PS41 系列壓力開關
經(jīng)濟的小型壓力開關
特性...
- 3.5到100psi (0.24到7bar
概述/設計原則:
PS41系列小型壓力開關設計用于空間和/或價格敏感的苛刻場合。采用活塞/隔膜設計，集活塞技術的耐高壓和隔膜的靈敏度于一身。采用內(nèi)六角頭螺絲，即可實現(xiàn)現(xiàn)場調節(jié)，又可防止人為誤動.

| Pressure Range Code | Pressure Range | Repeatability | Average Deadband* |
| 10 | 3.5 - 8 psi (0.24 bar - 0.55 bar) | ± 0.35 psi (0.024 bar) + 2% of setting | 1.50 psi (0.14 bar) + 7% of setting |
| 20 | 7 - 30 psi ( 0.48 bar - 2.07 bar) | ± 0.8 psi (0.055 bar) + 2% of setting | 3 psi (0.21 bar) + 8% of setting |
| 30 | 25 - 100 psi (1.7 - 6.9 bar) | ± 2.0 psi (0.138 bar) + 2% of setting | 5 psig (0.28 bar) + 10% of setting |
* These numbers are for the standard microswitch. With either the -SP or 10A option, the values are typically 20% greater than those listed. With the -RD option, the values will be typically 25% less than those listed. In certain applications, deadbａnd can be tailored and controlled to customer specifications. Consult factory for details.
