Mitsubishi Electric gets into remote monitoring; Schmersal breaks new sensor ground.

Mitsubishi Electric Launches Remote- Maintenance Service

Mitsubishi Electric has launched the M’s BRIDGE™, what it calls a “global remote-maintenance service for the continuous monitoring, inspection and data analysis of elevators.” Features include faster and more convenient elevator repairs based on 24/7 remote failure detection and analysis; automatic detection and alerts, even for minor signs of potential malfunctions; and efficient maintenance based on collection and analysis of remote inspection data that technicians can use in regular onsite inspections.

Using the Internet of Things and big data via Mitsubishi Electric’s Maisar® original artificial intelligence, the platform has begun in Hong Kong and Singapore. The company’s goal is to expand to other Asian regions, Europe and the Americas across 15 countries by the fiscal year ending in 2022.


RFID-Based Safety Sensor

The Schmersal Group of Wuppertal, Germany, has released the EX-RSS16, which it says is the first radio-frequency- identification (RFID)-based safety sensor designed in accordance with ATEX Directive 2014/34/EU and can be used in EX zones 2 (gas EX, category 3G) and 22 (dust EX, category 3D). This, it adds, means the product combines functional safety in accordance with ISO 13849 and explosion protection.

Additionally, the sensor features ignition protection classes Ex ec and Ex tc, covering the explosion-protection function without the requirement of another energy-limiting device. Schmersal launched this new development this year.

The wear-free safety sensor is designed for position monitoring of various kinds of safety equipment, including door monitoring and rotating, lateral shifting or removable safety equipment. As latching is optional, the variant with magnetic latching ensures a door is held closed, even when there is no voltage.

Three different actuation directions allow flexible installation positions. The sensors also have an optional diagnostic output or serial-diagnostics (SD) interface. Up to 31 safety switchgear devices with serial diagnostics can be connected in series, which means the diagnostics data from each device can be transferred via the SD gateway and a fieldbus to a controller for such messages as status and error reports.
