MS190 is a smart 2-wire transmitter which can be programmed via a PC .It has measurement input for resistance thermometers (PT100)  in 2-, 3- or 4-wire connection, and converts the input signal into a standard 4 to 20 mA analog output signal after linear processing. The measuring temperature can be displayed by a high luminance LED or LCD directly, which depends on the user’s requirement.

MS190 is housed in an aluminum alloy or engineering plastic casing which are made in China to protect it from dust and water.
