System Components

Analog measured values are indicated, evaluated and calculated by process indicators. Large displays offer easily readability at all ambient conditions. The universal inputs enable the connection of current, voltage, RTDs and TCs. Loop powered indicators require no power supply and can be universally used in current measuring circuits. They can be easily installed in intrinsically safe applications. Fieldbus indicators support all bus devices and indicate the values communicated on the bus.

Heating and cooling are energy-intensive processes. As the costs are constantly rising and, depending on the industry the energy costs amount up to 40% of the total industrial production costs, energy optimization is a very current topic.

They use flow, temperature and/or pressure to calculate the energy content of liquids and steam.

Power supplies and barriers for sensors and transmitters

Power supplies and barriers supplies e.g. a transmitter with power, if required also in the Ex-area, and then transmits the galvanically isolated signal. With the optionally available HART® monitoring the status of the transmitter is monitored. Thus, even just briefly occurring errors can be easily located.

Quick and simple access to field devices and network data

Gateways and modems are system components that provide easy access to field device and network data. A modem provides a protocol conversion, e.g. HART/USB or FF/Bluetooth, and is used with a handheld configurator or computer. A gateway provides a parallel network access point for, e.g. device configuration software (FieldCare). In addition to the protocol conversion, gateways offer additional functions, e.g. network and device status monitoring, which can be viewed with a standard web browser.

Operating principle:

Modems and gateways provide protocol conversions, allowing software on computers or handhelds to talk directly to field devices. A modem provides a point-to-point connection: on one side of the field device and on the other, depending on modem, a USB computer port or Bluetooth wireless interface. A gateway is a system component and connects the Ethernet port of a computer to any fieldbus device in the network. Device configuration software or a web-browser on the computer controls device access.

Benefits:

• Simple connection to devices in the field
• Quick and easy commissioning of field devices
• Network and device status monitoring (gateways)
• Concise device diagnosis to NAMUR NE 107 standards (gateways)
• Remote monitoring and maintenance via web-browser (gateways)

Handheld communicators for commissioning and maintenance of field devices

Field Xpert field communicators are rugged mobile computers that allow easy local access to field devices via Bluetooth or WiFi. Designed for use with HART and FOUNDATION Fieldbus devices, they can be used to set-up, trouble-shoot and analyse devices. Depending on the version, they can also read wireless RFID NFC device identification tags. Field Xperts also connect to Endress+Hauser’s device data base, allowing device manuals, certificates and calibration data to be downloaded on site.

Operating principle:

Field Xpert connects to a field device in one of two ways. For a field connection, either a HART or FF/Bluetooth modem is used. For a network connection a WiFi interface is required and the device is accessed via a FOUNDATION Fieldbus or HART gateway. A USB interface allows device configuration data to be archived on a computer.

Field Xperts can be equipped with HART and/or FOUNDATION Fieldbus Device Xpert software. In addition to device configuration this allows device diagnosis according to the NAMUR NE 107 standard and comparison of configurations. Access to Endress+Hauser’s device data base allows the download of manuals and other device life-cycle data. Device driver (DD) libraries are kept up to date automatically.

Benefits:

• Quick and easy commissioning in the field
• Concise device diagnosis with cause and remedy information (NAMUR NE 107)
• Archiving of device configurations for future comparison
• Online device life-cycle data, e.g. manuals and certificates
• Remote identification of devices using RFID NFC tags

Surge arrestors for over voltage protection

Plant availability is very important as even short failures in production may cause high losses in sales. Therefore, respective protection of the devices e.g. surge protection as well as a high availability of plant parts needs to be ensured. Direct and indirect lightning as well as switching operations within a process can produce voltage overloads into supply lines and communication circuits, such as fieldbus systems.

Surge arresters are primarily used in process automation and in measuring and communication technology within the chemicals, pharmaceuticals, water and wastewater sectors as well as in the food industry.

Measuring Principle:

Surge arresters are used to protect electronic components in field devices from damage. It ensures that overvoltage surges which occur in signal cables (e.g. 4 to 20 mA), in communication lines of fieldbuses (HART, PA, FF) and in power lines are safely passed to ground. The functionality of the electronic component to be protected is not affected as, using the impedance-free connection of the protection unit, interference voltage drops cannot be introduced.

Portfolio:

• Surge arrester for DIN rail mounting
• Surge arrester for field mounting
• Surge arrester for signal cables
• Surge arrester for communication lines of fieldbuses
• Surge arrester for power lines

Benefits:

• Optionally available with ATEX and SIL2 intrinsically safe approvals
• Surge arrester for field or DIN rail mounting available
• Surge arrester for power lines, signal cables and communication lines of fieldbuses available
• Increased plant availability as surge arrester is perfectly matched to the electronic components involved in process automation and process measuring technology

Cost effective integration of moving, changing and measuring points

WirelessHART provides an extremely flexible method of integrating measuring points into monitoring systems. It can be used in systems subject to regular expansion, e.g. well heads, those constantly on the move, as well as on rotating or moving machinery. As the systems are self-organising, they require minimum time to set up, integrate and commission. Endress+Hauser’s adapter concept also allows WirelessHART communication to be quickly added to existing 4 to 20 mA devices.

Operating Principle:

A WirelessHART system comprises a gateway, which is connected to the monitoring system, and up to 250 WirelessHART field devices. Endress+Hauser’s adapter allows any HART or 4 to 20 mA device to join the wireless network. The instruments transmit their measured values at regular intervals to the gateway, which collects them and makes them available to a connected application. FieldCare device configuration software can be used to configure the network.

Benefits:

• Rapid and flexible installation
• Suitable for moving and rotating plant equipment
• Suitable for changing and mobile installations
• Bridges obstacles and integrates difficult-to-access measuring points
• Upgrades legacy technology
