Pressure switches with integral pressure gauge ДЕМ-105М1-РАСКО

Pressure switches with integral pressure gauge ДЕМ-105М1-РАСКО (hereinafter – devices) are intended for signaling and relay control of the medium pressure by opening or closing electric contacts.

Scope of application:

- ventilation, air conditioning and cold supply systems;

- pump, compressor and turbine machine building;

- local automation systems at heat, water and power supply facilities.

Controlled medium is water, air, freons, oils and other liquids and gas, with a maximum viscosity of 0.8 Pa_˙s, nonaggressive to the used structural materials.

Devices are fit for operation under conditions established for version ОМ5 as per GOST 15150, bur for operation within the temperature range from minus 20 to plus 60^oC.

The devices are fitted with an electrical connector as per EN 175301-803 for coupling with external cable. 

The devices are supplied with coupling thread М12х1.5, G1/4 and G1/2.

Guarantee period of storage is 18 months since the date of manufacture.

Guarantee service life is 12 months since the date of commissioning within the guarantee period of storage. – page 26 of the Catalog
