Key Features

Enhanced accuracy – ±0.08% for high-precision temperature monitoring
Faster sampling – 10 Hz for responsive monitoring compared to standard G1 series
Improved cold-junction compensation – stable readings across ambient temperature 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
Standard conformal coating for moisture/dust resistance
Backward compatible with Mark V and Mark VIe (hot-swap only on VIe Rev D+)

Applications

Gas turbine EGT monitoring – tighter accuracy improves combustion control and thermal efficiency
Steam turbine bearing and casing temperatures – critical protection with precision measurements
Generator stator cooling monitoring – accurate over-temperature detection
HRSG temperature measurements – improved thermal efficiency tracking
Compressor performance monitoring – precision data for performance optimization

Comparison with Competitors

Selection Tips

Choose the DS200TCPAG1A if you need enhanced accuracy (±0.08%) and faster sampling (10 Hz) with G1 wiring
For basic monitoring where ±0.12% is acceptable, the DS200TCEBG1 is more economical
For the same accuracy with extended temperature range, consider DS200TCEAG1B
For advanced diagnostics (drift/degradation), consider DS200TCDAG1ADA
Verify existing wiring is 2-wire standard – G1-series terminal mapping applies
Source refurbished units with accuracy verification in test report

Precautions

ESD sensitive – use wrist strap
Power down for Mark V removal (no hot-swap)
Torque terminals to 0.5 N·m max
Do not exceed -30°C to +65°C operating range
Calibrate every 24 months – accuracy spec depends on valid calibration
Ground shields only at the board end
Verify thermocouple type – optimized for J/K (T/E reduces accuracy to ±0.15%)
Label clearly – mark as “G1A PRECISION” to distinguish from lower-accuracy boards
