This CTS Pressure Sensor, model CTSPS5311275SP, is a core component for monitoring refrigerant pressures within your HVAC or refrigeration system. It's built to provide accurate feedback, helping service techs keep an eye on system health and troubleshoot issues quickly. Keeping your sensors in good nick prevents major headaches down the line, especially during those scorching Australian summers when systems are working hardest.

A faulty pressure sensor can lead to incorrect readings, causing a unit to cycle improperly, run inefficiently, or even trip out on high or low pressure. Swapping out a tired sensor with a reliable replacement like this one is a smart move for system longevity and efficiency.

Best For

• HVAC service and maintenance technicians
• Refrigeration mechanics
• Apprentices learning system diagnostics
• Competent DIY owners replacing existing sensors

Compatibility

The CTSPS5311275SP is designed as a direct replacement pressure sensor for a range of HVAC and refrigeration systems where the original sensor matches its electrical and physical specifications. It’s suitable for use with common refrigerants like R410A, R32, and R134a, provided the system pressures are within typical operating limits for this class of sensor. If you're running a different model, check fittings and specs before ordering.

Features

• Accurate Pressure Monitoring: Provides reliable pressure readings crucial for system control and diagnostics.
• Durable Construction: Engineered to withstand typical HVAC operational environments and vibration.
• Direct Fit Replacement: Designed for easy installation, minimising downtime during service.
• Broad Refrigerant Compatibility: Suitable for modern refrigerants in common use.

What's in the Box

• 1 x CTS HVAC System Pressure Sensor (CTSPS5311275SP)
• Basic installation guide

Using It on the Job

1. Isolate Power: Always disconnect and lock out power to the unit before commencing any work.
2. Recover Refrigerant: If the sensor is connected to a live refrigerant circuit, recover all refrigerant from that section of the system using an ARCtick approved recovery unit.
3. Depressurise & Remove: Once depressurised, carefully disconnect the old sensor. Be mindful of any residual oil or refrigerant.
4. Install New Sensor: Apply a thread sealant suitable for refrigerants (if not pre-applied) and gently thread the new CTSPS5311275SP sensor into place. Torque to manufacturer's specifications.
5. Evacuate & Charge: Evacuate the relevant section of the system to a deep vacuum (e.g., 500 microns) and then recharge with the correct type and amount of refrigerant.
6. Test Functionality: Restore power and test the system, verifying the new sensor provides accurate readings on your manifold gauges or system display.

Limitations & Safety Notes

• Only use this sensor on compatible systems and refrigerants as per the manufacturer's specifications for the overall unit.
• Working with refrigerants requires a current ARCtick licence in Australia. Always adhere to industry best practices.
• Ensure proper system depressurisation before removing or installing, to prevent refrigerant release or injury.
• Always follow Australian standards and Safe Work guidance when performing HVAC maintenance.

When fitting any sensor, make sure the system is clean and free of debris. A bit of dirt in the port can throw off readings or even damage the new component. Double-check your connections for leaks before pressurising.

Pair With

Pair this pressure sensor with digital manifold gauges for accurate diagnostics and a quality vacuum pump to ensure proper system evacuation. Consider adding a set of flare nut wrenches for secure, leak-free connections.
