LeghornGroup produces different models of seals for gas, water and electrical meters.
In particular, LeghornGroup was among the first companies to produce a self-locking wire seal more than 30 years ago. The evolution of the standard Twist seal is our Twistseal RFID UHF.

HOW TO USE IT
Insert the cable in one of the two holes on the body of the seal, paying attention to insert the same cable in the corresponding hole in the inner plastic cylinder.

To close it, turn the handle of the seal 360°. Once closed, it is advisable to snap off the handle. It is impossible to tamper the seal once it is secured.

RFID CONNECTION LOCK is a protection system for fittings of water and gas supply, simple to apply, which operates as a seal; it is composed of two semi-circular parts which fit together in a permanent way – one inside the other – and that cannot be separated without prior split them. The transparent plastic material with which the seal is realized allows to check the correct closure of the valve.
The presence of an integrated RFID tag – available in the frequency band HF (NFC) and UHF, not accessible from outside, allows associating a unique serial number with the closure system CONNECTION LOCK, number that can be read remotely and without line of sight with the operator.
With this identifier, the meter is automatically identified, by using RFID handheld readers or even smartphones and tablet from the market, assuming use of NFC technology.

RFID CONNECTION LOCK mounts an RFID tag whose electronic chip has its own unique coding system and cannot be cloned. This feature enables a safe and reliable automatic identification of the seal, or meter / user associated with it.

The outer casing of the seal, made of high-impact resistant polycarbonate can be customized with marking and numbering (alphanumeric code with inkjet printing technique, laser engraving, or in quantity also embossed lettering).

RFID HF / NFC OR RFID UHF SEAL FOR ENERGY METERS

• The RFID technology provides automatic, contactless and without line of sight identification of the seal associated with the meter.

• It can be read quickly and accurately through portable devices operated by the staff.

• The RFID chip can also be used to store additional information.

• One can easily write into the chip by using standard RFID read / write devices. The information can be password protected.

The post Meter Seal UHF/HF/NFC RFID CONNECTION LOCK appeared first on LeghornGroup.

With its cable diameter of 1 mm, it can be used in any locking situation. Particularly suitable to control counter meters of electricity, water and gas.

The body is completely made in anodised aluminium (*) and a steel cable comes out of it.

Once inserted the opposite end of the cable into the hole, and pulled it to the maximum possible extent, there will be no way to open the seal unless by breaking it with good shears.

(*) Anodising is a non- spontaneous electrochemical process by which a protective oxide layer forms on the surface of the treated metal and protects it from corrosion.

The wire has a 1mm diameter and is composed of a central wire of 0.5mm and a second wire of 0.3mm that revolves around.

It is suitable for every type of wire seals especially is a sturdier wire is needed.

We generally supply it in different spools weight and in pre-cut lengths which vary from 10 to 150 cm long.

The 1mm diameter galvanized sealing wire for seals is the most used in the field of wire seals.
Its spiral shape is suitable for being used with lead seals and the related lead seal press.
Once the lead seal is pressed down correctly, pulling out the seal would not be possible.
We generally supply galvanized sealing wire in various reels weight and in parts which vary from 10 to 150 cm long.

The idea of manufacturing plastic custom seals comes from the traditional custom lead seals.

Plombex may also be used with different type of sealing wires, metal core custom string or traditional string.

Plombex are properly sealed with a lead seal press.

They are mainly used to seal fire extinguishers or first aid kit but they may have a decorative function in the food and cosmetic industry.

Plombex are available in different colours including silver, gold and bronze
