Carrier 30GT412176 Temperature Sensor

The Carrier 30GT412176 Temperature Sensor is a critical OEM replacement component engineered for high-precision thermal monitoring in commercial HVAC systems. Designed specifically for integration with the Carrier 30GT Chiller series and compatible packaged units, this thermistor-style HVAC temperature sensor provides accurate resistance feedback to the main control board, ensuring optimal refrigerant cycle management and head pressure control. With a measurement range spanning -40°F to 250°F, it delivers the high-fidelity data required for maintaining setpoint stability in demanding industrial environments.

Constructed with a 12.5-inch lead for flexible routing, this factory authorized part ensures a seamless electrical interface without the impedance issues common in aftermarket alternatives. For technicians, installing a genuine Carrier 30GT spare part like the 30GT412176 is essential for preventing sensor-drift-related alarms and maximizing the operational efficiency of large-scale chiller temperature control systems. This robust sensor is built to withstand thermal cycling and moisture ingress, maintaining reliable 0-10V DC or 4-20 mA output signals depending on your specific controller configuration.

Key Benefits

• Optimized Compatibility: Replaces 30GT412176 exactly, ensuring no-splice installation and perfect fitment within the thermowell.
• High Precision Monitoring: Provides accurate temperature measurement with ±0.5°F tolerance for tighter system control loop responsiveness.
• Industrial-Grade Durability: Engineered to handle the vibrations and temperature extremes found in Carrier 30GT air-cooled chillers.
• Enhanced System Efficiency: Reliable feedback prevents unnecessary compressor cycling, reducing energy consumption and mechanical wear.

Common Questions

What are the symptoms of a failing 30GT412176 sensor?
Technicians typically observe "out of range" error codes, inconsistent suction or discharge readings, or the system failing to initiate a cooling stage due to faulty ambient or fluid temperature data.

Is this sensor compatible with 3-wire configurations?
Yes, the Carrier 30GT412176 supports both 2-wire and 3-wire interfaces, making it adaptable to various Carrier equipment control logic requirements.

Can I use a universal thermistor instead of this OEM part?
While universal parts exist, the specific resistance curve of the 30GT412176 is calibrated for Carrier’s proprietary algorithms. Using an unapproved alternative can lead to system-wide calibration errors and decreased efficiency.
