Suffix “G2BTF”: Enhanced accuracy (G2B) + Teflon (PTFE) conformal coating (TF) + G2 wiring configuration

Key Features

Enhanced accuracy – ±0.08% for critical temperature measurements
Faster sampling – 10 Hz for responsive monitoring
G2-specific wiring configuration – unique channel-to-terminal mapping matching specific GE cabinet wiring standards; direct drop-in for G2-configured systems
Teflon (PTFE) conformal coating – superior chemical resistance (acids, bases, solvents), extreme moisture barrier, low friction surface, excellent dielectric properties, and temperature stability from -55°C to +150°C
Extended low-temperature range – operates down to -40°C for arctic or unheated cabinets
Improved cold-junction compensation – better linearization across ambient variations
Basic self-diagnostics – open-circuit and short-circuit detection per channel
Simple swap – no firmware changes required in most Mark V systems
LED status per channel + board health
Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

Chemical processing plants with G2-configured cabinets – where strong acids, bases, and aggressive solvents are present, combined with G2 wiring standards
Pharmaceutical manufacturing – cleanroom environments requiring non-contaminating, non-stick PTFE surfaces and G2-compatible wiring
Paper and pulp mills – high-moisture, high-chlorine environments with existing G2 termination
Food and beverage processing – where cleaning chemicals (chlorine, caustics) are used regularly on G2-standard systems
Coastal power plants – superior moisture barrier against salt spray in G2-wired cabinets
Laboratory and test cells – solvent vapor environments where standard coatings degrade, with G2-specific wiring needs
Turbine retrofits in corrosive areas – maintaining G2 wiring while adding PTFE protection and high accuracy

Comparison with Competitors

Selection Tips

Choose the DS200TCEAG2BTF only if your cabinet uses G2 wiring configuration AND you require high accuracy (±0.08%) AND your environment has aggressive chemicals that would degrade standard coatings – this is the most specialized combination in the TCEA series
For G2 systems with chemical exposure but where ±0.12% accuracy is acceptable, the DS200TCDAG2B with PTFE coating (if available) may be more economical
For G2 systems with chemical exposure and extreme temperature needs, consider specialized variants
For G1 systems with similar requirements, use the DS200TCEAG1BTF
Verify existing wiring pinout against G2 standard – using the wrong terminal block or miswiring will scramble channel readings

Precautions

ESD sensitive – use wrist strap; PTFE coating does not eliminate ESD risk
Power down for Mark V removal (no hot-swap)
Torque terminals to 0.5 N·m max – over-tightening cracks PCB traces
Do not exceed -40°C to +70°C operating range
Pinout critical – G2 mapping differs from G1; verify cabinet wiring before installation
PTFE coating is slippery – handle with care to avoid dropping the board
Avoid scratching the coating – PTFE can be abraded; scratches expose the PCB underneath
No rework or soldering – PTFE coating is near-impossible to remove cleanly in the field
Calibrate every 24 months – accuracy spec depends on valid calibration
Ground shields only at the board end
Verify thermocouple type – hardware optimized for J/K (T/E reduces accuracy to ±0.15%)
Label clearly – mark board and slot as “G2B TF – PTFE COATED / G2 CONFIG” to prevent future miswiring
