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.
The version with rechargeable battery box (charger for recharging in a safe area) is available on request. PWS: 02/2020
