Control Sensor
Proper placement of the sensor can eliminate many problems in the operation of the system. The probe should be
placed so that it can detect any temperature change with little thermal lag. In a process that requires fairly
constant heat output, the probe should be close to the heater. In processes where heat demand is variable, the
probe should be close to the work area. Some experimenting with probe location can be tried to provide optimum
results.
