This type product is special used on the air-conditioning cooling system,when the water pressure is too low,it can control the water lever, and the machine will stop.
The series pressure controller technique is as following:
Ordinal number | Name | The technique request |
1 | The pressure value sets the scope | 3-667PSl / 0.02-4.6Mpa |
2 | The pressure value business trip scope | 1.45-14.5PSl / 0.01-0.1Mpa |
3 | Touch some form | NC (H) NO (L) |
4 | Contact capacity | AC240V 3A AC120V 6A |
5 | Contact resistance | « 50mΩ |
6 | Insulate the electric resistance | » 100mΩ Connect the line carries with a » 100mΩ |
7 | The anti-electricity strength | The AC1500V last the 1 min clock and did not broke through and gleam |
8 | Biggest blow up the pressure | At the « 5000PSl of («34.5Mpa) blows up the pressure under the 1min clock did not burst the phenomenon |
9 | Air tightness | The 4.8Mpa/ 1 min no leakage |
10 | Adapt the temperature | The environment temperature -30 ~ +80°C Lie the quality temperature -50 ~ +120°C |
