• Weight: 0.6 kg (1.3 lb)

Functional Features:

• HART 7 communication for remote configuration via handheld or DCS
• Two-wire loop power — no separate power supply needed
• Sensor fault detection (open circuit, short circuit, out-of-range)
• Programmable damping: 0.5–32 seconds
• Reverse polarity protection

Performance Parameters:

• Linearity: ±0.05% of span
• Hysteresis: ±0.03% of span
• Long-Term Drift: ±0.05% of span per year
• Input Impedance (RTD): 100 Ω (2-wire)
• Output Load: 200–1200 Ω

Structural Features:

• Compact 316L stainless steel housing
• 1/2″ NPT process connection (bottom-mounted)
• PG9 cable gland with O-ring seal
• 4-button HART interface on top (or via HART communicator)
• DIN rail clip optional (separate accessory)

Working Principle:
The transmitter applies a precise excitation current to the Pt100 RTD and measures the resulting voltage drop. The resistance is converted to temperature using the Callendar-Van Dusen equation. The microprocessor linearizes the signal, applies damping, and outputs a 4–20 mA signal proportional to temperature. HART communication superimposes digital data on the 4–20 mA signal.

Key Advantages:

• ±0.1°C accuracy without field calibration
• HART 7 enables remote diagnostics — reduces site visits
• NEMA 4X / IP67 rating for harsh environments
• 2-wire RTD simplifies wiring in existing installations

Applicable Industries: Oil and gas, power generation, chemical processing, food and beverage, pharmaceutical, water treatment

Installation Requirements:

• Mount in thermowell with immersion depth ≥ 10× sheath diameter
• Use 3-wire or 4-wire RTD for best accuracy (2-wire has lead resistance error)
• Loop resistance: 200–1200 Ω at 24 VDC
• Torque process connection to 30 N·m

Usage Notes:

• Perform HART configuration using Rosemount 475 Field Communicator or AMS Suite
• Recalibrate every 2 years or per SIL requirement
• Do not exceed 42 VDC supply voltage
• Replace O-ring on cable gland annually in corrosive service
