Tips: What is a 4 20 milliamp signal generator?

A 4-20 milliamp (mA) signal generator is a device designed to produce an electrical current signal within the range of 4 to 20 milliamps. This type of signal is commonly used in industrial applications for process control and monitoring. The 4-20mA signal is popular in industrial instrumentation because it provides a standardized, reliable, and low-noise method of transmitting analog signals over long distances.

The signal generated by a 4-20mA signal generator is often used to represent a measurement or a control setpoint. For example, sensors like pressure transducers, temperature sensors, and level sensors might output a 4-20mA signal proportional to the measured parameter. Similarly, the 4-20mA signal can be used to control devices such as valves or motor drives.

The key advantage of the 4-20mA signal is its ability to provide accurate and stable data transmission over relatively long distances without significant signal degradation or susceptibility to interference. This makes it well-suited for industrial environments where precise control and monitoring are crucial.

Builder in Product TAB

NEW! Since Journal 3.2, the much improved T.A.B (Tabs Accordion Blocks) system supports the page builder inside the tab content. Unlimited Blocks, Tabs or Accordions with any HTML content or the builder interface (supporting custom rows/columns/modules) can be assigned to any individual product or to certain groups of products, like entire categories, brands, products with specific options, attributes, price range, etc. You can indicate any criteria via the advanced product assignment mechanism and only those products matching your criteria will display the modules. Also, any module can be selectively activated per device (desktop/tablet/phone), customer login status and other criteria. Imagine the possibilities.
