Combining reliable technology with superior field knowledge, Yokogawa has insights into the lifecycle of the device that provides added value to the user. The YTA610 in capable of dual sensor input. With the processing capability of the transmitter, this dual input can be used to provide Failed Sensor Backup, Temperature Averaging, or Differential Temperature measurement. Industrial process control where accurate temperature measurement is required. Safety-instrumented systems (SIS) due to SIL 2 certification. Applications needing redundant or differential sensor reading (due to dual-input). Harsh environments (moisture, dust) because of rugged housing. Systems using HART or Fieldbus communications for diagnostics and remote configuration.
Accuracy & Stability
Advanced linearization for 21 types of industrial sensors.
A/D accuracy for a typical Pt100 RTD: ± 0.14 °C.
D/A (output) accuracy: ± 0.03%.
Dual-Compartment Housing
Field-mount design with two compartments: one for field wiring, another for electronics. Improves durability in harsh environments.
Housing materials: aluminum or stainless steel depending on model.
Sensor Inputs
Supports RTDs (resistance), thermocouples (T/C), ohm input, and DC millivolt signals.
Can work with single or dual sensor inputs. Dual input supports back-up, averaging, or differential measurement.
Output / Communication Protocols
4–20 mA analogue output.
Digital communication options: HART 7 or FOUNDATION™ Fieldbus (ITK 6).
Local Parameter Setting
Models with an integral indicator have push-button local parameter setting (on-site configuration).
Local display can show sensor data, diagnostic info, etc.
Diagnostics & Safety Features
Basic diagnostics: e.g., sensor failure detection.
Sensor backup: if primary sensor fails, the transmitter can automatically switch to the secondary sensor (if dual input).
Certified for SIL 2 (IEC 61508) when used for safety applications.
Reliability
Rugged construction for field use: dual-compartment housing helps protect against moisture and contamination.
Good resistance against ambient temperature changes.
Sensor Matching / Calibration
Supports “sensor matching” for RTDs: uses Callendar–Van Dusen coefficients to correct for individual sensor deviations (real RTD curve vs. standard curve).
Cold-junction compensation accuracy for thermocouples: ± 0.5°C.
Certifications & Approvals
International approvals: FM, CSA, ATEX, IECEx, INMETRO, etc.
Explosion-proof and intrinsically safe versions available.
