Javelin 4-20mA Transmitter - Define Instruments Video
The Javelin is a loop powered, isolated transmitter with options to suit a virtually endless range of industries. High quality signal conditioning is a popular application. Another widely used application is as a simple 4–20mA in, and 4–20mA out isolator, to protect inputs of PLC's and SCADA systems from ground loops, transients, and the effects of EMC. The Javelin can also be used to convert other standard process signals (such as ±10V, 1–5V, and 0–10V) to a 4–20mA signal. More sophisticated applications are also catered to. For example, a level signal from an odd shaped tank can be converted to a 4–20mA signal representing volume, by using the in-built linearization table.
