The large, 5-digit display provides a clear and unambiguous indication of the process value. A four-line message centre provides custom or standard views of important information to the user, while vertical and horizontal bar graphs provide visual indication of the process at a glance.
OEM security enables a user to protect their intellectual property by preventing unauthorized cloning of configuration.
Dual Loop
Two independent PID loops make the 3500 ideal for interactive processes such as those found in carburizing furnaces, environmental chambers and autoclaves. The loops may also be ‘soft’ wired together in creative ways to create cascade, ratio or other intelligent control strategies.
Setpoint Programmer
Heat treatment and other processes often require the ability to change setpoints with time. The dual loop 3500 has two programmers which can be configured as synchronized or independent programs. 50 programs with up to two channels can be stored with a total of 500 segments.
Input/Output Flexibility
A range of plug-in I/O modules caters for individual application requirements minimising stock and spares holding. A total of sixteen module types, including relay, logic, triac and analogue, are available to fit into either three slots on 3508 or six slots on 3504.
Carbon Potential
The 3500 calculates carbon potential from measuring both the oxygen concentration and temperature of a furnace using a zirconia probe. This enables a dual loop 3500 to be used to control both carbon potential and temperature in an atmosphere controlled furnace.
