Typical applications:

Currently focused on the fields of pharmaceuticals, healthcare, food, and metrology.

In the pharmaceutical industry, with the implementation of the new pharmacopoeia, most pharmaceutical factories use it for temperature validation of high-temperature pressure sterilizers, sterilization validation of pharmaceutical packaging materials, and temperature and humidity validation in drug stability tests. In the food industry. Mainly export-oriented enterprises, used to record temperature and pressure data during the sterilization process of packaging cans or bags, in order to control and improve the process and optimize processing parameters. In the manufacturing industry of spray can products (pesticides, hairspray, mousse, shaving foam, etc.), manufacturers use TMI products to detect the internal pressure changes of spray cans at different temperatures after filling, so as to improve the safety of product use and transportation.

Sensor malfunction:

Open circuit or short circuit:

Performance: Abnormal display values (such as fixed maximum or minimum values) or significant fluctuations.

Reason: The lead of the thermistor (PT100) is broken, the thermocouple wire is oxidized, or the insulation is damaged.

Handling:

Use a multimeter to check the resistance (showing infinity when open circuit, abnormally low resistance when short circuit).

Replace the sensor or repair the insulation layer (such as blowing dry the water inlet protective sleeve).

Improper installation:

Performance: The measured value deviates from the actual temperature.

Reason: Insufficient insertion depth (should be ≥ 8-10 times the diameter of the protective tube), close to a heat source or strong magnetic field.

Solution: Adjust the installation position to ensure that the sensor fully contacts the measured medium and is away from interference sources.
