Indicator

The microcontroller based electronics indicator is extremely reliable and user friendly . The built in RS232C communications interface allows easy connection to a computer and printer , and enables an effective computerized weight management systems .

Display : LCD 128 x 64 with backlighting show weight value : 6 bit , show working life of battery show strong of signal .

Hold on the peak value Can contact with computer by RS232. Work principle
BWI 31 wireless indicator is able to connect with Max 16 nos. wireless weighing pads , indicator will list every weight from pads which it searched automatically , then show total weight at the one screen with the listing .

One of advantages is that no need any cable / wire for connection in the whole system.

On Board Weighing Systems used in forklifts and front end loaders are usually hydraulic based using a pressure transducer fitted into the hydraulic lines to provide a pressure reading which is translated into a weight reading by a digital weight indicator The pressure in the lifting cylinder is tapped at a location where the bucket will be parallel to the ground to achieve repeatability. The low level signal from the pressure sensor is amplified and filtered by the high precision monolithic A/D converter and converted into digital format. With the aid of pressure and position sensors, the electronics evaluates complex dynamic weighing calculations to easy to read data shown on a large TFT colour display screen, all in real time. The dynamic weighing feature allows for weight measurements to be carried out even whilst the vehicle is in motion, preventing the need for lifting operation to be momentarily stopped The digitized data is further processed and stored according to the customer need and application.

HotMetalRailWeigh is a static weighing system designed for the weighing of hot ladle cars. Precision QS-G load cells made in the form of the rail determine the weight of the ladle car. This is done by positioning the precision load cells beneath each of the wheels of the ladle car. The load cells and teflon cables are designed to withstand temperatures of over 250C. The weight values are acquired and processed with the use of weighing electronics and customized PC systems.

Benefits

• Static weighing of hot ladle cars.


• Pitless and gap free design.


• Simple installation no frame needed.


• Suitable for very harsh environments


• Precise determination of hot metal output

The overeahead crane is designed to weigh the ladle at the upper sheave assembly to measure amount of liquid metal while pouring into a furnace. This will improve the yield as well as the end point control.High temperature load cells and rope weight compensation facility gives accurate results.
