The Perfect Fit for Simple Applications
Uncompromising process performance in a cost effective format
Easy to integrate and commission, yet highly cost effective, the EFit power controller provides no compromise control for resistive and infrared heating elements. Ideal for all heating applications and fully compliant to international quality, immunity, and emissions standards, Efit achieves outstanding stable, precise control in the most demanding industrial environments, even when cabinet space is at a premium.
The perfect fit for simple heating applications
Some Industrial processes such as heat treatment require precise temperatures in order to comply with regulations and it is imperative that the workpiece temperature is kept within specific limits. This can be difficult to achieve in industrial plants where the operation of large machinery can cause fluctuations in the voltage supply. In the case of resistive heaters a variation of 10% in the supply voltage will generate a 20% variation in the power to the load, resulting in undesirable temperature fluctuations. EFit contains built in compensation that continues to apply stable power with better than ±2% linearity at the boundaries of the load, even during fluctuations in the supply. The result is a reliable, repeatable heating process and high quality end products compliant to demanding heat treatment standards.

Temperature Controllers:
Process Application Control
Whether it is Open-Loop or Closed-Loop Control, a good Control System is critical for long heater life.*
Here we demonstrate a Closed-Loop (Feedback) Control Set-up ~
Generally considered the optimal method, a closed-loop heater control system uses a power controller, temperature controller, and thermocouple to provide a constant output temperature, regardless of changes in airflow.
P116 Dimensions
General views of the controllers are shown below together with overall dimensions.
P116 Rear Terminals
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.
