KOBOLD TWC OEM Temperature Sensors

KOBOLD TWC temperature sensors are engineered and designed for OEM applications. There are a wide variety of options to tailor the sensor to most any application or industry. The TWC offers high precision and fast read-out times. Models are available in metal or are encased in a plastic housing which offers chemical compatibility for a wide range of aggressive media.

The TWC-N is a NTC (negative temperature coefficient) sensor, also known as a thermistor, that is able to convert small temperature changes into significant resistance changes.

The TWC-P utilizes a PT (platinum resistance) sensor that is ideal for simple, precise, and linear measurements.

Sample TWC Application Areas

TWC sensors have been used in cars with electrical engines. If heat builds up in the motor because of mechanical failures or coolant blockages, it could lead to damage or destruction of expensive components. TWC temperature sensors prevent this as they can be triggered if defined conditions are exceeded, both while driving and when charging.

They have also been used for monitoring the electrical components found within switch cabinets, generators, and distribution systems for wind turbines.

TWC temperature sensors have also been used in the medical industry to monitor the temperature of liquid infusions as they are administered to the patient.They can also maintain the temperature of blood banks to maximize “shelf life”.

Other sample TWC application areas include:

  • Green Energy Generation
  • Building Services and Automation
  • Industrial Process Monitoring and Control
  • Power Transmission and Conversion
  • Automotive Industry
  • Charging Stations
  • Laboratories
  • Greenhouses

The TWC is a fit for most anywhere temperature needs to be monitored/measured in a highly efficient and accurate manner for a low cost.

What is a NTC Thermistor?

A NTC (Negative Temperature Coefficient) temperature sensor is a type of thermistor, which is a resistor whose electrical resistance changes with temperature. NTC thermistors are characterized by having a resistance that decreases as the temperature increases. In other words, the resistance of an NTC thermistor is negatively correlated with temperature.

The resistance-temperature relationship of an NTC thermistor is highly nonlinear, and it can be described by a specific mathematical equation or curve. Typically, as the temperature rises, the resistance of the NTC thermistor drops rapidly, and as the temperature decreases, the resistance increases.

NTC temperature sensors are commonly used for temperature measurement and control in various applications due to their small size, high sensitivity, and relatively low cost. Some key features and applications of NTC thermistors in general include:

  • High Sensitivity - They provide precise precision and a sensitivity for subtle shifts in temperature.
  • Temperature Compensation - They are often used for temperature compensation in electronic circuits and sensors to maintain accuracy.
  • Temperature Control - They are used in appliances like ovens, air conditioners, and refrigerators to monitor and control temperature.
  • Inrush Current Limiting - They can be employed to limit inrush current when powering up electronic devices.
  • Medical Devices - They can be used in medical devices for temperature measurement and monitoring.
  • Automotive - They are used in automotive applications, such as engine temperature measurement and HVAC systems.
  • Industrial Control - They are utilized in industrial settings for temperature monitoring and control in various processes.
  • Consumer Electronics - They are used in various consumer electronics, such as battery charging circuits and temperature-compensated crystal oscillators.

What is a PT Temperature Sensor?

A PT temperature sensor, also known as a platinum temperature sensor, refers to a type of temperature sensor that uses platinum as its temperature-sensing element. PT sensors are known for their high accuracy and stability over a wide temperature range. There are two common types of PT sensors: the PT100 and the PT1000, based on the resistance-temperature relationship of platinum.

PT100 Temperature Sensor: The PT100 sensor, often referred to as a platinum resistance thermometer (PRT), has a resistance of 100 ohms at 32°F. Its resistance increases linearly with temperature. This type of PT sensor is used in various applications where precise temperature measurement is required, such as laboratories, industrial processes, and scientific research.

PT1000 Temperature Sensor: The PT1000 is similar to the PT100, but it has a resistance of 1000 ohms at 32°F. The PT1000 is often used in applications where higher resolution and accuracy are required. The increased resistance provides better sensitivity to temperature changes, making it suitable for more demanding applications.

Platinum temperature sensors offer several advantages:

  • High Accuracy - They are known for their high accuracy and repeatability, making them suitable for critical temperature measurement applications.
  • Wide Temperature Range - They can operate over a wide temperature range, from cryogenic temperatures to high-temperature environments.
  • Stability - PT sensors exhibit excellent long-term stability, which is essential in applications where accuracy must be maintained over time.
  • Linearity - The resistance-temperature relationship of platinum is nearly linear, simplifying calibration and interpolation.
  • Low Drift - PT sensors experience minimal drift, ensuring reliable and consistent temperature measurements.

PT temperature sensors are used in a wide variety of industries: scientific research, industrial processes, HVAC systems, medical devices, and environmental monitoring. To use PT temperature sensors effectively, they are often connected to appropriate instrumentation, such as bridge circuits, to convert the resistance changes into accurate temperature readings. Calibrations and corrections are also commonly applied to ensure accurate temperature measurement.
