P41 / Ramp Soak ControllersThe Fuzzy Logic plus PID microprocessor-based profiling controller with many segments of ramp and dwell, incorporate two bright, easy to read 4-digit LED displays, indicating process value and set point value. The Fuzzy Logic technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance.

As a professional and experienced manufacturer, we supply high-performance and quality ramp soak controllers, which is also called programmable temperature controllers.


  • Total 9 profiles, a profile with 16, 32 or 64 segments at most
  • Each segment to be configured as a ramp or dwell(soak)
  • Fast A-D sampling rate (5 times/s)
  • After an event the process goes to run, hold, abort, manual, failure transfer, off mode, next segment or select the second PID values
  • High accuracy of 18-bit A to D input, and 15-bit D to A output
  • The fast sample rate of 200 msec
  • Fuzzy control to reach set point at the least overshooting ans less time
  • Up to three relays are configurable for event output
  • Analog retransmission of process value & set point value
  • Optional RS-485 or 232 communications
  • Programmable port for easy configuration or calibration
  • Lockout protection for security requirement
  • Bumpless transfer of safely control while sensor breaks
  • Digital filter to improve the stability of process value
  • SEL function for easy operation
