Various functions to achieve high precision

Newly Developed - Temperature/Humidity Sensor

Newly Developed - Temperature/Humidity Sensor

Improved temperature resolution

Loaded with a newly developed highly directional small-size temperature sensor. Its 14bit A/D converter improves its temperature resolution. The digital transmission of temperature data can be done with stability via a LAN cable since it is strong against external noise.

Achieving real time arithmetic processing

With multitask processing enabled by the internal DSP total 32-bit CPU and high speed CPU, complicated and voluminous arithmetic processing can be performed in real time in a short period of time. Starting with newly developed high speed autotuning, high precision and high stability processing at amazing speeds is made possible with various new technologies such as intelligent sensing control, etc.

Newly Developed - ISC

Achieving high stability, precise control

Fundamental general-use temperature control program PID control has been newly developed as our own specialized precision air conditioning program "ISC (intelligent sensing control). Control algorithms were developed utilizing expansive accumulated data. Traditional PID control overshoot patterns have been dramatically improved. Achieving previously unheard of stability and control.

Newly Developed - High speed autotuning

Newly Developed - High speed autotuning

Arithmetic processing at over 10x traditional speeds

The dual processor with 32bit internal DSP CPU and high speed CPU can process several hundred steps of calculations at once. It has also achieved a dramatic shortening of autotuning time. Also, even when external turbulence causes instability in sample data, the appropriate PID value is immediately decided from the observed waveforms.

Newly Developed - 2-phase humidification control

Dual CPU loaded

Prevents excessive overshooting

Water temperature inside the humidifier is observed, and PID control is implemented once the temperature rises above a set temperature. Different from general methods with which PID control starts regardless of internal tank water temperature, excessive overshooting is prevented, and stable humidification control is made possible.
