AI 5500 Precision Thermometer

A. Product Overview

The Yudian AI 5500 Handheld Digital Thermometer is designed for users who need reliable and precise portable temperature measurement. The instrument combines high stability, low power consumption, multiple sensor input options and straightforward keypad operation in a compact handheld format.

It supports the following temperature sensor inputs:

Pt100 RTD

K type thermocouple

S type thermocouple

E type thermocouple

T type thermocouple

J type thermocouple

R type thermocouple

B type thermocouple

N type thermocouple

For thermocouple measurements, the AI 5500 provides internal, external and manual reference junction compensation modes.

The thermometer also provides mathematical measurement functions including relative value, maximum temperature, minimum temperature, average temperature, peak to peak value, standard deviation and sampling count.

The display resolution can be selected between 0.1 degree Celsius and 1 degree Celsius, while temperature readings can be displayed in Celsius, Fahrenheit or Kelvin according to application requirements.

Additional functions include upper and lower temperature alarms, user calibration, sensor offset correction, display hold, automatic backlight shutdown, automatic power shutdown and low battery detection.

B. Working Principle

The AI 5500 works by receiving the electrical signal generated by a connected temperature sensor and converting that signal into a temperature reading.

When a Pt100 RTD sensor is used, the instrument measures the change in electrical resistance of the platinum sensing element as temperature changes. The AI 5500 uses a four wire connection for Pt100 measurement, which is particularly useful for reducing measurement errors caused by lead wire resistance.

When a thermocouple is connected, the instrument measures the thermoelectric voltage generated by the thermocouple. The user selects the appropriate thermocouple type, such as K, J, T, E, S, R, B or N, and the thermometer converts the measured signal into the corresponding temperature value.

For thermocouple applications, the AI 5500 supports internal reference junction compensation, external compensation and manual compensation.

The measured temperature is shown on a six digit LCD display. The instrument can simultaneously calculate values such as maximum, minimum, average, relative temperature, peak to peak value and standard deviation.

C. Why the Yudian AI 5500 is Used

The AI 5500 is used when accurate and repeatable portable temperature measurement is required across a wide range of temperatures and sensor types.

One major advantage is its ability to work with both Pt100 RTD sensors and several thermocouple types. This allows one instrument to be used for many different temperature measurement applications instead of requiring separate meters.

Depending on the selected sensor, the AI 5500 provides wide measurement ranges. For example, Pt100 measurement extends from minus 200 to 850 degrees Celsius, while a K type thermocouple can measure from minus 200 to 1372 degrees Celsius. Other supported thermocouples provide measurement ranges suitable for even higher temperatures.

The statistical functions are useful when users need to observe temperature variation over time. Maximum, minimum, average and peak to peak readings can help engineers identify process fluctuations that may not be obvious from a single temperature reading.

Upper and lower temperature alarm settings are also available. The instrument can indicate when the measured temperature goes below the configured lower limit or above the configured upper limit.

User calibration and sensor offset correction make the thermometer suitable for applications where measurement accuracy needs to be checked or adjusted periodically.
