The Usage of Wire Seals in Weighing and Measuring

The Usage of Wire Seals in Weighing and Measuring

Posted by Steve Diebold

The use of wire seals to secure weighing, measuring, and metering equipment isn’t something new anymore as it dates back to the 19th century. For more than a century, AC&M has been keeping up with the evolution and advancement of wire seals and has produced not just the usual lead wire seals, but also modern plastic and hybrid metal strap seals that do not require any special tools to apply them. This made the company the leading expert in the industry.

Mechanical scales, postage meters, and time clocks were among the earliest uses of wire seals. Tampering with or accessing these measuring devices without authorization is made more difficult by the seals. Moreover, seals made of lead and wire were utilized on the majority of early scales as well as other metering systems. A hand press is used to firmly shut a lead-wire closure. However, as a result of the possible health hazards associated with handling lead, this sealing procedure is no longer as widely used as it was before.

It is currently common for wire seals to be made of aluminum or plastic. Due to their tiny diameter, many measuring and metering devices necessitate the use of braided wire in order to ensure the seal is tamper-proof. Therefore, braided wire remains popular.

Types of Wire Seals and Its Applications

The crimp wire seal is one of the most commonly used seals for measuring and metering. These seals are composed of lead, aluminum, or aluminum alloys. A seal press or pliers can be used to squeeze the wire into the holes and seal it in place. When a seal press uses a hardened die, the seal may be matched to the press by the marks pressed into it. These might be simple patterns, or they could be numerals or characters. AC&M has two press sizes to choose from. To properly crush an aluminum seal, you'll need a stronger press with a longer handle than you'll find with a lead press.

Self-locking wire seals, such as barcoded seals, are preferably used nowadays. This is because when using self-locking wire seals, you don't need a crimping tool to secure the seals anymore, unlike crimp wire seals. A lot of these types of seals are readily available from AC&M. However, AC&M made a game changer by especially developing the PSW-97 wire seal, which features a stainless steel locking plunger. This seal may be color coded and customized to suit the needs of the recipient. The PSW97 website has a wealth of information about the seal's benefits.

Snap seals, on the other hand, are simple steel wire seals that let you bend and lock the seal shut with your hands, securing the wire in place as you do so. This necessitates cutting the wire or severely bending the seal to open. All Snap Seals are available in basic or branded versions. They may be ordered in either unfinished metal or colored metal.

Furthermore, wire-wrapped cup seals are the best way to detect tampering. The saw-toothed bronze cross locking ring is housed in this two-piece disc that is combined and linked with the wire within. This makes the seal so robust and compact that only razor-sharp cutting instruments can get through. Moreover, cutting the wire is the only way to remove it. Hence, no matter the case, proof of tampering will always be shown. Tamper evidence is critical in applications involving high value and potential danger, such as those for which these devices are being employed.

Uses of Wire Seals are Boundless and Extensive

There are many more applications for measuring and metering than can be covered in this brief overview. Utility metering is one of the most prevalent uses of security seals for measuring. Examples of well-known uses include taxi meters, laboratory test equipment, and fuel meters. Wires are commonly used to seal metering and measuring instruments in production facilities for filling, weighing, etc., such as on liquid delivery trucks and transfer points; truck scales; postal weigh scales; traffic count devices; remote weather stations; and water level sensors. There are a lot of options in these specifications.
