At the heart of the 12 Series is a Belleville spring assembly. The spring is asmall conicalwasher that transfersmotion to a hermetically sealed 1 or 5 ampmicroswitch. Its ‘snap-action’ provides fast, positive contact transfer.

UnitedElectricControlsCompany recommendscareful considerationof the following factorswhen specifying and installingUEpressureand temperature units. Before installing a unit, the InstallationandMaintenance instructions providedwith unitmust be read andunderstood.
• Toavoiddamagingunit,proofpressureandmaximumtemperaturelimits stated in literature and on nameplates must never beexceeded,evenbysurgesinthesystem.Operationoftheunituptomaximumpressureortemperatureisacceptableonalimitedbasis(e.g.,start-up,testing)butcontinuousoperationmustberestrictedtothedesignatedadjustablerange.Excessivecyclingatmaximumpressureortemperaturelimitscouldreducesensorlife.
• A back-up unit is necessary for applicationswhere damage toa primary unit could endanger life, limbor property.A high orlowlimitswitchisnecessaryforapplicationswhereadangerousrunawayconditioncouldresult.

• Install unit where shock, vibration and ambient temperaturefluctuations will not damage unit or affect operation. Whenapplicable, orient unit so that moisture does not enter theenclosure via the electrical connection.When appropriate, thisentrypointshouldbesealedtopreventmoistureentry.
• Monitoroperationtoobservewarningsignsofpossibledamageto unit, such as drift in set point or faulty display. Check unitimmediately.
• Preventativemaintenance and periodic testing is necessary forcritical applicationswhere damage could endanger property orpersonnel.
