Product Description


1/16 DIN Microprocessor Based PID Temperature Regulator

With 4 digit resolution and fully programmable decimal point, the BTC-9090, a new generation miniature controller, can be configured for linear voltage and current inputs and with the addition of a single module, with 4-20mA control output. Software has been refined over several years and offers a very logical menu structure and high noise immunity. This is one of the most versatile units available.

The Fuzzy Logic plus PID microprocessor-based temperature controller, incorporate one bright, easy to read 4-digit LED display, 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.

Plastic/rubber industry

It is installed on the heating material tube of the injection molding machine to control the temperature of the raw material, effectively control the liquid temperature of the plastic and improve the molding quality of the product.
Installed on the hot runner system for temperature control of runners and gates to stabilize the quality of the plastic.
Temperature control on the mold temperature machine, indirectly adjusting the temperature of the mold by adjusting the temperature of the hot fluid, can improve the production efficiency of the product and reduce the generation of defective products.

Electric heating furnace industry

Vacuum furnace equipment / vacuum melting / vacuum heat treatment

A new algorithm for PID adjustment using fuzzy rules is used to adjust the PID algorithm to eliminate the PID saturation integral phenomenon when the error is large. When the error is small, the improved PID algorithm is used for adjustment and can be automatically adjusted. Learn and memorize some of the characteristics of the controlled object to optimize the effect

Semiconductor industry

The temperature control of the electric heating cloth package is often used for the heating of the exhaust pipe valve parts of the semiconductor factory, the panel factory, or the special steel cylinder.

In the semiconductor temperature process control program, the heating system of the chamber, such as the decane process, the dichloromethane process

Ceramic / kiln / glass industry

Ceramic sintering furnace:
