PID Temperature Controller with Programmable Input
The BTC-2500 Temperature Thermostat is available with 3 outputs, 2 from the list above as well as an alarm output.
All BrainChild Fuzzy Logic plus PID microprocessor-based thermo controller, 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.
All BTC models have programmable rate of temperature rise and an inbuilt timer that will bring a process up to temperature at a set rate and hold it for a predetermined time before switching off. BrainChild is professional and experienced in the field of high-performance and quality temperature controllers. No matter what kinds of industrial electronic temperature controls you need, we are confident to satisfy your specific requirements.
