This system is composed by a transmitter and gateway, which is connected via MODBUS RTU to a PLC, SCADA, PC, HMI or by the replication of 8 analogue outputs, through a direct controller connection. PLUS wireless system was designed to monitor 4..20 mA / 0..10V signals, providing a secure communication, without cable requirements of a complex wired solution. Conductivity, PH, vibration, humidity, flow, level, pressure and temperature are some examples of industrial process variables, possible to be monitored and controlled.
