Welcome to STL Controls Website

STL Controls has designed and built many controlled systems for factories, petrol-chemical, marine industries. Examples of the systems that we had built are as follows; 1. Valve Control System (Marine) 2. Star-Delta Motor Starting System (Manufacturing) 3. pH and Conductivity Monitoring System (Chemical Plant) 4. Lube Oil Heating System (Petrol Chemical Plant) 5. Water & Fuel Oil Tank Gauging System (Marine) 6. Automatic Water Pump Control System (Factory) 7. Air Bubbling System (Factory)
pH & Conductivity Monitoring System
We also provide customized electronics micro-controller packages to handle the raw signal coming from industrial sensors such as pressure transmitter, thermocouple, flowmeter, speed sensor, air pressure sensor, hall switches, etc.. Types of Micro-Controller: 1. Arduino Nano 2. ESP-01 (WIFI) 3. ESP-8266 (WIFI) 4. ESP-32 (WIFI) Training on Programming of Arduino Micro-controller includes: 1. Digital Input / Digital Output 2. Analog Input (4 - 20mA sensor) 3. Analog Output (PWM - speed control of DC motor) 4. Switching ON AC/DC load with 5Vdc Digital Output (Relay or SSR) 5. Display data on I2C LCD and OLED 6. Using DTS1307 or DS3231 Real Time Clock (RTC) 7. Using Ultra-sonic Ranger Finder Module 8. Using HC-06 bluetooth unit with Android APPS 9. Using the Interrupt Service Routine (ISR) function 10. Obtaining raw data from environmental sensor with SDI-12 output
