The analogue transmitters of the T19 series feature configurable measuring ranges and are intended to be used with resistance thermometers. Via the simple setting of solder bridges, one of several defined measuring ranges can be selected. These transmitters are therefore particularly suitable for users who need to respond quickly to changing requirements. The temperature transmitters convert temperature-dependent resistance from the resistance thermometers into a 4 ... 20 mA current loop signal. Thus the measured temperature values can be transmitted securely and simply.
