JUMO AQUIS 500 - New transmitter/controller series for analytical measurement

This new compact design still features all the most useful options, and is so simple to use its “child’s play”:

The new JUMO Aquis 500 can be used for the measurement and control of the most widely used liquid analysis parameters.

Available are options for pH/Redox, the JUMO AQUIS 500 pH, and electrolytic conductivity measurements using 2- and 4-electrode methods the JUMO AQUIS 500 CR. The series is completed by two additional versions with connection options for inductive conductivity probes the JUMO AQUIS 500 Ci or for specific process variables the JUMO AQUIS 500 AS (e.g. for dissolved oxygen, free chlorine etc.). Each instrument is also fitted with a temperature measurement input for Pt100/Pt1000, for temperature compensation or monitoring.

The JUMO AQUIS 500 series can be used wherever a compact on-site transmitter/controller is required. Typical areas of application for the JUMO AQUIS 500 are plant installations in water and wastewater engineering and treatment, desalination, pharmaceuticals and food, electroplating/cleaning systems in the metalworking industry and semiconductor fabrication, ion-exchange plants, power stations and biological engineering. Since the front of the AQUIS 500 contains the entire electronics, it can also be used in the classic switchgear cabinet construction (built into the cabinet door).

The combination of background-lit graphics display and plain- text messages means that operation can almost be carried out without an operating manual. A ‘commissioning assistant’ facilitates the first programming of the instrument for the intended measurement task. The ‘assistant’ guides the user through the most important menus – programming errors are practically a thing of the past. Several operator languages have been integrated or can be loaded through an optional set-up program. A generous membrane keypad makes it easier to navigate through the plain-text menus.

The measurements for the first principle variable and the temperature can be displayed either numerically or as a bar graph. A trend indicator provides information on the rate of alteration of the present measurement. This helps the user in, for instance, the evaluation of settling processes in systems.

The instruments feature a compact, field-proven plastic housing with IP67 protection. The front section is detachable and contains the entire electronics, so that the transmitter/controller can be mounted in a control panel cutout. A valve with a diffusion-open membrane prevents condensation.

All versions can be fitted with up to two electrically isolated analogue outputs 0(4) – 20mA or 0(2) – 10V as process value or control outputs. The type of output and the scaling are freely programmable.

Two additional outputs with changeover relays can be fitted. The relays enable a simple limit monitoring as well as a more demanding PID control loop function. The control of the typical actuators used in analytical measurement (e.g. valves, dosing pumps) is implemented without any problem, using pulse frequency or pulse width control.

Three power supply versions permit operation with typical supply voltages: 12V DC, 20 – 53V AC/DC and 110 – 240V AC.

An optional PC set-up program enables comfortable configuration of the instruments and easy system documentation.

The JUMO AQUIS 500 pH and JUMO AQUIS 500 CR versions of these instruments will be available in the 4th quarter of 2006. The Ci and AS versions will follow at the start of 2007.

The instruments were presented for the first time at the international ACHEMA 2006 Trade Fair in Frankfurt and will be introduced to the UK at Water and Waste Monitoring Conference and Exhibition (WWEM) at Telford International Centre 1st & 2nd November on JUMO Instrument Co. Ltd Stand No. 23.
