Sensor of the dry course of PS 7C
The sensor of the dry course - the device which is installed in system of water supply for automatic switching off of all types of pumps at absence or an insufficient amount of water in wells, special stations, wells and other tanks.
The reasons of sharp change of water level in tanks with water:
- Incorrectly chosen pump for water pumping out. Its power too big for that volume of water which is available in the well, a well, the station, etc.
- Blockage or unsealing of system for water inflow.
- Weak pressure or its total absence.
There are several types of sensors of the dry course which have different type of the device and the mechanism of action, but the end result at all one. The pump ceases to work in the absence of necessary water level. To find out what of them the best were sociological survey among consumers is conducted. As a result sensors which are built in just before pressure relay were recognized as the most effective. In common they give to 100% protection of operation of the pump and prolong the term of its service.
The principle of its work is that in the absence of the necessary pressure from water supply, the sensor works and gives a signal to the pump for completion of work. As a result water flow in the relay of pressure which also works on "the dry course" stops. It turns out that one insures another, doing thereby system of water supply and the pump more protected from unforeseen circumstances.
It is also worth noting that the special equipment for its installation is not required. There is a sensor in free access and therefore to find it on counters of shop rather easily. Skilled plumbers also give the preference to sensors of dry course of this kind.
Any even if at first sight the most perfect, the system has not completions, and the sensor of a dry bottom not an exception.
Shortcomings of the sensor of the dry course of the pump:
- Creates an obstacle for water flow therefore the pressure of water decreases
- At its installation in front of pressure sensor relay, getting littered, does not allow water to arrive on it and by that water ceases to circulate on system of water supply. In it a case the pump does not receive a signal of termination of work and as a result burns down from lack of water in the well or other source of water.
- Demands regular technical inspection in order that it did not get littered.
Despite all shortcomings, the sensor of the dry course remains to one of effective methods of protection against sharp change of water level in tanks. The sensor of the dry course of PS 7C from the producer Belamos one of the best in the category. The firm producer tried to consider all shortcomings which happen at devices of this sort, and eliminated them. Power which are not exceeded by 1, 5 kW approaches any kinds of the pump. Works from tension 220B.
It is mounted directly over the relay of pressure and has a universal carving which approaches all pumps of this producer. The connecting size of a pipe carving is equal to G?. Water temperature should not be above 55 degrees above zero.
The sensor understands easily and cleaned. It costs rather not much and therefore if you have no special desire to clean it, then it is possible just to replace new. It is important to remember that once a month at average pollution of water it is obligatory to do it once a month. At installation of additional filters for water the sensor practically does not demand either cleaning, or replacement. Recommend to use it together with the relay of pressure and the pump of one firm.
Easily is established and does not demand at the same time special skills and knowledge. All interesting questions can be asked specialists of the company on the official site.
If there is an opportunity to somehow secure operation of the pump against unforeseen circumstances, then it is better to use an easy, economic way. Purchase of the new pump will be much more more expensive, than the sensor of the dry course. It is possible to buy the sensor of the dry course in retail network of retail trade from official dealers or on the official site of the company. Anyway it is favorable an investment which guarantees safe work of all system of water supply.
If you need the PS 7C sensor (protection against the "dry" course) which price very moderate, then you got precisely to the address. We will help you to pick up suitable model therefore address for any recommendations.
