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. Accuracy, sensor monitoring and the permissible ambient conditions are matched to the requirements of industrial applications. The case is designed as a head-mounted transmitter for direct mounting within the temperature sensor and can be fitted to any form B DIN connection head. The transmitters in rail mounting cases are suitable for all standard rails in accordance with DIN EN 50022-35.
