Indicators, Hazardous Area

The 830 X loop-powered digital indicators are universally applicable. The range (either 0 - 20 mA or 4 - 20 mA) is simply selected via terminals. Display starts working at an operating current of only 0.3 mA. The low voltage drop of 0.5 V allows application in current loops with low load voltage. Bargraph for quick range overview The digital indicators provide a bargraph in addition to the digital display. This gives you all information on your process variable at a single glance. Versatile setting capabilities Zero, span, and min/max outputs can be adjusted as desired, enabling direct readout of measured values such as temperature, power, displacement, pH value etc. The indicator comes with a symbol set for standard engineering units. The symbols can easily be replaced. Thanks to microprocessor technology, you do not require a high-precision external reference current for parameter setting. Even during operation, the settings can be changed without problems. Loop-powered. Your advantage. The digital indicators are simply inserted into the current loop like passive analog indicators. Since power supplies and their wiring are not required, costs could decisively be reduced, allowing for displays which have been too expensive before. Applications in hazardous locations become easier and less expensive since the costs for intrinsically safe power supplies and wirings can be saved. In addition, the reliability has considerably been improved since a power failure in the control room does not interrupt the data flow. And, in contrast to conventional digital indicators, there is no coupling between measuring loop and power supply. Construction The product line includes indicators in modular cases as well as large and small cases for installation in equipment and control panels. The cases are sealed to IP 65. Floating min/max outputs on request The two optionally available min/max outputs with IS/IS separation can be set as normally closed or normally open contacts. Limit values, hysteresis and switch-on delay can be set as desired. EMC to NAMUR[HOCHSTERN] EMC design ensures reliable measurements even under unfavorable ambient conditions. HART communication The indicators transmit HART signals disturbance-free. Measured value display is not affected.

ProtosÂŽ 3400 X The modular measuring system for pH, conductivity and oxygen in hazardous areas

This device will help you make considerable savings. The perfectly designed ProtosÂŽ 3400 X measuring system is based on a modular hardware and software concept for liquid analysis and offers flexible solutions precisely tailored to the measuring task. It is also possible to easily measure several process variables such as pH/Cond, pH/pH, Cond/Oxy etc. with the appropriate configuration. Similar to a PC, the device which is fitted with a total of 3 slots can be simply retrofitted or modified at any time. With all these advantages, the ProtosÂŽ 3400 X offers a previously unknown level of functionality and reliability, and with an extraordinarily high level of user comfort. A razor-sharp display guarantees superb legibility in the most diverse of light conditions. Also the integrated SMARTMEDIA card allows for the trouble-free saving of configurations, software updates, and measurement data. The hygienic stainless steel enclosure is intended for applications in biotechnology the pharmaceutical industry the food processing industry The rugged, corrosion-resistant coated steel enclosure stands up well to harsh industrial environments. For applications in the chemical industry the paper industry power station engineering water / waste-water technology The ProtosÂŽ 3400 X can be easily integrated into PROFIBUS PA networks

UnicalÂŽ 9000

Combined with the ProtosÂŽ process analysis system and a SensoGateÂŽ or CeramatÂŽ sensor lock-gate, the UnicalÂŽ provides the ideal functionallity of a complete system for automatic control of a pH measurement. It allows highly accurate measurements to be taken even under difficult process conditions such as high pressure, high temperatures, and high levels of impurities. The system can be installed next to the process, within the hazardous area. Maximum availability of the point of measurement: calibrations without disrupting the process, even when measuring directly in the pressure tank. Since the electrode is not dismounted for calibration, the process can continue uninterrupted. This allows problem-free measurements in a pressure tank or in the main pipe. Elaborate and lockable bypasses are eliminated and accuracy increases. Low maintenance Fully automatic electrode calibration in user-defined intervals without interrupting the process. Two buffer solutions are automatically pumped into the calibration chamber. Only the buffer bottles need to be refilled. Cost-efficient Low-wear and low-maintenance pump with extremely low consumption of buffer. Long sensor life also in critical processes When measuring in aggressive media or at high process temperatures, the electrode rests in the calibration chamber and is only briefly moved into the process for measurement. This method decisively increases the sensor life. Safe and easy measurement even in strongly polluted media Sensor cleaning and rinsing is performed in user-defined intervals. Cleaning solution and water are automatically pumped into the calibration chamber. Dismounting and manual cleaning of the sensor are omitted. Distinction between calibration and adjustment This allows you to check the electrode data in the running process. An adjustment is only carried out when there are preset deviations of the calibration values. Constant displacement of the measured values due to small calibration scatters is omitted. Modern fieldbus integration The interfaces to PROFIBUS PA or Foundation Fieldbus allow the UnicalÂŽ system to be integrated directly in a fieldbus network. Of course, also in hazardous locations. Universal adaptation to retractable fittings The modular structure of the UnicalÂŽ allows any retractable fitting to be used. Optimum functionality is achieved with the CeramatÂŽ and SensoGateÂŽ sensor lock-gates. Clear and safe construction All features for a smooth, safe, and low-maintenance operation are provided as standard: water pressure gauge and service switch with alert message and check-back signal for the actual lock-gate position, air filter and water trap, flooding sensor in the housing with alert message.
