Differential-thermometer
The differential thermometer utilizes two probes to display the temperature difference between them instead of indicating the precise temperature. It employs a conventional meter as an indicator and has a total range of -10°C to 20°C.
The differential thermometer operates on the principle of measuring temperature differences, making it particularly useful in applications where relative temperature variations are more significant than absolute values. This device consists of two temperature-sensitive probes, each capable of detecting thermal variations in their respective environments. The output from these probes is processed to calculate the difference in temperature, which is then indicated on a conventional analog or digital meter.
The range of -10°C to 20°C suggests that this thermometer is suited for measuring relatively low temperature differences, making it ideal for laboratory settings or HVAC applications where monitoring small temperature gradients is critical. The design may include thermistors or thermocouples as the sensing elements, which convert temperature changes into electrical signals.
In terms of circuitry, the differential thermometer may incorporate an operational amplifier configuration to amplify the voltage difference generated by the probes. This amplified signal is then fed into a meter, which provides a readable output that corresponds to the temperature difference. Calibration of the device is essential to ensure accuracy across the specified range, and it may involve adjusting the gain of the operational amplifier or fine-tuning the meter's scale.
Overall, the differential thermometer is a valuable tool for applications requiring precise measurement of temperature differences, with straightforward construction and operation that leverages conventional metering technology.The differential thermometer uses two probes and shows the temperature difference betw-een them, rather than the exact temperature. The thermometer uses a conventional meter as an indicator, and it covers a total range of 20° -10°low to l0°high.
