Switches Indicators & Gauges

A Blast Furnace Radar is a microwave range finder that consists of a controller, a guide pipe and an antenna.

It is important to control the distribution pattern of charged raw materials to ensure a more stable operation and improve the reaction efficiency.

MWS-20RF-2H

The main advantage of the Semrad Pty Ltd blast furnace radar MWS-20RF-2H is that it is completely unaffected by heat, flames, dust, vapour and shock (note this only applies to the reflector and guide pipe, however the controller and antenna need to be installed in normal temperature areas). The controller can withstand temperatures between  -10 and +50 degrees and the antenna can withstand temperatures between -20  and +150 degrees. The MWS-20RF-2H responds 4 times faster than WADECO standard Microranger. This means that the measurement of bath levels can be carried out quickly and more accurately. It increases operating space due to the fact that the reflector retracts back into its original position (through the use of a robotic arm) when it is not in use. The robotic arm mechanism also eliminates the need for wiring and construction.

The MWS-20RF-2H has a range of built in functions such as:

• A reference point and the required range are easily preset.
• Compatible for use with a personal computer.
• Power supply range of 90∼240V, 50/60Hz.
• Communicates with a Personal Computer by RS-232C.
• 4-20mA, analogue output.
• RS-422 digital output terminals (distance, receiving power level, temperature and alarm).

The MWS-20RF-2H can detect a range of up to 50 meters and has an accuracy rate of 3mm.

All WADECO products come with a 1 year guarantee period from the date of delivery.

Process control is a statistics and engineering regulation that deals with structural design, mechanisms, and algorithms for controlling the output of a specific process. General process controllers have always been high cost items, however, Semrad Pty Ltd have created the Unicont PM-300 series; universal process controllers incorporate at an affordable price.

Features

Features of the Unicont PM-300 series include:

• 2 universal inputs
• Up to 4 output relays
• RS485 modbus
• Autotuning
• 1000 alarm functions
• Auto tuning
• 32 point linearisation
• More than 1 million process configuration possibilities

The Unicont PM-300 series uses Modular design which guarantees short delivery times for the entire range. Unicont PM-300 series includes both PI and PID functions. This enables the control of both heating and cooling. It contains a 2-line, 4-digit bicolour display with a rounding system that can be manually defined for best results. A status indication is provided as well as high and low alarm set points to allow for optimal safety.

Level Display & Control

Semrad Pty Ltd offers a range of precise level measurement instruments, including the MultiCONT PR-100 series. MultiCONT is a universal display and controller, capable of accomplishing complex control tasks by itself. It is a Master for transmitters with HART communications, as well as a universal interface between field devices with HART and other components of the process control system such as PC, PLC, displays and various actuators.

Applied as a Master for devices with HART it can support between 1 and 15 field devices. It can be configured remotely, is wall mounted, can be supplied with both AC and DC power and has an LCD display. The MultiCONT series can be used for remote level metering of liquids, powders and granular mediums, such as cement powder, flyash or grain. It can be applied in situations such as sewage treatment plants, water treatment plants, chemical plants and fuel monitoring.

Level Indicator & Transmitter

The EasyTREK Ultrasonic level indicator and transmitter houses a high performance ultrasonic level measurement transmitter, transducer and processing electronics in one unit. It is a cost saver for liquids and bulksolids metering with all the sophisticated echo detection features of the EchoTREK measurement systems, but packaged into the 2 or 4 wire EasyTREK sensor housing.

The 4 wire version is best for single tank applications as it provides a simple transmitter with a power relay set of contacts that can be programmed with a magnetic key. The 2 wire transmitters are recommended for multiple tank applications, using HART multi-drop systems linked to the MultiCONT controller or a modem and PC.

This level indicator and transmitter can be used for both liquid level or bulksolid measurement in silos, bins, sumps, wells and tanks. It can be applied for tank content measurement or open channel flow measurement as well. It is compact, standalone, economical, fully temperature compensated with excellent signal processing via QUEST™ software and stainless steel sensors. It has secondary lightning protection and plastic or aluminium housing.
