Analog Bridge
The AnalogBridge system has been designed to provide reliable remote monitoring and alarm functions for various types of continuous level instruments such as...
-
Remote Level Monitoring for Dams, Reservoirs, Water and sewerage tanks,Slurry pits for mines etc
-
Voltage monitoring of remote equipment from solar powered, DC powered or mains powered equipment or processes
-
Current such as 4-20mA loop powered sensors, motor current etc
-
Wireless Temperature monitoring such as ambient temperature, bearing temperature on conveyor systems, remote monitoring of cool rooms and computer rooms etc
-
Remote Water pressure and water flow monitoring
The remote end of the AnalogBridge system comprises 2 Analog inputs that can be configured as 4-20mA, 0-2.5V, 0-5V or 0-10V DC. The unit provides a continuous 5VDC supply and a switched 12V/24V DC supply for applying powered to external sensors only when readings are required.
The remote transmitter unit has a very low average current consumption and has a built-in power supply voltage monitoring circuit which make it suitable for battery powered or solar powered applications.
The receiving unit has 2 Analog outputs that generate 4-20mA loop current that represents the levels of the inputs at the transmitter unit. By placing a resistor across the outputs a voltage output 0-2.5, 0-5 or 0-10V DC can be generated.
The over-air communications is monitored and a local alarm is activated if the transmitter supply voltage becomes too low or there is any fault with the radio telemetry link. An optional GSM alarm is also available to send a text alarm message directly to your mobile phone if there is a communications link fault, low supply voltage or the inputs go above or below user-programmable trip points.
Both transmitter unit and receiver unit can be powered by 12/24V DC or AC. The units are available in IP65 water-proof and dust-proof enclosures. (Low profile "ID" version for installation out of direct sunlight, "OD" version that is UV stable and has room for solar regulator and backup battery (7AHr).
