The maximum temperature measurement range of the HY8000 intelligent temperature monitor varies according to its specific model and the type of sensor selected. In general, the series supports multiple types of temperature sensor inputs, including but not limited to thermocouples and thermal resistors, which have their own measurement ranges and characteristics.

HYT8000 series intelligent temperature controller (Note that there may be a typo in the original "HY8000 intelligent temperature monitor", because no direct information about "HY8000" can be found, and "HYT8000" is a clear intelligent temperature controller model. Therefore, the following is answered in accordance with the "HYT8000 series intelligent temperature controller") is a high-performance, high-reliability intelligent industrial regulation instrument, the following is a detailed overview of it:

Main functions and applications

HYT8000 series intelligent temperature controller can receive thermocouple, thermal resistance, analog and other signal input, the range can be set freely. It is mainly used in machinery, chemical industry, ceramics, light industry, metallurgy, petrochemical, heat treatment and other industries to achieve automatic temperature control. By combining fuzzy theory with traditional PID method, the temperature controller can realize fast and steady control.

Input specifications: The temperature controller is compatible with a variety of input signals, including thermocouples (K, J, E, S, N, T, B, R, Wre, etc.), thermal resistance (CU50, PT100), and linear signals (0-5V, 1-5V, 0-10mA, 4-20mA, etc.).

Measurement range and accuracy: a wide range of measurement, such as K-type thermocouple measurement range of -50℃ to +1350℃, PT100 thermal resistance measurement range of -200.0℃ to +600.0℃. Measuring accuracy up to 0.2 (±0.2%F±1 word).

Adjustment mode: Intelligent PID adjustment is adopted. P, PI, and PID adjustment can be composed according to different P, I, and D parameters. Master output Optional relay contact switch, trigger solid state relay logic level, phase shift trigger pulse, zero crossing trigger pulse and 4-20mA analog output.

Alarm function: with upper limit, lower limit, upper deviation, lower deviation and other alarm functions, can be output through the relay contact.

Power supply and environment: Power supply is 220VAC, -15%, +10%/50-60HZ, power consumption ≤5W. The ambient temperature must range from 0 to 50 ° C.

In addition, the HYT8000 series intelligent temperature controller also has the characteristics of software zero adjustment, cold end temperature measurement, amplifier self-stabilizing zero, etc., the display accuracy can be better than 0.2%FS. Thermal resistance can be measured separately, completely removing the influence of line resistance.

After the temperature controller is powered on, the PV window displays the input type and the SV window displays the maximum range. The PV window then displays the measured value and the SV window displays the set value. This is the standard display of the meter. In standard display mode, the meter may flash alternately to display the PV value and the following characters:

HHHH: indicates that the input signal is exceeding the range, which may be caused by incorrect sensor specifications or open input circuit.

LLLL: indicates that the input signal has a negative overrange, which may be caused by sensor errors, reverse connections, or short circuits.

ERRO: indicates that the analog to digital converter overflow of the instrument may be caused by sensor specification error, reverse connection, short circuit or open circuit.

When HHHH and LLLL are displayed, the flashing PV value is generally still correct; However, when displaying ERRO, the displayed PV value is generally incorrect.

HYT8000 series intelligent temperature controller also has a variety of additional functions, such as temperature tracking, overtemperature output prohibition. Users can adjust the working state of the instrument through parameter setting to meet different control requirements. The parameter setting can be operated by the button of the instrument, which is convenient and fast.

In summary, the HYT8000 series intelligent temperature controller is a powerful and stable industrial regulation instrument. Its wide range of applications and flexible configuration options make it an important component in the field of industrial automation.
