As cooling systems become increasingly critical in modern AI-ready data centres, measurement accuracy has never been more important. Even small temperature deviations can affect cooling capacity calculations, increase energy consumption, create hotspots, and reduce overall system efficiency. Precision sensing therefore forms the foundation of effective thermal management and sustainable data centre operations.

Precision Engineered for Critical Applications

Acez Sensing develops and manufactures a comprehensive range of industrial temperature sensing products designed for demanding applications where accuracy, reliability and long-term stability are essential.

Our product portfolio includes:

• High Accuracy Temperature Sensors (TE25 & TE26 Series) for HVAC, chilled water systems and Cooling Distribution Units (CDUs)
• Custom RTD Temperature Sensors
• Thermocouple Sensors
• Multipoint Temperature Sensors
• Thermowells
• Sampling Probes
• Mineral Insulated Thermocouples
• RTD Elements and Probe Assemblies
• Custom-engineered temperature sensing solutions for OEM and industrial applications

Every product is engineered to deliver reliable, repeatable measurement performance while meeting the specific installation and process requirements of each application.

High Accuracy Temperature Sensors for Data Centres

Among the Acez Sensing product range, the TE25 and TE26 High Accuracy Temperature Sensors are specifically developed to support mission-critical cooling systems in modern data centres.

Engineered for Cooling Distribution Units (CDUs), chilled water systems, CRAH/CRAC units and precision HVAC applications, these sensors provide exceptional measurement performance where every fraction of a degree directly influences cooling efficiency and energy optimisation.

The TE25 and TE26 are available with multiple sensing technologies to suit different engineering requirements:

• Platinum RTD Pt100 (Class 1/10 DIN) with calibrated system accuracy of up to ±0.03°C
• Platinum RTD Pt1000 (Class 1/10 DIN) offering superior signal resolution with the same ±0.03°C calibrated system accuracy
• High-Accuracy 10kΩ NTC Thermistor with ±0.05°C tolerance between 0°C and 50°C, providing rapid response and excellent sensitivity within chilled water operating temperatures

Unlike standard off-the-shelf sensors, Acez Sensing offers customised probe lengths, thermowells, process connections, cable configurations and mounting arrangements to ensure optimum immersion depth and accurate pipe core temperature measurement while minimising thermal conduction errors.

When paired with the Blue Gizmo BG38PT Precision Thermometer, the complete calibrated measurement system achieves a combined measurement accuracy of up to ±0.03°C, providing consultants with the confidence required for commissioning, Measurement & Verification (M&V), chilled water heat balancing and compliance with Singapore SS591:2021.

Supporting Smarter and More Sustainable Data Centres

Accurate sensing enables better engineering decisions.

With precise temperature data, consultants and facility operators can:

• Verify chilled water cooling performance with greater confidence
• Improve heat balancing across cooling systems
• Detect low ΔT syndrome and inefficient heat transfer
• Optimise chiller and pumping efficiency
• Reduce unnecessary overcooling and energy consumption
• Improve equipment reliability and operational resilience
• Support Measurement & Verification (M&V) and SS591 compliance
• Contribute to ESG and sustainability objectives through lower carbon emissions

As data centres strive to reduce Power Usage Effectiveness (PUE) and improve overall energy performance, high-accuracy sensing has become a key enabler of intelligent cooling optimisation.

Manufactured with Confidence

As the manufacturing division of Acez Instruments, Acez Sensing combines engineering expertise with precision manufacturing capabilities to deliver customised sensing solutions for OEMs, consultants, contractors and system integrators.

To ensure confidence in every measurement, Acez Sensing temperature sensors can be supplied with ISO/IEC 17025 traceable calibration, providing internationally recognised measurement traceability, reduced uncertainty and long-term measurement reliability throughout the product lifecycle.

Whether for standard applications or fully customised designs, every sensing solution is developed to meet demanding industrial performance requirements while supporting accurate monitoring, process optimisation and regulatory compliance.

Precision Sensing for the Future

As AI computing, high-density racks and liquid cooling technologies continue to reshape the data centre industry, the demand for more accurate, reliable and intelligent sensing solutions will only increase.

Acez Sensing remains committed to advancing precision temperature measurement through innovative sensor design, custom manufacturing and engineering excellence, empowering customers to build smarter, more reliable and more sustainable critical infrastructure.
