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.

MWS-ST/SR-2WG Micro-Gunn

MWS-ST/SR-2WG Micro-Gunn producded by Semrad Pty Ltd was developed as a substitution for infrared hot metal detectors (HMD), laser/optical barriers and gamma ray sensors for product tracking in steel mills.

MWS-ST/SR-2WG Micro-Gunn consists of a pair of transmitting and receiving antennas, connected to separate controllers by circular wave guide tubing. The detection signal outputs when the microwave beam is reflected by the slab/strip into the receiving antenna.

Advantages

MWS-ST/SR-2WG Micro-Gunn required no maintenance. It operates flawlessly in high vapor areas (compared to optical and infrared based sensors which do not). It has a high degree of precision and is economical, reliable and a great hazard free solution for product tracking in continuous casting and rolling mills.
