3 Product description
3.1 Function
3.1.1 Pirani measuring system
Within certain limits, the heat conductivity of gases depends on the pressure. This physical occurrence
is utilized in the Pirani thermal conductivity vacuum gauge to measure the pressure. A thin wolfram wire
with high temperature coefficients is used as the measuring element. With a suitable control circuit, the
resistance of the wire and thus its temperature are kept constant. The electrical power that is fed to the
wire is a measure for the heat power dissipated in the gas through heat conduction and therefore a
measure of the pressure.
3.1.2 Cold cathode measuring system
The current that flows into a self-sustaining gas discharge with cold cathode (similar to Penning) de-
pends on the applied voltage, the composition of the gas and the pressure. A magnetic field penetrates
into the measuring room that causes the electrons on the spiral trajectories to move from the cathode
towards the anode, and as a result perform a sufficient number of ionizing impacts to maintain the dis-
charge, even with low gas density. If the anode voltage and magnetic field are now kept constant (with
known gas type), the discharge current is a measure for the pressure.
3.2 Identifying the product
You will need all the data from the rating plate to safely identify the product when communicating with
Pfeiffer Vacuum.
1. Read the data on the product rating plate.
2. Record this data.
3. Always have all rating plate specifications to hand.
3.3 Structure of the plug-in boards
Pirani measurement boards
When the total pressure measuring and control unit is switched on, the Pirani measuring circuits are al-
ways in operation. The analog signals are always available, irrespective of the pressure display.
Pirani measurement boards have:
●2 independent fine vacuum measuring circuits, each with
─1 gauge power supply plug
─2 calibration potentiometers
─1 analog signal output
Cold cathode measurement boards
When the gauge is switched on, the analog signals are always available, irrespective of the pressure
display. This measurement board has special electronics that limit the measurement current to 100 μA.
This results in a considerably longer service life for the gauges.
Cold cathode measurement boards for high vacuum have:
●2 measuring circuits, each with
─1 gauge power supply plug
─1 analog signal output
Pirani/cold cathode measurement boards
The properties of these measurement boards correspond with the Pirani and cold cathode measure-
ment boards. The measurement boards for the range 10-10 hPa (CP 300C10) and 10-11 hPa (CP
300T11 and CP 300T11L) have special electronics that limit the measurement current to 100 μA. This
results in a considerably longer service life for the gauges.
Pirani/cold cathode measurement boards have:
●1 Pirani measuring circuit
●1 cold cathode measuring circuit

Interfaces and relay boards
There are 4 types of interface and relay boards:
●2 with RS-232-C interfaces
●1 with RS-422 interface
●1 with Profibus-DP interface
All 4 types each have 5 relays with potential-free switching contacts. The types each have a different
switching voltage for the relays and different interface connections.
3.4 Interfaces
3.4.1 "OUTPUT" connection on PI 300 and CP 300
Each measuring circuit has an analog signal output. Suitable plugs are included with each measure-
ment board.
