The 1# cable is the pipeline lead line, connected to the intelligent test post, used to measure the pipeline protection potential, power off potential, corrosion current.

(2) 2# and 3# cables are magnesium or zinc anode cables and are connected to the intelligent test post. Cables 1# and 2# and 3# are usually overlapped.

③ The 4# cable is the cable of the long-acting reference electrode, which is connected to the intelligent test post and serves as the long-term reference ground for potential measurement.

φ 108mm(diameter)*3000mm(height).

(2) Main functions

◆ Data collection: the data of cathodic protection parameters, battery voltage and measurement point signal quality are collected automatically.

Wireless communication: use 4G (Mobile/Unicom/Telecom) or NB-iot wireless network to report monitoring data regularly.

Data storage: the machine circulates to store the monitoring data, without loss in power failure.

◆ Abnormal alarm: If the potential/current exceeds the standard or the battery voltage is too low, an alarm is reported immediately.

Equipment protection: the cathodic protection circuit and all kinds of cables are protected to ensure the safety of equipment and convenient maintenance.

(3) Product features

High level of protection: waterproof, moisture-proof, dustproof.

Wide working temperature range: low temperature resistance, heat resistance.
