ATEX zone
Masiste specialises in measuring and weighing in specific environments, including ATEX or explosive atmosphere zones, classified as: zone 0 (permanent presence or for long periods of time), zone 1 (likely to form under normal working conditions), zone 2 (unlikely to be present for short periods), zone 20 (where combustible dust is present or may be present during normal operating, start-up or cleaning operations in sufficient quantity to produce an explosive atmosphere), zone 21 (where a dust cloud or dust layer is likely to form under normal working conditions) and zone 22 (unlikely to be present for short periods).
ATEX scales
The scales for ATEX zones 1, 21, 2, 22 from Masiste have various types of indicators and extras such as rechargeable battery power supply, communications, dosing, etc. The scales are accompanied by the ATEX declaration of conformity for the group in accordance with current regulations. Protection Type Ex II 2GD IIC T4 T197°C X. Masiste ATEX scales allow you to measure and weigh in atmospheric conditions, air and flammable substances in the form of gas, vapour or dust.
ATEX indicators
ATEX indicators are high performance, easy to program and use. With IP68 stainless steel protection, they are suitable for II 3G Ex nR IIC T6 Gc X and II 3D Ex tc IIIC T85°C Dc IP68 X zones. Their waterproof numeric keypads and display make them suitable for use on a table, column or wall. Masiste ATEX indicators allow digital calibration and configuration from keyboard or PC, as well as systems of use: Net/Gross, lb/kg conversion, free conversion factor (for counting systems, litre counters, etc.), total sum of weights, formulation, +/- control, with quick insertion of target and thresholds and even weighing in percentage or piece counting.
Electronics and accessories
Masiste offers its customers protection systems for electrical equipment in ATEX Zones, being suitable if they have protection modes labelled as flameproof enclosure, increased safety, intrinsic safety, internal overpressure, oil immersion, powder insulation and encapsulation. Ask our team of professionals about the most innovative and advanced protection systems for electrical equipment in ATEX zones on the market for your company or business.
Load cells
Masiste’s ATEX load cells allow you to measure force in difficult environments where there is a risk of explosion. The load cells are certified type D or type G, whether for dust or gas, and their capacities vary depending on the application. With IP68 protection guarantee, their applications can be diverse: weighing platforms, pallet weighers, silos or bagging machines, truck scales, etc.
ZENNER barriers
Zenner barriers are specifically designed for use in high accuracy / high resolution weighing applications. Zenner barriers feature a redundant Zenner diode design for complete protection even if two diodes fail. When a fault condition occurs, the diodes conduct and blow a fuse, opening the circuit to the load cell(s). In addition, replaceable fuses protect the barrier against wiring errors during installation and service. These fuses can be replaced without removing the wiring or connectors. The ISB05 and ISB05X are designed to operate with terminals that provide a maximum excitation voltage of +5 volts DC with reference to signal ground. The ISB05 and ISB15 are intended for general purpose, safe area use, featuring NEMA Type 7/9 fireproof enclosures for use in hazardous areas.
