Stratos® ProNew operating concept.

The Stratos® Pro series realizes a completely new and especially user-friendly operating concept in modern analyzers. Studies have shown that operator errors more frequently lead to downtime than hardware defects or malfunctions. A user-friendly design and intui-tive operation has been given the highest priority in the new series.

Stratos® Pro Setting the standard.

The unique backlit display of the Stratos® Pro changes between six different colors to clearly signal operating states. The normal measuring mode is white. Information text appears on a green screen and the diagnostic menu appears on turquoise. The orange HOLD mode is quickly visible as is the magenta screen which indicates maintenance requests and sensor wear.

The alarm status has a particularly noticeable red display color and is also signaled by fl ashing display values. Unreliable entries or false passcodes cause the entire display to blink red so that operating errors are noticeably reduced.

Stratos® ProClarity of display.

A pin sharp and high-contrast LC display provides optimum legibility, even in the most difficult lighting conditions. Instead of pixilated elements which are sometimes difficult to identify, the display utilizes high-resolution, self-explanatory icons. Longer text displays are scrolled horizontally in a large, clearly legible font: a scrolling ticker line is more easily and reliably comprehended than text in jumping lines.

Memosens® is a new open standard of a smart,

contactless sensor connection system.

A Memosens® seal of approval guarantees quality

and compatibility.

This allows the user to choose from different sensor

manufacturers.

The New Memosens®.

The new Memosens® System is characterized by a patented quick connector that enables easy opening/closing without twisting the cable.

The key element of the system is the signal processing carried out in the sensor cap using inductive, contactless data transfer and power supply.

This allows reliable measurement completely insensitive to ambient conditions such as– humidity– corrosion– salt bridges – bad contacts – poor galvanic isolation – cables that are unsuitable or

too long

The system can even be connected under water. The connector is metal-free. Perfect galvanic isolation enables disturbance-free data transfer. Connection of a solution ground or equipotential bonding (EB) is not required.

7

Stratos® ProThe complete range.

Stratos® Pro facilitates the opera-tion of almost all standard sensors available on the global market, thanks to its innovative wiring technology in the 2- and 4-wire designs. The Stratos® Pro was designed to provide the greatest possible flexibility for the user. Even under the harshest of ambient conditions, the devices can be used in process applica-tions of all types to collect mea-sured values for pH, ORP, conduc-tivity (conductive and inductive), or oxygen.

Memosens® provides added value.Memosens® allows using precali-brated sensors so that costly on-site handling time is reduced and plant availability increases.

Predictive diagnostics combined with improved asset management enable innovative maintenance strategies.

Robustness.

All the electronics in a Stratos® Pro are encapsulated in the door module of the device.

New industry design to be used for applications

even under the harshest of ambient conditions:

Stratos® Pro. Fully encapsulated and protected

in shatter-proof and corrosion-resistant plastic

enclosure with outdoor approval rating.

Stratos® Pro Tough.

The reinforced and UV-resistant plastic enclosure of the Stratos® Pro supports the product func-tionality. There are neither prominent control elements nor those with a high mechanical load to be found on the practical, smooth, dirt-proof design. Injection molded, directly sealed keys are made from high-quality EPDM so that it is no longer necessary to stick films, which had to perform a sealing func-tion, onto the front of the device.The high IP 67 protection rating is retained under all conditions – reliable and safe operation is guaranteed in the range from –20 °C to +65 °C, even for oper-ation in hazardous locations.

Stratos® ProAll-round resilience.

The display window of the Stratos® Pro is connected directly to the plastic enclosure during the innovative molding process. It is made from reinforced safety glass, is scratch-resistant and UV-resistant. All the device's electron-ics are completely encapsulated in the door module: there are no exposed PCBs. The large rear unit can be mounted separately. All electrical connections are made by means of plug-in terminals in the door unit, so that if the door module is replaced, the complete cabling can be retained in the rear unit.

Stratos® ProSimple installation.

• Wall, post/pipe, or panel mounting

• All parts are easily accessible

• Large terminal compartment

• Rear unit can be pre-assembled

• Also suitable for rigid metallic conduits

• Replaceable plug-in terminals

• Replacement of the electronics without new cabling

Functionality.

Stratos® Pro 4-wire devices

Stratos® Pro 2-wire devices

From the wireless service interface to the complete HART

communication system, the Stratos® Pro series offers a wide

range of reliable functions for 4- and 2-wire devices.

The devices can be used in multidrop mode and are certified

for the handheld and asset management systems of the

leading manufacturers.

Unrivalled circuit technology ensures low self-heating and

an extremely long service life.

The 4-wire models from Stratos® Pro are equipped with the VariPower® broad-range power supply unit. This facilitates the use of the same device model for power supplies of 20 to 253 V AC/DC. Reliable operation is thereby guaranteed worldwide, even with fluctuating qualities of power supplies.

A number of outstanding techno-logical properties make the Stratos® Pro series the new benchmark for 2-wire analyzers. Colored screen backlighting has been realized for the first time in this device class, with the lowest possible electrical power. In contrast to all 2-wire devices previously available on the world market, two digital inputs are available as well as an analog input plus a second output for another measured value.

Globally ready.

• VariPower® power supply unit 20 ... 253 V AC/DC

• 2 x RS 485 for 2-channel operation with contactless sensors

• 2-channel mixed operation for analog sensors and contactless sensors

• 4 relay contacts for alarm, limit values, maintenance request

• PID controller

• The new benchmark for 2-wire devices

• Full functionality with 2-wire supply

• –20 °C to +65 °C permitted also for hazardous-area applications

• RS 485 for operating contactless sensors

The new benchmark.
