PROD TAG 420
PROD TAG 420 is a precise positioning personal tag for RealTrac Positioning (RTLS), mounted on an industrial smartphone. The tag and the smartphone form a single wearable device, so employees do not need to carry them separately.
The smartphone provides communication, photo capture and outdoor navigation; the tag provides indoor positioning with an accuracy of up to 1 m and safety functions. The tag signal is received by PROD POINT 520 access points (explosion-proof version: EXIA POINT 520), and the server calculates the coordinates and shows the employee on the map in real time.
Areas of application
- Oil and gas facilities, refineries, chemical plants
- Energy and transportation
- Mining and metallurgy
Capabilities
- Positioning without blind spots: smartphone GNSS outdoors (up to 3 m), tag UWB indoors (up to 1 m), BLE for zonal presence tracking
- Support for the RealTrac Collision Avoidance System (CAS): the vehicle driver sees the employee on the screen
- Emergency UHF channel for delivering alarms and critical notifications
- SOS button, 2G / 3G / 4G (LTE), pLTE and MCPTT for priority voice communication
- Electronic work permits and the RealTrac interface on the smartphone screen
- Photo capture linked to indoor coordinates
- Integration with MES / EAM / ERP via the RealTrac API
