The Model PFS-1 Precision failsafe is a simple screwdriver adjustable unit designed for
applications where the failsafe setting does not get adjusted often.
Standard temperature range is -100°C to +200°C. Other ranges available.
This is the perfect unit for production environments
where settings are
long term and operator access to the failsafe is not desired.
When the high or low limit set with the failsafe is exceeded, the main heating
and
cooling power relay is disengaged by the failsafe and the controller is notified of the
event.
