STT750 Temperature Transmitters are suitable for a wide range of control and safety applications, the transmitters provide users with the benefits of the SmartLine platform, including modularity, easier maintenance and lower total cost of ownership
Well-suited for industrial process control where precision and stability are needed. Good choice for safety instrumented systems given its SIL 2/3 compliance. Useful in environments with electrical noise, thanks to galvanic isolation. Because of it’s modular design, it’s cost-effective in maintenance-heavy setups (easy to swap modules). High isolation voltage (e.g., 2000 VDC between input, output, and ground) for noise protection. Polarity-insensitive 2-wire loop allows flexibility in wiring
Digital accuracy up to ± 0.14 °C for RTD inputs.
Long-term stability: ± 0.01% of upper range limit (URL) per year, for up to 10 years.
~125 ms update time for single‐input models.
~250 ms for dual-input variants.
Supports a wide variety of sensors: RTD, thermocouple, mV, and resistance (ohm).
Some models support dual-sensor input (for redundancy, averaging, or differential measurement).
Built-in galvanic isolation to reduce noise.
Dual-compartment housing separates electronics/display from wiring.
Sensor break detection to detect open/failed sensor.
Comprehensive on-board diagnostics to monitor health of transmitter and sensor.
Compliant with SIL 2 / SIL 3 for safety instrumented systems.
Supports NAMUR 89 wire break detection.
4–20 mA analog output.
HART 7 communication for digital configuration / monitoring.
Modular alphanumeric LCD display (optional, field replaceable).
Display can be rotated (0°, 90°, 180°, 270°) for optimal viewing.
Supports up to 8 configurable display screens on basic LCD.
Integral three-button configuration (zero, span, setup) + optional external buttons.
Support for entering Callendar–Van Dusen coefficients (R0, α, β, δ) for calibrated RTDs.
Modular design: electronics, temperature board, display, and communication modules can be swapped without losing calibration or performance.
Polarity-insensitive loop wiring (works even if wiring is reversed).
Hazardous-area approvals: FM, CSA, ATEX, IECEx.
EMI / EMC: complies with relevant standards per model.
Warranty: up to 3 years
