HEL-777-A-T-0

Introduction

The HEL-777-A-T-0 temperature detector is a type of resistance temperature detector (RTD) that measures the temperature levels by measuring the temperature-dependent electrical resistance of metal elements. The RTD has the capacity to measure levels of temperatures up to 600°C, proving this detector to be highly advantageous over other thermocouples under extreme settings. The RTD detector is also highly reliable, as the resistance sensor creates more stable readings under changing temperatures compared to other thermometers. Similar to other thermometers, RTD detectors can be paired with data loggers, industrial controllers and signal conditioners to form complete temperature systems.

Application Field

The HEL-777-A-T-0 has a wide range of applications, from medical to industrial to laboratory. The RTD technology can be found in medical settings, such as in thermometers or kidney dialysis machines, and industrial settings, such as in flow meters or air conditioning systems. In laboratory settings, the RTD is commonly used in scientific research, data monitoring, and processes with complex temperature control requirements. The HEL-777-A-T-0 has also been used in the production of industrial chemicals, the food and beverage industry, and in various academic and research laboratories.

Working Principle

An RTD typically consists of a coiled sensing element made of material with a predictable temperature-dependent electrical resistance. The wires leading from the sensing element to the reader are usually insulated on the inside and covered in a protective outer casing to protect the connection from environmental influences. The specific type of RTD used in the HEL-777-A-T-0 is made of copper-constantan alloy, providing a temperature range of -200°C to 600°C. The RTD’s electrical resistance increases with a rising temperature. By measuring this change in electrical resistance, the temperature can be accurately determined. In general, the greater the change in electrical resistance the greater the accuracy of the temperature measurement.

Conclusion

The HEL-777-A-T-0 temperature detector is a resistance temperature detector (RTD) used in a wide range of applications from medical to industrial to laboratory. It is capable of measuring temperatures up to 600°C, making it very reliable and advantageous over other thermometers. The working principle of RTD is based on the fact that the electrical resistance of metal elements increases with increasing temperature. The RTD thus measures the change in electrical resistance to detect temperature levels with great accuracy.
