One of the many products that JUMO will present is the new Quantrol controller series, made for simple applications. The devices are operated using four buttons on the front that have a defined pressure point. The universal analog input for RTD temperature probes, thermocouples, or current / voltage signals can be programmed by the user. The desired value, actual value, and all parameters are displayed on two seven-segment LED displays (red/green) to one or two decimal place(s). The values can be displayed in °C or °F. Up to five relay outputs with a switching capacity of 3 A / 230 V can be available. The number of relay outputs depends on the format. The switch position of the relays is displayed using yellow LEDs. These relays can be assigned different alarm functions. An analog output from 0 to 10 V or 0(4) to 20 mA can be used to control valves or SCR power controllers. Using the binary input, the Quantrol device settings and operation can be gradually locked, a ramp or timer can be activated, or self-optimization can be initiated.

The new Quantrol series is available in the three DIN formats 48 x 48 mm2, 48 x 96 mm2, and 96 x 96 mm2. The device can be connected to host systems or devices using the RS485 serial interface. Instead of operating the device from the front, the user can also program the controller using a setup program and USB interface. The controller does not need to be connected to another voltage supply during programming because the power comes from a USB interface. The Quantrol series, like all JUMO controllers, is also equipped with reliable JUMO self-optimization. This saves on costly manual settings and subsequently on time and money. The supply voltage may be between AC 110 to 240 V or AC/DC 20 to 30 V. All devices have UL (cUL) approval.

Process control
The JUMO DICON touch universal process controller with touchscreen was designed the operation and control of processes. Consistent controller results are required to ensure the high quality of a product. Product manufacturers make a solid choice with the DICON touch, the two-channel universal process and program controller from JUMO. Both control channels use the tried-and-tested JUMO control algorithm with two possible optimization options to suit the relevant requirement and process. These enable a simple, highly-accurate, and time-saving startup. As a result, this process and program controller handles even multi-zone control, cascade control, or other complex/interlinked control tasks with ease. Here, the control processes can be visualized on the vibrant TFT color graphics display. The touchscreen ensures that operation is comfortable and intuitive, which in turn facilitates the startup and system management.

Pressure Transmitter
The new Wtrans p wireless pressure transmitter is quick and easy to mount and install. Whether in stationary plants or in mobile systems, in hard-to-access areas, or even in rotating components: the device is supposed to reduce the effort required for installation and assembly - both in the reconception of a plant and when retrofitting an existing measuring location. In addition, the device saves cables and enables pressure measurements, especially where a cable extension would be impossible or would require too much technical effort.

The pressure transmitter with protection type IP 67 records relative and absolute pressures from 250 mbar to 600 bar. Within a range of up to 300 m the measured values are then sent to the receiver. Transmissions are made via the 868.4 MHz radio frequency of the license-free ISM band. A value in the range from 500 ms to 3600 s can be selected as the transmission interval. The battery in the transmitter lasts for up to one year depending on the transmission interval setting.
