IN Brief:
- CTS has added its first digital temperature sensing platform to its established temperature sensor portfolio.
- Current devices provide 16-bit measurement with up to ±0.1°C accuracy across the central operating range.
- Probe, cable, and housing options target applications from industrial automation and batteries to medical equipment and energy systems.
CTS Corporation has introduced its first digital temperature sensor platform, adding integrated digital measurement to its existing temperature sensing portfolio. The range is intended for industrial, medical, transportation, and electronics applications, with several probe and housing configurations designed to place precision temperature measurement directly at the point of interest.
The platform combines the sensing element with signal conditioning, analogue-to-digital conversion, and a digital output, reducing the amount of external measurement circuitry required between the probe and the host system. CTS is offering multiple mechanical configurations rather than a single fixed package, allowing the same basic sensing approach to be adapted to equipment with different installation, cable, and environmental requirements.
Current product information specifies an operating range from -55°C to +150°C. CTS quotes maximum accuracy of ±0.1°C between -20°C and +50°C and ±0.3°C across the wider -55°C to +150°C range, with a 16-bit temperature result providing 0.0078°C resolution. The devices operate from a 1.8V to 5.5V supply and provide programmable temperature alert limits.
Those specifications put the platform beyond simple over-temperature protection. A digital temperature channel can be incorporated into monitoring and control functions where the actual measured value is used to adjust cooling, power, charge rates, equipment loading, or maintenance decisions rather than merely trigger a fixed thermal cut-out.
The digital architecture also changes where measurement errors enter the system. With a conventional analogue temperature probe, the sensing element may feed external amplification, filtering, conversion, and calibration circuitry, each of which contributes its own tolerance and susceptibility to electrical interference. Integrating more of that chain into the sensor assembly can simplify the interface between the measurement point and the controller.
CTS identifies standard digital interfaces including I²C, SPI, and 1-Wire across its broader digital temperature sensing approach. Individual configurations still have to be checked against their own electrical specifications, rather than assuming every probe supports each interface, but the principle is to deliver temperature data directly into modern embedded control architectures rather than requiring a dedicated analogue measurement channel.
The industrial applications are particularly broad. Battery systems, automated machinery, power equipment, HVAC installations, energy production, and other thermally sensitive assets can use local temperature measurements for control, protection, and condition monitoring. In an industrial battery installation, for example, temperature can influence charge and discharge limits as well as provide evidence of abnormal cell or connection behaviour.
Medical systems place greater emphasis on measurement accuracy, repeatability, traceability, and physical probe design. CTS lists body-temperature monitoring, incubators, medical wearables, and related equipment among the potential applications. A configurable probe architecture gives equipment designers scope to alter the mechanical interface while retaining a common digital measurement approach elsewhere in the system.
Transport applications present a different combination of constraints. Engine compartments, electric powertrains, battery packs, cabins, and auxiliary systems can all require distributed thermal monitoring, but the sensor assembly may also be exposed to vibration, electrical noise, wide ambient temperatures, and lengthy cable runs. Moving conversion closer to the sensing point can reduce the amount of low-level analogue signalling that has to travel through that environment.
The platform is also relevant to higher-density electronics, where processors, power converters, and communications hardware are increasingly managed through closed-loop thermal control. Real-time temperature data can be used to adjust fan or pump speeds, apply power derating, or identify a cooling problem before the equipment reaches a shutdown threshold. In those applications, measurement accuracy has to be considered alongside response time and the thermal path between the component being monitored and the probe itself.
CTS offers configurable probe housings and cable options rather than treating the sensing IC as the complete product. That is important because the electrical specification of a temperature sensor does not by itself establish measurement accuracy in the finished system. Placement, contact pressure, housing material, thermal mass, airflow, and insulation can all change how quickly and accurately the probe tracks the temperature engineers actually need to know.
The launch therefore gives CTS a more integrated route into equipment where temperature data is already part of the digital control system. Its practical value will depend on matching the probe construction and interface to the application, but the company is moving beyond a standalone temperature-sensitive element towards a calibrated measurement assembly that can connect directly into embedded monitoring and control architectures.
