Temperature solutions for Iron and Steel

The iron and steel industry presents a number of challenges to the instrumentation vendor particularly for temperature/process monitoring applications

The iron and steel industry presents a number of challenges to the instrumentation vendor particularly for temperature/process monitoring applications. Ranging from applications where temperatures are simply too hot for contact measurements to those with extreme electro-magnetic interference from arc furnace smelters and applications of many hundreds of temperature measurement points. Harsh environmental conditions with corrosive gas and excessive ambient temperatures all contribute to the design tolerance required from instrumentation in these environments.

Omniflex has many temperature monitoring solutions be they 1 point, 16 points or 600 points and more with high-end specifications, at the same time providing cost effective solutions.

The iron and steel industry has many critical temperature monitoring applications where the potential to cause or inflict tremendous loss if not monitored and controlled.

Compatibility of the front-end temperature measuring system with a variety of supervisory systems is important.

Input isolation from the field and inter channel isolation is crucial to ensuring reliable readings from the plant.

Omniflex offers a single point solution in the Omniterm range and high-density temperature monitoring system catering for hundreds of temperatures at once using Maxiflex with 1500V rms isolation from the field and 500V inter channel isolation.

Maxiflex uses no multiplexing and no rotary switches.

Temperature inputs may be any 3 wire RTD or thermocouples and are individually configurable for any RTD or thermocouple type.

Cold junction compensation and linearisation are all standard features.

Special inputs like optical pyrometers can be catered for including linearisation to temperature if required.

Alarm notification is important to the process operation, each temperature input has 4 soft alarm set-points allocated to it.

The user can configure the option for rate of change alarms instead of set point alarms.

Alarms and set points are configurable via the diagnostic/configuration tools or directly via SCADA or DCS.

Set-points can be mapped to physical outputs to provide local alarm and trip functionality or simply read from the SCADA.

Maxiflex provides a program-less environment for data acquisition.

The system is simply configured using windows based tools for the temperature input type and set-points if required.

No application programs are required; the temperature inputs are scanned automatically and are made available to SCADA or DCS via a data interchange table in the Maxiflex CPU.

Temperatures can be represented in degrees Celsius or Fahrenheit selected by the user.

Many SCADA and DCS system are over burdened with I/O resulting in slow sample rates for data acquisition.

Using front end data acquisition and direct network connections to the DCS or SCADA the workload is distributed and faster sampling can be made.

Networking on existing twisted pair cabling in the plant makes for easy retrofitting to difficult areas of a plant and allows distributed acquisition of temperatures.

Multi-dropping Up to 126 devices along a single twisted pair cable will provide the capacity a total 2016 temperature channels on a single twisted pair cable.

Ethernet gateways to supervisory systems are available and OPC servers allow all compatible SCADA packages to acquire the information from Maxiflex field devices.

Supervisory systems can then utilise the data for pro-active plant management.

Maxiflex provides significant cost savings to high-density temperature measurement, with pricing more competitive than hockey puck solutions for monitoring even before factoring the cable saving, the ability to integrate easily into supervisory and alarm/trip systems makes Maxiflex an attractive solution.

System expansion is trivial and require minimal configuration to commission being measured in hours compared with days on conventional systems and thus passing on the savings to the end user.

Local HMIs can be used with Maxiflex to provide in plant monitoring data to operational staff.

Functionality of the system is varied and tailored to the application's needs.

Maxiflex and a variety of local area network communications solutions including Ethernet to get the information back to supervisory systems easily deliver this.

Local alarm and centralised alarm indication can be implemented with ease.

Integration into Windows operating systems via OPC servers gives access to most SCADA packages on the market.
