Magnetic Grill are used for separation of iron particles mixed with dry, granular or free flowing material. Magnetic Grill are made by using stainless steel frames (Round, Square or Rectangular) with Magnetic Rods inside the frame.

These Magnetic Grill are made up of Magnetic Elements which are fitted inside a required size frame. The Magnetic Elements aremade up of hard Ferrite Ceramic Magnets or High Intensity Rare Earth NdFeB Magnets. All the components are made up of Stainless Steel 304/316 material. The overall construction of the Magnetic Grill can also be made as per the customer specification and sizes

The grills are efficiently utilized if contamination is within 1% to 1.5% by weight. For higher levels of contamination Drawer Grills or Multi Drawer Grills should be used.

Low Intensity Magnetic Grillhaving Gauss value of approximately 2, 500 Gauss are ideal for trapping contamination such as Nuts, Bolts, Screws, broken washers etc. these grills are designed to attract larger iron pieces from relatively larger distance.

Medium Intensity Magnetic Grillhaving Gauss value of approximately 5, 500 Gauss are used where the contamination is in particle form, however there may or may not be continuous flow of material to be separated. The contamination size may be as low as 150 microns but not lower than that. The material should be free flowing and non sticky.

High Intensity Magnetic Grillhaving Gauss value of approximately 10, 000 Gauss are employed at locations where separation of contamination particles as small as 1 microns is required. These grills have been designed to attract super fine particles from the carrier material.

In all the three classes of grill, it is a necessity to clean the grills at regular intervals. It is recommended to clean the grill thoroughly before every pass (or as scheduled as per users requirement and experience). More accumulation of Iron particles for long time will reduce the effectiveness of the grill. For highest attraction, the grill needs to be fully clean.

Iron is probably one of the most abundantly available materials in nature and is also being used to a large extend in various products. The use of iron is extensive in all walks of life due to its inherent superior mechanical properties and its availability as compared to other materials. Most of the products are manufactured / produced on machines / equipments which are built using iron. This leads to iron contamination of the products.

The iron contamination may be in the loose form or compound form or it could be in the alloy form depending on the process. Though this is part and parcel of the process, the iron contamination is undesirable in most of the products and contamination levels are governed by guidelines set by BIS and other international standards. This is more so in food processing industry.

A current transformer (CT) is used for measurement of alternating electric current. Current transformers, together with voltage (or potential) transformers (VT or PT), are known as instrument transformers. When current in a circuit is too high to apply directly to measuring instruments, a current transformer produces a reduced current accurately proportional to the current in the circuit, which can be conveniently connected to measuring and recording instruments.

A current transformer isolates the measuring instruments from what may be very high voltage in the monitored circuit. Current transformers are commonly used in metering and protective relays in the electrical power industry.

• Measuring purposes (the CT lowers the current to be suitable for metering instrument) or,
• Protection of the power circuit (input current for protection relays).

Clamp-on or Cable clamp Current Sensors are sensors that are used for measuring AC or DC currents. They are particularly useful for measuring currents flowing in a cable wire in a non-intrusive way.

The clamp-on current sensors are particularly useful for easy and safe installation. They are installed straightforwardly onto a wire going into the electrical load without the need to do any high voltage electrical work. The current sensor consists of a Melexis Hall Sensor (MLX91208) and a patented ferromagnetic structure packaged in a robust plastic housing.

This non-invasive current sensor (also known as a split core or cable-clamp ) can be clamped around the supply line of any electrical load to tell you how much current is passing through it. It monitors the magnetic field around a current-carrying conductor and outputs a voltage proportional to the current.

The clamp-on current sensors measure loads from +/-5 Amps to +/-230 Amps which makes it great for building your own energy monitor to keep your power usage down, or even building an over-current protection device for an AC load.

Die casting is the process in which molten metal is poured or forced into steel mold. Die casting is the most efficient process for high volume precision parts producing the best tolerance & rapid production. The mold known as tools or dies which are created using steel and they are specially designed for each project. This allows each component to be created with a accuracy and repeat ability. Aluminum, Zinc, and Magnesium are the most commonly used die casting alloys.

Die casting is a cost effective process for components requiring high volumes and complex geometries. Die casting is a net-shape process, and cost savings can be achieved by eliminating secondary machining and assembly operations required by other processes.

Magnetic Chutes are used for trapping and separating iron particles mixed with dry, granular or powdered materials. They are generally used where flowing material characteristics are sticky and non free flowing. They come with either Conical Magnets fitted on hinged doors or Magnetic Plates fitted on the sides. These systems are easy to clean and maintain.

Energy meter CTs made using hybrid cores are DC immune current transformers for energy meters meeting IS 13779 / IEC 62053. The CT is small in size with customized casing and metal shield, (optional) for protection against external magnetic field. The wound CT is epoxy potted for durable and long life performance. Number of turns can be wound/adjusted as per customer requirements. CTs can be provided with or without metal shield in custom casings.

Magnetic Filters are used for filtration of iron particles from products in liquid/slurry form. They are essentially used in chemical, food, pharma and oil industries. They are also frequently used in hydraulic circuits in cooling systems. The Filter Magnets are made up of either Ceramic or High Intensity Rare Earth Magnets.

The C-Core is a laminated soft ferromagnetic core featuring superior material characteristics such as high linearity and very low hysteresis. It is available with two different materials: Ni- Fe and Si-Fe.

The core is designed for high-speed contactless current sensing in combination with a magnetic field sensor, i.e., Hall sensor, and a current conductor. Furthermore, the core protects the sensor from parasitic magnetic fields caused by nearby conductors or other magnetic field sources.
