 Surface-mounting Thermostat AMHs-2-80U 
  Temperature Range: +10°C to +55°C 
   The Double Thermostat (safety temperature limiter and temperatur monitor) for many 
   applications. The AMHs-2-80U works as safety temperature limiter with manual reset 
   and as temperature monitor with automatic reset. Complies with EN-VDE requirements.
   Technical Description
   The operation of the 
   surfacemounting thermostat relies 
   upon phenomenon of liqudia expansion. 
   The volume of a liquid filled 
   sensor system(consisting of sensor,
   capillary tubing and membrane)varies with 
   varying temperatures. The resulting 
   membrane displacement actuates the
   The temperature is only sensed by the 
   temperature sensor.

   Switching Operation
   When the actual temperature exceeds 
   limit temperature the mircoswitch opens or 
   closes the electric ciruit by the 
   sensor system.
   Safety temperature limiter with Change over 
   When the limit temperature is exceeded, 
   the electric circuit is opened (or closed) 
   and the microswitch is mechanically locked.
   After the temperature has returned down to 
   the set limit the microswitch can be 
   unlocked manually, only.

  Temperature Monitor with Automatic Reset
   After the temperature has returned 
   down to the hysteresis loop´s limit, the
   mirco-switch sets the circuit to 
   beginning status.

   Duoble Thermostat
   The AMHs 2-80U surface mounting thermostat
   is used as a double thermostate (safety temperature 
   limiter and temperature monitor) in laboratory and 
   climatic cabinets, in furnace applications, and 
   in mechanical and apparatus applications 
   per DIN 3340 standard. The temperature monitor with
