Fenwal Mechanical Temperature Switches ~ THERMOSWITCHES-----> Shop online for Fenwal Thermoswitches <-----FENWAL Series 17000 and 18000 Probe style THERMOSWITCHES THERMOSWITCH® Temperature Controllers are tubular devices featuring an outer shell made of high-expanding metal and internal struts made of low-expanding metal, with a pair of electrical contacts between them. When the temperature of the media being measured changes, a corresponding change in the spacing of the contacts provides instant on/off control with a small differential, resulting in +1ºF precision, depending upon the application. Fenwal Thermo Switch Model Numbers : 17000-0, 17021-0, 17002-0, 17023-0, 17100-0, 17121-0, 17102-0, 17123-0, 17200-0, 17221-0, 17202-0, 17223-0, 17300-0, 17321-0, 17302-0, 17323-0, 17800-0, 17821-0, 17802-0, 17823-0 18000-0, 18021-0, 18002-0, 18023-0, 18002-21, 18023-7 (Click on the part numbers above to BUY) Series Features: Specifications: Agency Approvals: Applications:
Fenwal series 30000 Surface Mount THERMOSWITCHES Fenwal Thermo Switch Model Numbers: 30000-0, 30000-48, 30002-0 (Click on the part numbers above to BUY) Based on the differential expansion of metals principle, an increase in temperature causes the stainless steel outer case of the Surface Mounting THERMOSWITCH® controller to expand at a greater rate than the internal bridge assembly. Because the case is in direct contact with the heated surface, a temperature change is sensed almost instantaneously.
