The HollySys AW200 RTD Temperature Transmitter PT100 RTD Sensor delivers robust precision for critical industrial processes by converting resistance inputs into stable 4-to-20 mA current outputs. Backed by extensive local component inventory, Beijing Zhongping Technology ensures seamless procurement for automated plant expansions and urgent maintenance cycles.
Deploying high-density temperature measurement architectures across modern process industries frequently exposes vulnerabilities regarding signal distortion and thermal drift. When engineers must monitor extreme thermal fluctuations within confined skid boundaries, legacy transmitters often introduce electromagnetic interference or conversion inaccuracies. The AW200 series temperature transmitter modules resolve these challenges through proprietary microprocessors and high-resolution analog-to-digital conversion algorithms. Operating within the I/O control layer of distributed control systems, this unit conditions raw thermal signals directly at the sensor terminal before routing long-distance loops to control cabinets. By isolating field-induced noise and offering native HART communication protocols on the AW2001 variant, the hardware maintains superior loop integrity. This engineering approach eliminates common data dropouts and guarantees dependable real-time feedback for critical loop controllers.

System Integration and Hardware Setup
Integrating the transmitter into an existing control loop requires careful handling of field wiring and terminal shielding to prevent ground loops. Technicians must connect twisted-pair shielded cables to the designated input terminals, ensuring the shield connects to earth ground exclusively at the control cabinet side. The AW200 series features reverse polarity protection on its power supply inputs, safeguarding internal circuitry against accidental wiring errors during installation. When configuring the AW201 model, engineers can select internal or external cold junction compensation depending on the thermocouple type deployed in the process loop. The AW202 variant incorporates a direct USB interface port, allowing technicians to configure measurement ranges, damping values, and calibration trims locally using compatible software packages without disconnecting the primary 4-to-20 mA loop wires.
Reliability and Environmental Durability
Designed for deployment in harsh industrial environments, the transmitter features rigorous electrical isolation between input and output channels to block high-voltage transients. The enclosure and internal potting withstand continuous vibration from nearby pumps and compressors, preventing mechanical fatigue on surface-mounted components. Operating safely within explosive atmospheres, the unit carries dual intrinsic safety ratings for gas and dust hazardous locations. Comprehensive self-diagnostic routines constantly monitor sensor break conditions, memory checksums, and internal power supply voltages, reporting anomalies through the analog loop or digital HART stream before catastrophic measurement failures occur.
Selection Guidance and Alternative Options
Selecting the appropriate variant depends on loop communication requirements and power supply constraints available in the field panel. For standard analog monitoring loops requiring basic two-wire configuration, the AW2002 model provides a cost-effective 4-to-20 mA output paired with USB setup flexibility. When advanced digital diagnostics, multi-variable monitoring, and HART protocol integration are mandatory, the AW2001 serves as the optimal choice. Beijing Zhongping Technology maintains a comprehensive stock of both models alongside legacy spare parts, ensuring that technical specialists can assist clients with rapid cross-reference selection and direct hardware replacements.
