Alarm
Condition or control function that indicates when the process is above or
below set-up point.
Bandwidth
Symmetrical zone around the setpoint where a proportional control takes
place.
Cold joint compensation
Device that prevents ambient temperature changes from affecting the
cold joint of a thermocouple.
Control algorithm
Method used by the control device to bring the system’s temperature
back to the setpoint. ON-OFF,
Proportional and PID are the most common algorithms.
Dead zone
1 – For graphic recorders: minimum change of input signals necessary to
2 – For temperature controllers (in °C): temperature zone where heating is
Derivative action (D)
Control function that measures the speed at which the system’s
temperature increases or decreases, leading to an accelerated mode
compensation control. This mode avoids overshoot of setpoint during
system set-up and disturbance.
Deviation
Difference between the measurement value and the set-up point value of
the setpoint.
Deviation alarm
Deviation value that follows the setpoint. If the set-up point is 350 °C and
the deviation alarm value is +20 °C, the alarm value is 350 °C plus 20 °C,
in other words 370 °C.
Droop
Difference in temperature between set-up point and the place at which
the system’s temperature stabilises. Can be corrected by manual or
automatic adjustment.
Fuzzy logic
Artificial intelligence technique that enables control decisions to be made
based on approximate or incomplete information.
Fuzzy logic is a decision-making function likely to prevent an initial
overshoot or a deviation from the set-up point.
Hysteresis
Change in temperature necessary to change the output power from on
to off on an ON-OFF controller.
Integral action (I)
Integral function of a control that automatically compensates the
difference between the set-up point and the process’s actual
temperature.
A signal moves the proportional band upwards or downwards to correct
the displacement error.

interrupted during temperature increase and reactivated when
temperature decreases. Zone in which no heating occurs (or no cooling
for hot-cold action).
Glossary of temperature control terms
Linearity
Difference between an instrument’s response and a straight line.
ON-OFF action
Controller whose required power is either 0 % or 100 %.
Process alarm
Fixed alarm value or independent secondary set-up point of the primary
set-up point. If one of the process’s values exceeds this value, an alarm
condition is stored.
Proportional action (P)
Once the operating temperature has almost reached the set-up point and
enters into the proportional band, the output power is requested and
turned off according to a predefined cycle. The current change on the
load reduces the heat power, thus avoiding temperature overshoot.
Proportional band
Temperature band expressed in degrees within which this function
operates.
Proportional-integral-derivative action (PID)
Triple action temperature controller: proportional, integral (automatic reset)
and derivative (speed).
Ramp
Programmed increase or decrease in temperature that evolves at
constant speed.
Range
Zone between two limits in which a measurement or setpoint action takes
place. Normally expressed in upper and lower limit values.
Rejection of common mode
An instrument’s capacity to cancel the presence of parasitic voltage
between the input terminals in relation to earth potential. Expressed in dB
(decibels).
Rejection in series mode
An instrument’s capacity to cancel the presence of parasitic voltage,
usually 50 or 60 Hz, between its input terminals.
Resolution
Difference between two changes in temperature that introduces a
change in control power. May be expressed in temperature or in
percentage of control scale.
Retransmission output
Analogue power to the scale of the process or the set-up point value.
RS485 output signal
Serial communication port multipoint interface standard.
Connection of a digital control to a PC, mainframe computer or printer.
Scale
Difference between the upper and lower limits of a range expressed in
the same unit.
Self-adjustment
Control used to calculate optimum PID parameters with integrated
algorithm software in order to avoid manual adjustment.
Sensor failure safety
Safety function that ensures power is cut off if a thermocouple fails.
Setpoint
Setpoint to obtain or maintain a temperature.
Scale
Difference between the upper and lower limits of a range expressed in
the same unit.
