When space is limited, how can efficient temperature measurement be achieved? The compact straight-tube PT1000 sensor brings smart measurement to life in compact spaces.

JENNIE | 2025-10-30
In modern industry and smart devices, space is becoming a luxury. Whether in precision instruments, aerospace equipment, or thermal management systems for new energy vehicles, designers face a common challenge: When space is limited, how can efficient temperature measurement be achieved?
The answer lies in a small yet powerful device — the compact straight-tube PT1000 sensor. It is not only a representative of precision temperature measurement but also a true Straight-Tube Temperature Sensor, offering an efficient, reliable, and intelligent temperature measurement solution for confined spaces.

Straight-tube design: built for tight spaces

Traditional temperature sensors are often bulky and difficult to embed into compact equipment. The Straight-Tube Temperature Sensor features a linear straight-tube structure with an outer diameter as small as 3mm and a length that can be flexibly customized according to installation space. This design allows it to easily enter narrow areas such as pipelines, gaps, bearings, and motor windings, achieving precise temperature measurement without occupying valuable space.
In practical applications, the Straight-Tube Temperature Sensor can be installed in mounting holes as small as 6mm, greatly enhancing the flexibility of equipment integration. Whether in laboratory instruments or industrial robots, the Straight-Tube Temperature Sensor enables efficient and stable temperature monitoring without altering existing structures.

PT1000 high precision: capturing tiny changes accurately

In compact spaces, temperature changes tend to be more rapid and unpredictable. This requires sensors with high sensitivity and high resolution. That is exactly where the Miniature PT1000 Sensor excels.
As a miniature platinum resistance sensor, the Miniature PT1000 Sensor uses a PT1000 platinum resistance element with a nominal resistance of 1000Ω at 0°C. Compared with traditional PT100 sensors, it offers a higher signal change rate and is therefore more sensitive to small temperature fluctuations. The Miniature PT1000 Sensor achieves an accuracy of ±0.15°C, making it particularly suitable for confined spaces with extremely high temperature control requirements, such as medical analyzers, optical modules, and semiconductor equipment.
In addition, the Miniature PT1000 Sensor is small enough to be easily embedded into PCBs, heat sinks, or micro-reaction chambers, enabling true "plug-and-measure" functionality.

Vibration-resistant design: stable and reliable for dynamic environments

Confined spaces are often accompanied by strong mechanical vibrations — for example, in engine compartments, compressors, and wind turbines. Ordinary sensors are prone to lead breakage, loose solder joints, or signal drift under long-term vibration. The Vibration Resistant Sensor is specifically designed to solve this problem.
The Vibration Resistant Sensor features a fully sealed stainless steel housing and an internal shock-absorbing potting process, capable of withstanding vibration acceleration up to 20g (10–2000Hz). At the same time, the Vibration Resistant Sensor uses flexible, vibration-resistant lead wires that are tensile-treated to ensure long-term electrical connection reliability in continuously vibrating environments.
In fields such as rail transportation, aerospace, and heavy machinery, the Vibration Resistant Sensor has become a standard configuration, effectively reducing the risk of sensor failure caused by vibration.

Three in one: compact, precise, and durable

When the compact form factor of the Straight-Tube Temperature Sensor, the high-precision temperature measurement of the Miniature PT1000 Sensor, and the vibration resistance of the Vibration Resistant Sensor are combined, the core advantages of this compact straight-tube PT1000 sensor are fully realized.
Whether in micro-reactors, drone motors, or narrow hydraulic pipelines, this sensor can:
  • Achieve interference-free installation through the Straight-Tube Temperature Sensor design
  • Deliver high-resolution temperature feedback through Miniature PT1000 Sensor technology
  • Ensure long-term stable operation through Vibration Resistant Sensor characteristics

Typical application scenarios

  • Electric vehicle battery packs: Installed in narrow gaps between cells for real-time battery temperature monitoring
  • Precision laser equipment: Compact temperature measurement near optical paths to avoid thermal drift
  • High-speed spindle motors: Deploying the Vibration Resistant Sensor near bearings to monitor temperature rise
  • Medical PCR equipment: Using the Miniature PT1000 Sensor to precisely control reaction chamber temperature
