In the process of industrial automation and precision instrument monitoring, the accuracy and stability of temperature measurement have always been key factors.
Hirschmann Temperature Sensor, with its excellent technology and reliable performance, has become the preferred device for temperature monitoring in many fields, providing protection for industrial production and scientific research.
1、 Core technical principles
Hirschmann Temperature Sensor is mainly based on the principle of resistance or thermocouple to achieve temperature measurement.
Resistance sensors convert resistance signals into electrical signals based on Ohm’s law by sensing the changes in resistance values of temperature sensing elements (such as platinum resistors) at different temperatures;
Thermocouple sensors, on the other hand, utilize two different conductors to form a closed loop, generating the Seebeck effect of thermoelectric potential under temperature gradient, and converting temperature changes into measurable voltage signals.
Both principles have been meticulously designed and calibrated to ensure the accuracy and stability of temperature signal conversion.
2、 Excellent performance advantage
（1） Ultra high measurement accuracy
Whether it is a resistive or thermocouple sensor, Hirschmann uses high-quality temperature sensing materials and advanced manufacturing processes. Its temperature measurement error can be controlled within a very small range, and even in complex environments, it can accurately capture temperature changes, providing reliable data support for equipment operation and process control.
（2） Strong signal transmission capability
The Hirschmann interface is a major feature of Hirschmann Temperature Sensor. This interface has excellent resistance to electromagnetic interference, ensuring that signals are transmitted over long distances without attenuation or distortion even in strong electromagnetic environments, and ensuring real-time and accurate feedback of data to the control system.
（3） Wide temperature range and high protection characteristics
Hirschmann temperature sensors can operate stably from extremely cold -40 ℃ low temperature environments to high temperature conditions of 150 ℃. At the same time, its high protection level design enables it to resist the erosion of water, dust, and corrosive substances, and can handle both harsh outdoor natural environments and complex working conditions in chemical production with ease.
（4） Convenient installation and maintenance
The sensor adopts a modular design, supporting multiple installation methods and adapting to different devices and systems. Moreover, its structural design is reasonable, and daily maintenance operations are simple, reducing the maintenance costs and downtime of enterprise equipment.

In the automotive engine management system, Hirschmann Temperature Sensor monitors the temperature of key parts such as engine coolant, oil, and intake in real time, helping ECU (Electronic Control Unit) accurately adjust fuel injection and ignition timing, improve engine efficiency and stability, and reduce emissions and pollution.
（2） Industrial automation
Temperature is an important parameter that affects product quality and equipment lifespan in various production lines and mechanical equipment. Hirschmann temperature sensors are widely used for temperature monitoring of equipment such as motors, bearings, and heating furnaces.
By integrating with PLC (Programmable Logic Controller) or DCS (Distributed Control System), they achieve automated temperature control and fault warning, ensuring safe and efficient operation of the production process.
（3） Energy and Electricity
In power facilities such as substations and power plants, Hirschmann Temperature Sensors are used to monitor the temperature of key parts such as transformers, switchgear, and cable joints. Timely identify potential overheating hazards of equipment, prevent power accidents caused by abnormal temperature, and ensure stable and reliable power supply of the power system.
（4） Research and Medical
Accurate temperature control is crucial in laboratory research and medical equipment. Hirschmann temperature sensors, with their high precision and stability, meet the measurement needs of temperature sensitive scenarios such as biological incubators, drug storage equipment, and chemical reaction vessels, providing accurate temperature data for scientific research experiments and medical applications.
