TESK301 Cryogenic Temperature Controller

TESK301 Cryogenic Temperature Controller

TESK301 low-temperature temperature controller is a high-precision single-loop low-temperature temperature control system independently developed by Beijing Jinzhengmao Technology Co., Ltd., which can realize the temperature control output from 20K-600K. The temperature control system has one sensor input and one heating output function, and the sensor input and heating output form a control loop. TESK301 single-channel design can meet most laboratory research and industrial low temperature temperature control use. With appropriate sensors, the low temperature can be measured as low as 20K, the high temperature can reach more than 600K, and the resolution can be as high as 10mK. The heating output power is divided into three adjustable levels, the low level is as low as 0.8W, and can reach 80W, which can meet the heating needs of most low-temperature equipment.

The front panel of the TESK301 cryogenic temperature controller has a bright yellow digital tube and a red indicator light to ensure that the temperature readings at all angles are clearly visible. The key position setting is standardized, and the key icon is clear and clear. At the same time, TESK301 has three output power ranges, which fully guarantees the stability of temperature control in each temperature control interval and reduces temperature overshoot. The standard RS232 interface is installed, which can be controlled by the host computer through the control software, and users can also develop their own application software.

TESK301 has a built-in standard constant current power supply to supply power to the resistance thermometer. The voltage signal of the temperature sensor is measured by the four-wire method. After 16-bit A/D conversion, self-calibration, digital filtering, checking the graduation table, the measured temperature is displayed after correction and calculation. After the set temperature is compared, the real-time PID operation gives a control signal, and the heating voltage is periodically controlled by the solid-state relay in the machine to realize the temperature control.
