Press releases Process Technology

User-friendliness, a large range of application possibilities and highly accurate data are the decisive criteria for the purchase of such a device. These are exactly the points Kübler attaches great importance to. With success: the Codix Process Displays set new standards in this branch. The new generation of powerful and particularly fast Process Controllers for standard signals, temperature and strain gauges, with the practical Quick-start Guide, is now also available with an analogue output for the DC supply version.

Codix 564, Temperature Controller

This device receives mV signals from many different temperature sensors (thermocouples) or resistance values (RTDs, PT100, PTC, NTC etc.), as well as direct mV and resistance input signals, which can be scaled and displayed on the 6-digit display. The device can also store and display upon request the minimum and maximum measured values. The analogue output converts one of these measured values into 0/4-20mA or 0/2-10VDC standard signals and passes these scaled values on to a higher-level PLC, to the PD or to the curve tracer. In addition, the controller can control a plant independently by means of the two relay outputs, thanks to a 2-point regulation.

Codix 565 Standard Signal Controller

This device receives standard signals from many different sensors such as flow, speed, filling level, stroke, distance, pressure, humidity, dew point etc., which can be scaled and displayed on the 6-digit display. Also this device can store and display upon request the minimum and maximum measured values. An additional totaliser totalises the measured values on a time basis to display the quantities over time. The analogue output converts one of these measured values into another standard signal and passes the scaled value on to a higher-level PLC, PC or curve tracer. This controller also allows controlling a plant by means of the two relay outputs, thanks to a 2-point regulation.

Codix 566 Strain Gauge Controller

This device measures the pressure or the weight, which can be scaled and displayed on the 6-digit display, using a strain gauge input. The minimum and maximum measured values can be stored and displayed upon request. The totaliser totalises the measured values upon a key press or the activation of a control input, to display the total quantities. The analogue output converts one of the measured values into a standard signal and passes the scaled value on to a higher-level system. A control using the 2-point regulation is also possible with this device.

With its new Process Controller Type 573 Kübler is introducing a multi-faceted device for use in the process engineering industry. The device has two analogue inputs and an analogue output or two optocoupler outputs and can thus be used both in single channel mode as well as in dual channel. In dual channel mode, all arithmetic operations are available for displaying sum total, difference, ratio or the product. Inputs and outputs can be scaled separately.

The Type 573 Process Controller can be used as a simple process signal converter, process controller (ON/OFF controller) or for complex measuring tasks, where the relationship between two values, one to the other, must be monitored, calculated or further processed in a higher-level controller. Application areas include for example the monitoring of mixing ratios, the display of flow rate and with material stretching. Other areas include the monitoring of synchronous operation and display of individual speeds, as well as level monitoring and adjustment and the display of inflow and outflow.
When input signals are fluctuating strongly, a reliable average measurement can be made over 2 to 16 measuring cycles. The user can also linearize the display with up to 16 control points, either via the key-pad or via the Teach-In function.
The simple menu-driven programming is carried out using just two keys as well as a separate Tare or Teach-In key. With the tare function the unit can be set to 0 for any input voltage.

The measured values of inputs A and B are associated mathematically. Thus the result can also be multiplied, divided or added to an offset value, in order to obtain the desired display value. The user can consequently obtain up to three display values with just one device: Display A, Display B and a display based on the calculation of A and B.

The analogue output ranges from 0/4 ... 20 mA, +/-10 V or 0 ... 10 V. Two fast PNP switching outputs (50 ms at a measuring rate of 25 ms per channel alternating) offer switching hysteresis plus step or tracking presets.
The two separate freely-scalable analogue inputs range from +/-10 V, 0 ...10 V and 0/4... 20 mA, with a resolution of 14 bit.
To top this off, the new Process Controller Type 573 can be run from either an AC or DC supply voltage.
