Pressure switch sensor DEM-102-1-01A-2
PRESSURE SWITCHES DEM 102
Designed for control and two-position regulation of pressure of liquid and gaseous media in refrigeration units used on ships, railway and motor transport, as well as in stationary installations and other systems and devices. & nbsp;
Controlled media: freons, air, oils and other non-aggressive media ... For DEM102-1-01A, DEM102-2-05A devices, ammonia can be a controlled environment. & Nbsp;
They are distinguished by high resistance to dynamic loads (vibration, shock, shaking, tilting), protection from dust, water and other environmental factors environment. & nbsp;
Degree of protection of the device case DEM 102-1 & minus; 01 & minus; 1 & nbsp; С, DEM102-1-02-1С, DEM102-2-02-1С & nbsp; & mdash; IP67, other devices & nbsp; & mdash; IP64.
