 Surface-Mounting Thermostat ATHs-2U with Z- Pocket 
  Temperature Range: +50°C to +300°C
   ATHs-2U with Z-Pocket "monitors" the adjusted Temperature, shuts down the  
   system when the adjusted temperature is exceeded and after running a
   hysteresis loop the system turns up independently.
   
 
   Technical Description
   
   
   Operation
   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 mircoswitch. 
   The temperature is only sensed by the 
   temperature sensor.

   Switching Operation
   When the actual temperature exceeds 
   limit temperature the microswitch 
   opens or closes the electric ciruit by
   the sensor system. 
   After the temperature has returned down to
   the hysteresis loop´s limit,
   the microswitch sets the
   circuit to beginning status.

   Switch Element
   cased microswitch with 
   change over contact.

   Application Area
   The ATHs-2U with Z-Pocket
   surface mounting thermostat is 
   used as a safety temperature limiter in 
   laboratory and climatic cabinets, in 
   furnace applications and
   in mechanical apparatus
   applications per DIN 3440 standard.

   Note:
   per DIN 57100 part 420 VDE0100 
   are two temerature momitoring systems, 
   independent from each other, forcing required. 
   One of them has to be performed as 
   safety temperature limiter.
