A new electronic circuit for a hot-cathode ionization gauge
- 14 Downloads
Details are given of a circuit, capable of measuring pressures in the range 103 mm Hg to 1010 mm Hg. As the quotient of ion current over emission current is measured, which is proportional to the pressure in the abovementioned range, the need for an emission stabilizer has been eliminated. At pressures lower than 104 mm Hg, meter indication varies by not more than 3% at emission currents between 10 υA and 1 mA.
