Rosemount 848T High Density Temperature Transmitter

The Rosemount 848T is Emerson's flagship high-density multi-point temperature transmitter, split into two versions: FOUNDATION Fieldbus wired model (8 channels) and WirelessHART wireless model (4 channels).

Each unit supports independent configuration of multiple sensor signals, drastically cutting cable, labor and cabinet space for multi-point temperature monitoring. Built-in measurement validation diagnostics, hazardous area global certifications, match perfectly with Rosemount 214C sensors & 114C thermowells for complete temperature measurement systems.

1. Multi-channel high-density measurement

Wired version: 8 isolated independent channels; Wireless version: 4 channels. Compatible with 2/3/4-wire Pt100 RTD, all types thermocouple, mV, ohm, 4-20mA analog input. Single device replaces multiple single-point transmitters, reduce wiring cost by over 60%.

2. Channel-to-channel isolation 600V DC

Strong anti-interference, avoid signal crosstalk in dense instrument layout, stable reading for distillation column, reactor multi-layer temperature monitoring.

3. Intelligent self-diagnosis system

Auto detect sensor burnout, line break, abnormal temperature drift; 8 configurable process alarms, early warning to prevent unplanned plant shutdowns.

4. Dual communication options

• Wired 848T: FOUNDATION Fieldbus bus-powered, one bus cable for 8 measuring points

• Wireless 848T: WirelessHART, no field wiring, SmartPower battery up to 10 years service life

5. Rugged & explosion-proof certified

IP66 / NEMA 4X housing, aluminum / stainless steel junction box; ATEX, IECEx, FM, CSA intrinsically safe certifications, suit oil & gas, chemical hazardous zones.

6. Easy commissioning & maintenance

Support 475 / Trex HART communicator one-click configuration; device dashboard visual data viewing, simplify troubleshooting and calibration.

7. Long-term stable accuracy

Pt100 accuracy ±0.3°C, 2-year stability; thermocouple ±0.7°C, 1-year stability, meet pharmaceutical SIP sterilization precision requirements.

• Oil & Gas: Tank layered temperature monitoring, refinery distillation column, furnace multi-point temperature

• Chemical Industry: Reactor, heat exchanger, pipeline dense temperature measuring

• Biopharmaceutical: SIP sterilization continuous temperature monitoring, F0 value automatic calculation, shorten production cycle

• Power Plant: Turbine bearing, pump, compressor equipment temperature monitoring

• Food & Beverage: Sterilization tank, fermentation tank multi-point temperature control

• Environmental Protection: Waste water, flue gas temperature monitoring

• Rosemount 214C thermocouple / RTD temperature sensor

• 114C / 114P thermowell for corrosion & high temperature protection

• Trex HART communicator (replace obsolete 475 hand-held communicator)

• Stainless steel junction box, installation pipe bracket, lightning surge protection module

Lots of low-cost imitation 848T transmitters circulate in the market. Clone products have hidden risks:

1. Poor circuit isolation, severe signal interference, inaccurate temperature reading leading to production failure

2. Fake explosion-proof certification, huge safety hazard in flammable & explosive working conditions

3. Short service life, frequent drift, high maintenance cost in long run

4. No official calibration support, no after-sales warranty

We supply 100% original Emerson Rosemount 848T with complete factory certificate, test report, full after-sales technical support.

Q1: What's the difference between wired 848T and wireless 848T?

A: Wired model adopts FOUNDATION Fieldbus, 8 measuring channels, bus power supply; Wireless version uses WirelessHART, 4 channels, battery-powered, no field wiring required.

Q2: Can 848T work with all Rosemount temperature sensors?

A: Yes, perfectly matched with 214C series RTD & thermocouple, cooperate with 114 series thermowell for complete temperature measuring system.

Q3: Is the transmitter suitable for hazardous explosive areas?

A: Yes, with full set ATEX/IECEx/FM intrinsic safe certificates, can be installed in Zone 0/1/2 hazardous locations.
