Analog to HART converters?

[cludwig]

I have user HART tri-loop to Analog converters supplied by Rosemount before with great success, but I now need to acquire 4-20 mA signals with a HART modem-only acquisition system. The acquisition system is capable of acquiring only the digital portion of the HART signal, not analog signals.

Has anyone heard of such a converter?

Thanks and enjoy you day.
Chris.

I need this to be a rail mount design so it will fit in my flameproof junction box. Adaptions using full transmitters won't work for me.

I have not but have you checked with B&B electronics? Their line of converters is added to on a regular basis.

Have recently used Moore Industries products. Not bad at all.
