2.3 Product Description
The VSI vacuum transducer is measuring total gas pressure in the range of
2x10
-3 - 5x10 -9 mbar. The transducer can be connected to Thyracont display and
control units or to customer related power supply and evaluation units in compli-
ance with pin assignment. The analog output signal 2.199V - 7.801V has a
logarithmic dependence on pressure over the whole range.
In addition the device has a serial RS485 interface for digital data transfer (see
chapter 5.1).
The transducer is equipped with a metal-sealed combination sensor type Pirani /
Cold Cathode (inverted magnetron) and temperature compensated. It can be
mounted to suitable flange connectors.

components specifically provided for such purpose.
Improper Use
The use for purposes not covered above is regarded as improper, in particular:
- the connection to components not allowed for in their operating instructions
- the connection to components containing touchable, voltage carrying parts.
