Pirani Standard Gauge<br />
Vacuum Gauges<br />
Pirani Standard Gauge<br />
PSG100-S, PSG101-S<br />
The Pirani Standard Gauges PSG100-S and PSG101-S are<br />
especially designed for easy integration into vacuum systems using<br />
Profibus DP or DeviceNetª fieldbus protocols. The gauges are<br />
equipped with a set point and for corrosive applications, a platinum<br />
filament version is available.<br />
Patent pending<br />
Advantages<br />
♦ Fieldbus interface (Profibus, DeviceNet) for easy integration into vacuum<br />
systems using network communications<br />
♦ For corrosive applications or high levels of water vapors the PSG101-S<br />
uses a platinum filament and a Al 2<br />
O 3<br />
ceramic feedthrough<br />
♦ Setpoint with adjustable threshold over a wide range<br />
♦ Mount in any position<br />
♦ Logarithmic analog output signal available<br />
♦ Sensor cell is easily replaced<br />
Typical Applications<br />
♦ Processes with corrosive gases (PSG101-S)<br />
♦ Fore vacuum pressure monitoring<br />
♦ Controlling of high vacuum ionization gauges<br />
♦ Safety circuits in vacuum systems<br />
♦ General vacuum measurement and control in the fine and rough<br />
vacuum range<br />
Fieldbus<br />
Fieldbus allows processes or applications the flexibility and control of<br />
network communications. It permits communication of exact digital<br />
information, independent control, maintenance and diagnostic routines<br />
for each connected instrument and simplifies your connection diagram.<br />
The measures of control include: monitoring of measurement values,<br />
automatic zero point adjustment of gauges, update operator of scheduled<br />
maintenance work, warning signals in case of instrument failure, and more.<br />
Profibus DP<br />
The central automation systems, e.g. PLC/PC or process control systems,<br />
communicate through a fast serial connection with decentralized<br />
instruments such as I/O, motors, valves and pressure transmitters. The<br />
exchange of data with the decentralized instruments takes place mostly in<br />
cycles. The basic functions of the Profibus DP Communication Profile also<br />
include acyclic communication services for parameter setting, controlling,<br />
monitoring, and alert functions of intelligent instruments.<br />
DeviceNet<br />
The DeviceNet interface supports polling, bit strobe and change of<br />
state/cyclic commands. Like with other DeviceNet instruments the user<br />
can monitor and control all available sensor functions.<br />
