1.High-low pressure control switch; 2.Usage:air-conditioning cooling system; 3.Order: 2000,000 pieces per year.
This type products are mainly used in high-low pressure protect control of air-conditioning cooling system,no matter for house-use,commercial-use,auto-mobile,and also fit for the other equipment.
When the pressure inside the system is over or below rated safe pressure ,the disc in sensor will start move instantly,and this works together with the connecting rod and push the switch connector to open or close.When pressure deduce or rise to rated reset point,the disc will reset accordingly,and the switch also auto reset.
The series technique are as follows:
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 |
