Faedah dan Kelebihan Utama
Flexible Mounting Configurations: Unlike many transmitters that are restricted to a single form factor, the STT700 is available in multiple mounting options to suit any plant layout:
-
Head Mount: Fits directly into DIN Form B sensor heads.
-
Field Mount: Housed in rugged Aluminum or Stainless Steel enclosures for pipe mounting.
-
DIN Rail & Panel Mount: Ideal for high-density cabinet installations.
Advanced Sensor Support: The STT700 supports a single input for 4-wire RTDs, ensuring maximum lead-wire compensation. For applications requiring redundancy or differential measurement, a dual-input option is available that supports two independent 3-wire RTD connections.
Callendar-Van Dusen Sensor Matching: To achieve the highest possible system accuracy, the STT700 allows users to input specific Callendar-Van Dusen constants from a calibrated RTD. This process “matches” the transmitter to the unique curve of the sensor, effectively eliminating inherent sensor error.
SmartLine Connection Advantage: When integrated with Honeywell’s Experion PKS, the STT700 offers enhanced visibility. This includes “Connection Advantage” features that streamline commissioning and provide advanced loop health data directly to the control room, reducing the time spent on field troubleshooting.
Safety Instrumented Systems (SIS): Every STT700 is designed for high-reliability environments and is fully compliant with SIL 2/3 requirements. This makes it an ideal choice for emergency shutdown loops and critical temperature monitoring in volatile process zones.
Comprehensive Communication: The transmitter supports both HART 7 and Honeywell’s Digitally Enhanced (DE) protocols, ensuring compatibility with both modern and legacy control systems.
