Dwyer Instruments' TSF-DF Thermocouple Limit Alarm is designed to be a UL recognized temperature limit control
Dwyer Instruments' TSF-DF Thermocouple Limit Alarm is designed to be a UL recognized temperature limit control used to give a visual alarm and switch output when a process has reached a high temperature limit. Applications are built to include deep fryers, kitchen hoods, and other food service and process equipment where a local alarm is needed to let the operator know of potentially dangerous conditions. Once the temperature has returned to normal, non-alarm condition the TSF-DF is designed to either automatically reset or require a manual reset from the user. To prevent the user from tampering with the settings on this alarm, the buttons on the face of the control are constructed to only be used to reset the alarm condition. All programming is made to be done through a master control and a program configuration key.
