Digital Controllers

RZ series

■Temperature and level management of chemical solution

In the etching and cleaning processes of semiconductor manufacturing, highly corrosive chemical solution is used. To measure temperature and level of such chemical solution, highly corrosive resistant sensors are used.

RB series

■Temperature control of incubators

Temperature set point can be switched over using external contact input according to the object to be warmed.

SA200

■Temperature control of incubators

Temperature set point can be switched over using external contact input according to the object to be warmed.

FZ series

■Rapid Thermal Process (RTP) like Lamp annealing

When temperature rises rapidly, a controller with fast sampling and an output device with fast response need to be used.

■Cascade temperature control in diffusion furnace

If there is a large time lag between the controlled object and the heat source, the cascade control could be suitable. The control output from the primary controller (Master) is input into the secondary controller (Slave). The secondary controller conducts temperature control of the heat source while correcting the temperature setpoint with the control output from the primary controller. Cascade control can be achieved with a single FZ400/FZ900.

■Melt pressure control of extruders

RPM of main motor is controlled to maintain constant melt pressure (discharge rate).

■Highly accurate temperature control of T-die

Enables highly accurate temperature control using power controllers. Use of Automatic temperature rise function* of SRZ enables a uniform temperature rise in the T-die. * Function to increase the temperature of all zones at the same rate.

■Temperature control with suppression of external disturbance when ingredients are put in

Temperature rapidly goes down when ingredients are put in the cooking machine. To minimize this temperature change, appropriate control of heater is necessary.

■Optimum control of parching machine using control with PV select

Temperature of the controlled object is automatically switched (from in-the-pot temperature to foodstuff temperature)

■Cascade temperature control of autoclave

The temperature of the slave (heat source) is controlled to maintain a proper temperature of the master (sterilized target).

■Control with PV select in High temperature firing furnace application

Input 1 and Input 2 are automatically switched at the preset temperature. For example, a thermocouple is used in the lower temperature range, and a radiation thermometer is used in the higher temperature range, which are switched between each other at the preset point.

FB series

■Ratio temperature control of continuous furnace (Link operation)

Temperature program control of each zone is conducted with the preset ratio.

HA930

■Melt pressure control of extruders

RPM of main motor is controlled to maintain constant melt pressure (discharge rate).
