PAA-22PS是一种紧凑型可编程压力开关，同时具有模拟量变送器的输出信号0.5-5V，他可以通过模拟量信号持续的监视一个过程，开关功能可被用在达到预设的压力水平时的报警或延迟控制。
Pressure Switch PA-22 PS
User selected Switching Points and Functions
The PA-22 PS is a compact programmable pressure switch and pressure transmitter. It offers continuous analog 0,5…4,5 V signal for process monitoring and switch functions to activate alarms or control relays at predetermined pressure levels.
The PA-22PS provides two independent switches for hi/lo control functions. These solid state
switches are not subject to wear and can be factory programmed in either PNP or NPN outputs. The optional DV-22 PP programmer (external supply) allows the user to easily change settings. This programmer can also be linked to a laptop/PC for use with Keller's "Pressure Switch Console" software. The following characteristics can be programmed either at the factory, or by the User via the DV-22 PP:
• Switching thresholds
• Hysteresis / window function
• Normally open / normally closed
• Switching delay |
| Pressure Ranges abs. | 4…400 bar |
| Error Band (0…80 °C) | 2 %FS |
| Operating Temperature | -40…125 °C |
