Vacuum gauge sensor prevents temperature drift

September 21, 2011 — InstruTech released its Cold cathode Ionization vacuum gauge CCM501, which the company is calling its Hornet module. The CCM501 is a rugged Cold Cathode gauge based on double inverted magnetron technology. It measures pressures from 1 x 10-8 to 1 x 10-2 Torr.

The electrometer auto zeroes to prevent temperature drift in readings. The sensor assembly can be easily disassembled and cleaned.

The standard CCM501 model includes OLED display, one analog output, one setpoint relay and RS485 serial communications. 16 common gases are pre-programmed into the user module. Users can also set warnings to alert for fault conditions. Anode voltage and ion current can be monitored in real time.

InstruTech makes microprocessor-controlled vacuum gauge sensors used in numerous vacuum measurement and control applications. Learn more at
