Temperature control systems
A temperature controller is always required to regulate Busse press tools. If no such controls are installed on your presses, they have to be retrofitted.
Analogue temperature control
For this method we offer a temperature control system with direct-reading remote thermometer. The thermostats have a setpoint value setting and a process value display in accordance with DIN 3340 and they are VDE-tested (Association of German Electrotechnical Engineers). All remote thermometers are fitted with a 3 m or 5m capillary line with a capillary anti-break device. The anti-break device increases the operational reliability of the control system and the heating plates. The temperature controllers can be supplied for the ranges 0 - 160°C, 0 - 200°C and 0 - 250°C. The number of remote thermometers depends on the number of heating plates to be controlled.
Digital temperature control
We recommend the use of microprocessor controllers if particularly accurate measuring results are called for or if the temperature is to be determined at several points on a heating plate. The compact iTron04 controllers are equipped with a switchable actual (process) and set value display. The values are measured by means of a PT-100 resistance thermometer. The measuring ranges are freely programmable.
iTron microprocessor controllers
The JUMO iTRON series of controllers comprises universal and freely programmable compact instruments for a variety of control tasks. It consists of five models with the bezel sizes 96mm x 96mm, 96mm x 48mm in portrait and landscape format, 48mm x 48mm, and 48mm x 24mm.
The controllers feature a clearly readable 7-segment display which, depending on the version, is 10 or 20 mm high, for process value and setpoint indication or for dialogues. Only three keys are needed for configuration. Parameter setting is arranged dynamically, and after two operation-free seconds the value is accepted automatically. Self-optimisation, which is provided as standard, establishes the optimum controller parameters by a key stroke. The basic version also includes a ramp function with adjustable gradients. A timer function has been integrated as an extra.
All controllers can be employed as single-setpoint controllers with a limit comparator, or as double-setpoint controllers. The linearisations of the usual transducers are stored. Protection is IP65 at the front and IP20 at the back. The electrical connection is by a plug-in connector with screw terminals. The inputs and outputs are shown in the block structure below.
