Eurotherm piccolo™ controllers offer precision PID control of temperature and other processes with many advanced features not normally found in this class of controllers.
Designed to offer outstanding performance in an affordable package providing a complete solution for a wide variety of applications, this range guarantees extremely easy access to
parameterization and operation in a high quality unit.
Despite their advanced features, the controllers are easy to use and apply and may be customized for ease of operation. Full autotune is provided.
High quality and high reliabilty
The piccolo controller is a high quality and high reliability
unit from a world leading manufacturer with global
support and service facilities. A 3 year warranty is pro-
vided as standard.
Ramp-soak timer and soft start
A ramp soak timer is provided for time based profiling
of temperature sequences. These can be used to
gradually vary the temperature in a control zone before
maintaining it at a defined level, and is typically used to
avoid the dangers of damage due to thermal shock.
Energy usage estimation
The piccolo controller allows estimation of energy
usage to provide basic data for evaluating energy
saving control strategies for continuous improve-
ment and Kaizen techniques.
Overshoot elimination
The Eurotherm unique cutback system ensures pre-
cise control to setpoint and when correctly tuned
inhibits temperature overshoot.

-
Plastic Processing Control
The precision PID controller is used to ensure
uniform heating of the material to avoid material
derogation, undue strain on the extruder
components and improve process reliability.
Can be used to consolidate functions and replace
several interconnected devices to chillers, including
an external timer. -
Incubators
-
Food and Beverage
The simple timer may be used to control
batch operations, e.g., food ovens, fryers
and sterilizers. -
Furnaces, Ovens & Kilns
Well adapted for firing ceramics and heat
treating complex parts. -
