|The thermoswitch like AD-155M is applied in devices to control of temperature and the alarm system. Thermoswitches are made performed by UHL and have to be operated in the closed heated rooms with artificially adjustable climatic conditions (category of placement 4).
Atmospheric pressure is from 101320 to 5460 Pas (from 750 to 41 mm of a mercury column)
Relative humidity of air of 80% at a temperature of 25 °C
The Wednesday which is surrounding a thermoswitch, explosion-proof, not containing aggressive gases, liquid, dust in the concentration breaking work of a removyklyuchatel
Lack of direct influence of solar radiation
Vibration in the range of frequencies 20-80gts at acceleration to 39.2m/with ² (4g)
Position in space - any.
Thermoswitches, depending on a type of contact are made in the following executions:
And - with the disconnecting contact at temperature increase of the air which is flowing round a thermoswitch;
B - with the closing contact at temperature increase of the air which is flowing round a thermoswitch
