BIMETALLIC THERMOSTATS
Euroswitch offers single-pole thermostats with bimetal disc and quick opening contact, available in various configurations. The cut-in temperature and differential may vary, depending on the specific application. Cut-in temperatures are controlled with the minimum electric load in the contact circuit.

Main applications:
temperature control in hydraulic systems, radiators, heat exchangers, lubrification system, automotive.
 
They come in three main types:
  • with NORMALLY OPEN (NO) (SPST) electrical contacts
  • with NORMALLY CLOSED (NC) (SPST) electrical contacts
  • with (SPDT) SWITCHING contacts

In the NORMALLY OPEN (NO) version (Fig. 1), the contact is open, i.e. there is no flow of current in the absence of temperature. When the temperature setting is reached, the electrical contact closes.

Figure 2 shows a thermostat with NORMALLY CLOSED (NC) contacts in the absence of temperature. We can see that the contacts are closed and the signal is present on the external contacts. When the temperature setting is reached, the electrical contact rises and interrupts the signal.

In the SWITCHING CONTACT (SPDT) versions (Fig. 3), the temperature of the fluid on the separating element causes a microswitch to switch over. Either NC or NO contacts, or both, can be used in this version.

Conditions of use
Suitability for the intended use must be verified according to the specific fluid and normal operating conditions.
