2.3 Product Description
The VSP/VCP vacuum transducer is measuring total gas pressure in the range of
1.0x10
-4
- 1000 mbar. Transducer type VCP with Pt/Rh filament is suitable for many
applications with corrosive gases in the range 5.0x10
-4
- 1000 mbar. The transdu-
cer can be connected to Thyracont display and control units or to customer related
power supply and evaluation units in compliance with pin assignment.
The analog output signal 1.5 V - 8.5 V of VSP and 2.2 V - 8.5 V of VCP, respectively,
has a logarithmic dependence on pressure over the whole range.
In addition the device has a serial RS485 interface for digital data transfer (see
section 5.1).
The VSP/VCP is equipped with a metal-sealed sensor type Pirani and temperature
compensated. It can be mounted to suitable flange connectors.
Proper Use
The VSP/VCP serves exclusively to provide absolute pressure measurements in
gaseous media. It may only be connected to components specifically provided for
such purpose.
Improper Use
The use for purposes not covered above is regarded as improper, in particular:
−
connection to components which are not specified for in their operating in-
structions
−
connection to components containing touchable, voltage carrying parts.
No liability or warranty will be accepted for claims arising from improper use.
The user bears the responsibility with respect to the used process media.
VSP: The device is not designed for use in corrosive gas atmos-
phere. Aggressive media such as halogenides, carbon or oxygen
plasma can reduce sensor life-time!
VCP: Aggressive media such as fluorides can reduce sensor life-
time!
Dust, oil or condensing vapours will affect sensor performance and
may cause malfunction!
