling the Bomb and supply will cut off automatically as soon as the adjusted pressure is achieved. This avoid the over filling of the gas in Bomb and thereby is a key feature towards the safety of the user.

We manufacture precisely engineered single phase servo voltage stablizer which essentially has a solid state circuit to control the servo motor. The motor is mechanically attached to the arm of a continuously variable auto transformer which feeds to the primary of a series control buckboost transformer. The stablizer output voltage is compared with the reference voltage and the resultant error signal controls the servo motor providing true proportional control systems rather than on / off circuits.
