2.3 Product Description
The VSL vacuum transducer is measuring total gas pressure in the range of 1.0x10
-4
- 1200 mbar as well as relative pressure in a maximum range of -1060 ... +340 mbar.
The transducer can be connected to Thyracont display and control units or to
customer related power supply and evaluation units in compliance with pin as-
signment.
The relation of analog output signal 0 - 10 V and pressure is depending on which
pressure signal is assigned.
In addition the device has a serial RS485 interface for digital data transfer (see
section 5.1).
The VSL is equipped with a metal-sealed combination sensor type Piezo / Pirani
and temperature compensated. It can be mounted to suitable flange connectors.
Additionally the gauge operates a piezo-resistive sensor for measuring ambient
pressure.
Proper Use
The VSL serves exclusively to provide absolute and relative pressure measure-
ments 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.
The device is not designed for use in corrosive gas atmosphere.
Aggressive media such as halogenides, carbon or oxygen plasma
can reduce sensor life-time!
Dust, oil or condensing vapours will affect sensor performance and
may cause malfunction!
