The application and working principle of 194400-01 are important for understanding the workings of this device. This unit is a type of precision temperature measurement instrument capable of measuring temperatures from -20°C to 40°C with a resolution of 0.5°C. As stated in the operating manual, the accuracy of the readings is ±1°C. This instrument is used to measure temperatures in a range of industrial and laboratory settings, such as research and development, medical and clinical laboratories, quality control, and environmental monitoring applications.

The 194400-01 is powered by a constant voltage power supply. It is supplied with a probe and is used to measure temperatures from 0 to 40°C with a resolution of 0.1°C. The accuracy of the unit is ±0.2°C. The temperature probe is a temperature-sensitive device that can detect temperature changes due to its resistance-temperature relationship. This device has a galvanic current circuit, which is comprised of a positive and a negative terminal. The temperature probe is connected to the positive and negative terminals respectively. When a voltage is applied to the terminals, the resistance of the temperature probe changes with temperature.

The 194400-01 measures temperature through a two-wire system. The two wires are insulated in a probe. One terminal of the probe is connected to the instrument’s negative terminal, while the other terminal is connected to the instrument’s positive terminal. An electric current flows through the probe, and its resistance is measured. When the temperature of the measured object changes, the resistance of the probe changes as well. The varying resistance is then translated into a voltage level, which in turn is translated into a temperature reading.

The 194400-01 is based on the Wheatstone Bridge principle. This is a type of direct current electrical circuit that allows for measurements to be taken in a highly precise way. The Wheatstone Bridge is made up of four resistors with two input terminals and two output terminals. The 194400-01 has two resistors working in a bridge custom connection. When a voltage is applied to one or both of the terminals, the resistance in the bridge connection changes, which is then translated into a temperature value.

The 194400-01 is designed for long-term, stable temperature measurements. It is equipped with advanced temperature compensation circuits, which allow it to remain stable when temperatures fluctuate significantly. Additionally, it is equipped with a button to zero, which allows for zero calibration whenever desired. This allows for precise calibration, ensuring a repeatable, reliable temperature measurement.

In conclusion, the 194400-01 is a precision temperature measurement instrument designed for industrial and laboratory applications. It is based on the Wheatstone Bridge principle and has a probe to measure temperatures with a resolution of 0.1°C and accuracy of ±0.2°C. It is equipped with a zero calibration button for accurate calibration and temperature compensation circuits for stable readings. It is an all-in-one instrument suitable for a variety of temperature measurements.
