4-20mA Transmitter:

The 4-20mA T A-Link is a single-channel, long-range wireless 4-20mA transmitter that is ideal for industrial processes, municipal, agricultural, automation, water and wastewater applications, and much more. It is compatible with any machine or controller, such as PLCs, SCADA systems, and drives

How Smartrek 4-20mA Transmitter A-Link Works:

A 4-20mA Transmitter is used to measure and transmit electrical signals over long distances. It works by measuring an analog signal from a sensor or other device and then converting it into a 4-20mA current loop signal. The 4-20mA signal provides a highly accurate and reliable way to measure and transmit analog signals from sensors or other devices.
