The 4-20mA R A-Link is a single-channel, long-range wireless 4-20mA receiver that is ideal for industrial processes, environmental monitoring, and water and wastewater applications. This device allows for reliable two-way communication and is designed to provide accurate and consistent data transmission.
How Smartrek 4-20mA Receiver A-Link Works:
A 4-20mA receiver is designed to receive signals in the form of a 4-20mA current loop from a transmitter. The 4-20mA current loop is a closed loop system, meaning the signal is sent from the transmitter to the receiver and then back to the transmitter, much like a circuit. The transmitter’s current signal is proportional to the signal it is trying to measure. The receiver measures the current and converts it into a readable signal by a computer or other device. In this way, the receiver can be used to monitor and control a process.
