1. What sensors are compatible with the Rosemount 248 transmitter?

It supports universal industrial inputs, including all standard RTDs, thermocouples, mV and resistance signals. It fits almost all common industrial temperature sensors.

2. Which version should I choose, HART or WirelessHART?

The wired 4-20mA HART version is more stable and cost-effective for wired field sites. The WirelessHART version is ideal for distributed devices and sites with difficult wiring conditions.

3. Does the 248 transmitter support remote configuration?

Yes. Users can remotely adjust measurement range, modify parameters, read real-time temperature data and view device diagnosis status via HART handheld communicator or system software.

4. Can it work in harsh industrial environments?

Absolutely. With wide temperature tolerance, moisture resistance and high voltage isolation design, the Rosemount 248 transmitter performs steadily in high temperature, low temperature, humid and strong interference industrial working conditions.
