Belimo 01CT-5QH01 Sensor
The Belimo 01CT-5QH01 is a high-precision NTC10k2 passive temperature sensor designed for accurate thermal monitoring in corrosive HVACR environments. This cable temperature sensor features a 2-inch (50mm) stainless steel probe and a 201-grade stainless steel sensing element, providing excellent moisture resistance and thermal conductivity. With its IP67/NEMA 4X rated encapsulation, it is purpose-built for discharge air temperature monitoring, coil sensing, and fluid temperature measurement in closed-loop hydronic systems. The unit comes equipped with a 2-meter (6.5 ft) PVC cable, ensuring flexible installation for remote mounting requirements. Integration is seamless across major building automation systems (BAS), as the 01CT-5QH01 thermistor provides stable resistance output with minimal drift over time. This sensor is an essential component for contractors requiring reliable HVAC temperature sensors that maintain signal integrity in high-humidity applications or air handling unit (AHU) compartments.
Key Benefits for Technicians- Universal Compatibility: The 10k Ohm Type II thermistor curve matches standard industry controllers, ensuring accurate logic for PID loops.
- Industrial Durability: The IP67 protection class and dual-layer encapsulation prevent moisture ingress, common in plenum-rated environments.
- Precision Response: Optimized 50mm probe length allows for better immersion depth in smaller diameter piping or air ducts without causing significant pressure drops.
- Simplified Wiring: The pre-stripped 2-wire 2m cable lead reduces field labor during point-to-point terminations.
Is the 01CT-5QH01 suitable for immersion in high-pressure lines?
Yes, but it must be paired with an appropriate thermowell for direct fluid contact to prevent probe fatigue and ensure long-term hermetic sealing.
What is the operating temperature range for the cable lead?
While the probe is rated for broader extremes, the PVC cable remains flexible and stable between -35°C to +80°C (-30°F to +176°F).
Does this sensor require calibration upon installation?
The Belimo 01CT-5QH01 is factory-calibrated to high tolerances, but field verification of resistance vs. temperature (R/T) values is recommended to account for any long-run cable resistance offsets.
