OPTIONS
7.1
RS485 Output
An RS485 interface is available as an option to the standard RS232.
Using RS485, the request commands and responses are identical to those stated in
Section 4.5.2, the RS485 serial link has the same protocol, see below:
9600 baud rate,
8 data bits,
1 stop bit,
No parity.
7.2
Remote Pressure Transducer
The standard S4000
Integrale
Dewpoint Meter is configured such that all pressure
sensitive parameters are calculated at 101.3 kPa (atmospheric pressure).
As an option, the instrument can be supplied with a pressure transducer to allow the
actual sample gas pressure to be monitored, and the PPM(V), PPM(W), g/m
3
and g/kg
parameters to be pressure compensated.
The standard pressure range is 0 to 50 psi absolute, i.e. at / around atmospheric
pressure. But particular pressure ranges may be supplied to order. Contact Kahn
Instruments’ Technical Sales Department for further information.
