The TEMP-WM y TEMP-DM temperature transmitters include high-accuracy, highly stable sensors for temperature measurement. Measured values are converted into 4 to 20 mA output signals linearly related to the reading. Optionally, a 0 to 10 Vdc voltage output is available.
These microprocessor-based units can be fully configured using the TxConfig communication interface and the Windows® operating system.
The TEMP-WM model is intended for wall mounting, and the TEMP-DM model has an extended sensor sheath for duct or through-wall mounting.
– Pt100 sensor input: configurable
