648 Wireless Temperature Transmitter

Rosemount™ 648 Wireless Temperature Transmitter (Emerson Original New)

The Rosemount 648 is Emerson's flagship WirelessHART temperature transmitter, designed for hard-to-wire process points, eliminate thermowell drilling, pipe penetration and potential leakage points with exclusive X-well™ thermal conductivity algorithm technology.

Perfect for oil & gas, refinery, power plant, chemical plant, pulp & paper, offshore platform. No field cable laying, drastically cut installation cost by 60% compared with wired transmitters.

100% genuine Emerson original new, full factory test report, DD/EDD files for AMS Trex, complete calibration document, 12 months full warranty.

✅Exclusive X-well™ Non-Intrusive Measurement

Work with 0085 pipe clamp sensor, calculate media temperature by pipe surface + ambient temperature, no process tapping, no thermowell required, eliminate leakage risk.

✅ Stable WirelessHART IEC Standard Protocol

Industrial grade mesh network, data reliability >99%, fully compatible with Emerson 1420 wireless gateway, AMS Trex communicator, DeltaV DCS system.

✅ Universal Input
