Metal Detectors: Basic Things You Need To Know About

by Vinni S. SEO Executive

Metal detectors are the devices used for detecting the presence of metal. These devices are a useful instrument equipped with highly sensitive sensors and are widely used for finding hidden metal within objects, or even used to detect metal objects buried underground.

Metal detectors are used as security devices and can be handy in various other places. We never know when our places can be in danger with the number of people walking in and out each day. Thus, checking each person who walks into our space with a metal detector is very important. This process of security checking ensures that our place is safe and secured.

There is an extensive range of metal detectors available in the market to fulfill the varied needs of the customers. One can also rely on a metal detector supplier in Delhi to get the product of premium quality. The types of metal detectors you can find with them are-

1. Door frame metal detectors: - These metal detectors facilitate the detection of both ferrous and non-ferrous metals. These are the walk-through metal detectors that are fitted in a door to detect metal that may be hidden on the body of the person passing through the door. These devices are commonly used for security screening at access points in prisons, courthouses, and at airports to detect concealed metal weapons on an individual’s body.
Some of the common features of door frame metal detectors are: -

• The metal detectors come with Auto-Tune.
• They are low-cost single-zone detectors.
• They come with automatic zero adjustments.
• They can be easily and quickly installed and no training is required to install them.
• They come with a sophisticated LED display.
• They have a durable construction.
• They are ideal for excellent automatic working.
• They are waterproof and fire-resistant.

2. Hand-held metal detectors: - These metal detectors are designed for law enforcement security and policing. These can detect all metals both ferrous and non-ferrous and have auto-balancing with the push-button operation. These metal detectors are highly sensitive and auto-tune to every application. Some of the common features of hand-held metal detectors are: -

• They have an auto setting that ensures equal results on a wide range of metals.
• They have the lowest false alarm rates.
• They are cleverly designed for low power consumption.
• They are easy to operate.
• They are of high reliability and provide long-life performance.
• They are known for high sensitivity and high accuracy.
• They can detect all metals including non-magnetic stainless steel.
• They are totally indigenous and their spare parts and maintenance are readily available.
• They have robust and user-friendly controls and features.

However, using both the door frame metal detector and the handheld metal detector will give you the best security at your place.

Factors To Consider When Evaluating A Metal Detector:

• Uniform Detection- It is important to select a metal detector that gives uniform detection throughout the whole interrogation region.

• Electrical and electromagnetic interference- Many times electrical and electromagnetic interference can play havoc with the performance of the metal detectors and often render them unusable. Interference rejection actually separates quality metal detectors from others. Good quality metal detectors use extremely efficient noise inhibition software algorithms. The level of ambient noise can vary from location to location. So, it is advisable to test the door frame metal detector in the location where it will eventually be installed.

• Continually active detection- It is important to select a metal detector that is continuously active without any interference. At no time should the detection circuits or wiring of the detector be deactivated. It is important to check the transit speed of the detector. Irrespective of whether the target object is carried very quickly, slowly, or tossed through the metal detector it should always be detected.

• Metal Types- It is important to select a metal detector that is capable to detect a variety of metals efficiently in a single operating program.
