Temperature Controller "Smarty II" (normally open)
Properly installed, the temperature controller type 161 772 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.
- easy mounting
- high contact pressure and low contact resistance
- orientation-independent rapid heat transfer
- fast response time, suitable for high performance and low-mass heating elements
- robust ceramic-housing with separated switching chamber
- high electric strength even after many switching cycles
- stable switching temperature even with different current load
