Manual

The ATEX MC 315 weight indicator, designed and manufactured by Pavone Weighing Systems in accordance with Directive 2014/34/EU and in compliance with EN 60079-0:2018, EN 60079-11:2012, EN 60079-26:2015, is a weighing instrument with ATEX certification that can be used in environments with potentially explosive atmospheres, particularly in zones ATEX 1, 21 and in zones ATEX 2, 22 (1 and 2 for gases, 21 and 22 for dust). The low energy used by the weight indicator is not sufficient to trigger explosions neither with electrical sparks nor with excessive temperatures (class T4), thus making the use of the ATEX MC 315 weight indicator safe in areas with risk of explosion. The fiber optic connection of the ATEX MC 315 weight indicator allows the necessary information to be brought to the safe area without Zener barriers to obtain the voltage or current analogue output via the S318 interface. As an alternative to the RS232 and RS485 ports, Pavone Weighing Systems provides the following Fieldbuses: Profibus, Profinet, Ethernet IP, Ethercat.

All this at a cost equal to one third of the competition price! The price includes a premium customer service that provides assistance in real time through online video tutorial, telephone calls or visits on site by our senior technicians, who will be at your disposal for any problem. All these characteristics make ATEX weight indicator MC 315 a unique product, which is incomparable to any other proposals currently present on the market.

MC 315 weight indicator has a number of innovative features that make it unique:

specifically designed for the ATEX certifications
the most compact and lightest among the weight indicators
ideal for a wide range of applications
extremely advantaegous cost
free software
free telephone assistance

What is more, the digital weight indicator MC 315 is completely designed and developed by Pavone Weighing Systems and meets 100% the standards established by the ATEX certifications. This means that Pavone Weighing Systems designs, develops, provides assistance and takes complete responsibility for the accuracy of an entirely made-in-Italy product and its compliance with the ATEX standards.

This is a crucial difference compared to companies that simply assemble a transmitter and decline any responsibility for loss of efficiency and malfunctions.

ATEX certification: innovation and safety at the top of the standards

The production of weight indicators has so far mainly consisted in standard products placed in boxes flameproof.

ATEX MC 315 makes a step forward creating a new generation weight indicator since it has been designed on the basis of the ATEX standards, with internal cards that completely comply with directive ATEX 2014/34/UE (entered into force on 16/04/2016). ATEX MC 315 can be used in areas ATEX 1, 21 and in areas ATEX 2, 22 (1 and 2 for gases, 21 and 22 for dusts).

The power supply is low energy (100 ÷ 250 Vac) in order to avoid triggering explosions with electrical sparks or with excessive temperatures (class T4). This makes it a safe tool in areas with danger of explosion.

In the realization of the weight indicator ATEX MC 315, Pavone Weighing Systems has met the most recent norms. In so doing, it has guaranteed a digital weight indicator that is longer lasting and safer than the ones still on the market. Pavone Weighing Systems’ technicians have worked alongside expert consultants following the ATEX regulations on components, materials, modus operandi and assembly up to the conclusion of the long and complex procedure that led to the Bureau Veritas certification, a quality certification body in charge of analysing and certifying the design and the manufacture. The protection methods used have obtained the EU Type Examination Certificate relatively to the design and the Notification of Production Quality (as regards the manufacture).

Working in environments with flammable gases, vapors and mists (zone 1), the Pavone Weighing Systems weight indicator can be interfaced with load cells installed in zone 0. The IIC mark makes ATEX MC 315 suitable for environments with the presence of hydrogen, acetylene and carbon disulfide. In environments with flammable dusts and fuels (zone 21), the weight indicator can interface with load cells installed in zone 20. The IIIC mark makes it suitable for working with conductive powders.

ATEX MC 315 is therefore an intrinsically safe ATEX instrument that responds to the most current international certifications. ATEX standards are harmonized on ISO 9001: 2015 standards.

Compact and ergonomic weight indicator

The ATEX MC 315 weight indicator has been designed to fit into spaces and measurement conditions.

No more 40-50 kilos explosion proof boxes: the R&D department of Pavone has created an indicator of very small dimensions (230x175x97mm) and a weight (1.7 kg) which makes it easily transportable anywhere.

Such a revolution means ease of assembly, less occupation of space and more practicality. The use of the fiber optic cable establishes a new one standard of flexibility in terms of connections, eliminating the need for bulky cables and particularly complex connections.

And stop also to the remote buttons, with all the problems that arise as a result. Now, thanks to the sensitivity of the controls, it is possible to personalize them and set multifunctional buttons as well as to customize the label, the welcome message and the software, with which one can remote applications.

Industrial applications

Low weight and reduced dimensions, along with the technology developed by Pavone Weighing Systems, make ATEX MC 315 a versatile product that can be used in a wide range of applications. Not only can ATEX MC 315 be used in the chemical, petrochemical and mineral sector, but it can also be applied in the paint, pharmaceutical and food industry (i.e. sugar factories and food alcohol industries).

The fiber optic connection allows you to bring the necessary information to a safe area, without the use of Zener barriers. This solution increases the implementation possibilities in various sectors. The native and integrated hardware-software system of Pavone Weighing Systems guarantees the interfacing with all automation processes at industrial level, and makes ATEX MC 315 compatible with all PLC on the market.

Cost-effective

ATEX weight indicator: top quality at a fair price! You spend one third of the competition price. The extreme quality of such an innovative product also consists in the advantage of purchasing a top quality compact weight indicator at a fair price.

The optimization favored by a completely internal production makes it possible to offer the stainless steel weight indicator at an extremely advantageous price, which is up to 70% lower than the current avarage in the digital weight indicators.

With the pluses of a unique system of its kind, built ad hoc and guaranteed for one year by Pavone Weighing Systems.
