What Are Field-Bus Systems? A field-bus system is a data network with the objective to receive data from a production process, exchange data between devices or machines, control steps or processes in production. Data transmission happens serially with digital signals (equivalent to Internet data transmission.) The most basic design of such a data network is a -wire cable with various individual sensors (e.g. Pressure transmitters), actors (e.g. solenoid valves), controllers, periphery units, and control units (e.g. PLC, industrial PCs) connected at any point. BUS participants need a suitable interface, which transfers flow of data. Each individual component gets its own address. Structure of a Bus System: Bus master e.g. PLC Node Node Node Node 0 Node e.g. pressure transmitter e.g. valve e.g. temperature sensor Remarks: Communication of process data is performed by means of every individual sensor, component, and so on, being connected via it s own wiring to high layer control. Advantages: Easy wiring with clear reduction of cabling (best case: only two cables) Clear structure Diagnostic functions, connected units may be checked on functionality All system functions are available in high layer control at any time High level of transmission safety, information may be checked on validity through multiple transmissions Easy to be enlarged, since at any place of network a unit may be added Easy implementation into higher leveled systems: - connection to other bus system - distance diagnostic systems - service units -877-GO HYDAC Electronics Catalog

Specialty Pressure Transducers HDA 400 & 700 - Shipbuilding and Offshore About HDA 400 Pressure Transducers: This pressure transmitter, which has been specially developed for shipbuilding and offshore applications, is based on a very robust and accurate sensor cell with a thin film strain gauge on a stainless steel membrane. All parts in contact with the fluid are in stainless steel and are welded together. Since no seals are required in the sensor chamber, leakage is eliminated. The 4 to 0 ma output signal in two conductor technic enables connection to the relevant evaluation electronics. Since accuracy varies markedly with the temperature of the fluid being measured, this instrument offers outstanding characteristics in this respect. Areas of application are pressure monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.

IIC IIC is the highest possible flash point range in the standard. II specifies the area of application for all environments with an explosion hazard, except for flame-proof protection. (Flame-proof protection is designated by ) C designates the actual flash point range (i.e. the ignitability of the environment.) Class C is the highest requirement, i.e. the environment accepted to be the most critical. The subordinate classes A and B can be equipped with a C registered unit. C means, for example, that gas mixtures with up to % of hydrogen will not ignite. T6 Temperature class T6 is the highest temperature class specified in the standard which ensures that, at a maximum ambient temperature, the surface temperature never exceeds 85 C. Components of temperature class T6 can of course also be used for lower classes T - T5. Applications: Approvals: 7 Electronics Catalog

Pressure Switches EDS 00 - Shipbuilding About EDS 00 Pressure Switches: The EDS 00 is a compact, electronic pressure switch with digital display. The pressure measurement is based on a thin film strain gauge sensor cell in stainless steel. All parts in contact with the fluid are in stainless steel, and are welded together. Since no seals are required in the sensor chamber, leakage is eliminated. Two relay switching outputs with N/O function and an additional analog output signal (4 to 0 ma) enable the pressure switch to be incorporated into the most modern control concepts. The switching points and the corresponding hysteresis can easily be adjusted via the keypad. For optimum adaptation to a particular application, the unit has many additional adjustment parameters, e.g. switching direction of the relays, switching delay times. Areas of application are pressure or maximum value monitoring on marine transmissions, diesel engines, pumps and general hydraulic and pneumatic systems.

Temperature Switches ETS 700 About ETS 700 Temperature Switches: The electronic temperature switch ETS 700 is used together with the temperature sensor TFP 00, which was specifically developed for tank mounting. The 4 digit display can indicate either the actual temperature, one of the switching points, or the maximum temperature. The maximum temperature indicates the highest temperature which has occurred since the unit was switched on or last reset. The 4 switching outputs can be used to control heating and cooling processes in hydraulic systems, as an example. All switching and switch-back points, which are independent of each other, can be adjusted very simply via a membrane keypad. For incorporation into monitoring systems (e.g. with PLC), an analog output (4 to 0 ma or 0 to 0 V) is also available.

Flow Rate Sensors EVS 00 Flow Rate Sensor About EVS 00 Flow Rate Sensors: The EVS 00 series flow rate sensors are designed to accurately measure the flow-through volume of fluids in hydraulic systems. The unit uses a stainless steel turbine wheel internal to the construction, which converts the media flow into a 4 to 0mA output signal. The in-line mounting design allows for most accurate and up to date flow measurements. The EVS 00 also offers two additional hydraulic ports to accommodate additional sensors, ex. temperature and pressure transducers. The design of the flow meter incorporates a lightweight aluminum housing with accurate and stable measuring elements. The unit uses the Woltmann Turbine principle to measure flow. The fluid enters the housing and passes through straightening blades, which assist in stabilizing the media into a laminar flow. The stainless steel turbine wheel is rotated by the media flow, which then influences the magnetic field of the inductive receiver with the passing of each turbine fin. The inductive receiver is the sensing element of this flow meter. This influence produces a voltage pulse in the receiver, which it then converts into a 4 to 0mA output signal. This design provides precise data within the entire measurement range of the unit, and is relatively tolerant against minimal, gritty contamination. The meter also allows for exceeding flow of up to 50% of the maximum range for short periods of time.

Normal measurement Purely a display function where the measured values are displayed immediately. Ex: When HMG is measuring with pressure sensors to act as a digital gauge.. Curve measurement The measured values are displayed and simultaneously stored continuously in the internal memory. The courses of the curves can be printed out on the printer as soon as measuring has stopped, or transferred to a PC and viewed with the software.. Log measurement The measured values are displayed and can be stored as log entries in the internal memory. This method of measurement is used primarily for long-term measurements (e.g. one week, one month, one year etc.). The log entries can be printed out on a printer as soon as measuring has stopped, or transferred to a PC. The internal memory can store up to 50 different curves and logs with 50,000 measured values in total. To optimize your measurements the unit has a wide variety of additional functions: Choice of language The user may define which language the unit will display the data and parameters. 49 Electronics Catalog

Diagnostics HMGWIN The HMGWIN PC program expands the measurement options of the portable HMG 00 data recorder. HMGWIN is compatible with Windows 95/98/NT, user friendly, an interactive software package that allows the user to download the stored data and study it in greater detail. For the user who wishes to store or further evaluate the recorded measurement curves and measurement logs, this HMGWIN provides a range of useful functions. Features: Transfer and Storage of curves and logs from the HMG 00 to a PC. Viewing of up to 4 different recorded curve or log measurement simultaneously on the monitor. Superimposition of curves Parts of different curves can be superimposed in a new graph, for example to show the wear and tear of a machine (new condition/current condition). Straight edge function As with a straight edge, you can measure the curves using the mouse (exact time and amplitude value). Absolute measured values and also relative measured values (measurement in relation to a set marker) can be displayed. Zoom function Using the mouse, part of a graph can be framed. The framed area appears as a new graph, enlarged accordingly. Online function The portable data recorder measures and transfers the current measured values straight onto the PC. These are then immediately displayed as a graph in realtime (comparable with the function of an oscilloscope). The graph displayed can be stored if there are any interesting results. Portable data recorder Settings can be transferred to the PC and may be stored. The reverse is also possible, so, for example, settings for taking measurements on a particular machine can be fed into the HMG 00 again and again. Data conversion HMGDESK can convert the HMG 00 data into some other data formats. This means, for example, that the recorded curves can be transferred to many other PC programs (spreadsheets, database, word processing etc.) and further processed.
