Smarty II NC

Thermostat

Tmax 250°C / Imax 16A / short reaction time / orientation independent mounting / temperature resistant ceramic housing / standard terminals

Properly installed, the temperature controller type 161 771 may be used wherever a fixed temperature needs to be controlled. This thermostat is designed to obtain a differential of approx. 10 - 25 K.

It can be  supplied with contacts ”normally closed“ (161 771) and "normally open" (161 772).

A stamped bimetal disc is used as temperature sensing element. The disc is placed in direct contact with the mounting plate therefore reacting quickly to temperature change. Upon reaching the preset temperature  the bimetal disc provokes the opening (or the closing) of the electrical circuits. After the cooling phase, the disc snaps back to its original position thereby closing (or opening) the circuit again.

Applications

Properly installed, the temperature controller type 161 771 may be used wherever a fixed temperature needs to be controlled. This thermostat is designed to obtain a differential of approx. 10 - 25 K.

It can be supplied with contacts ”normally closed“ (161 771) and "normally open" (161 772).
 

Structure and mode of operation

A stamped bimetal disc is used as temperature sensing element. The disc is placed in direct contact with the mounting plate therefore reacting quickly to temperature change. Upon reaching the preset temperature  the bimetal disc provokes the opening (or the closing) of the electrical circuits. After the cooling phase, the disc snaps back to its original position thereby closing (or opening) the circuit again.

Advantages

  • easy mounting
  • for switching temperatures up to 250°C max.
  • high current carrying capacity
  • as a variant also suitable for low currents (<1A) and voltages
  • high contact pressure, low contact resistance
  • rapid heat transfer in all mounting positions
  • fast response time, suitable for high-performance and low-mass heating elements
  • robust ceramic-housing with separated switching chamber
  • stable switching temperature also under different current loads
  • high electric strength between the contacts - even after many switching cycles
  • high insolation resistance to base plate
