  This product is different from the conventional pressure switch：
It’s    combined   electric  contact   pressure gauge combines   the
advantages of accurate readings, through photovoltaic technology
control the  installed  equipments  on-off  freely.     Product   design
components  including:  a  stable  and  reliable  electronic   circuits
(Figure 1), high-performance electronic relays ,  sensitive   precise
photoelectric sensor, electric contact pressure gauge plate,   high-
strength plastic sheet (or metal sheet).
      To comparing with the traditional domestic and foreign products,
we have the following advantages:
1. Arbitrarily set to start and turn off the value of stress value.
2. Precise control makes no problem in continued repetition on-off.
3. Working    stress   shows   on   dial   makes    observation    more
convenient.
4. Long working life, stable performance.
5. The minimum pressure can adjustable to zero pressure at start,
control more convenient;
6. Free from pressure limited ,0-0.6Mpa ,0-1Mpa,0-5Mpa ,0-50Mpa,
or higher;
7. Free from working condition limited  ,   it can work in any places
 there is pressure.
8. Don’t need to install the pressure tank.
