HVAC System activated through an SCADA

HVAC System activated through an SCADA

Introduction As a continuation of the Air-conditioning system post, in today´s newsletter Opiron suggests to expand the HVAC system controlled through the Touchberry Pi Panel PC and Ardbox Relay from IndustrialShields. As the last post, the suggested SCADA that will run on the Touchberry Pi is the following: myscadatechnologies.com Summarizing the previous post, we designed a system that was able to activate the air conditioning with a relay. In order to expand the system, we will include the following sensors to have a complete automatic…

Controlling temperature with a got exchanger through a modulating valve in chemical industry

Controlling temperature with a got exchanger through a modulating valve in chemical industry

Introduction In industrial applications, the need to control temperature is usual. A typical element used and designed with this purpose is the hot exchanger, which interchanges two or more fluids with different temperatures.In this post we are going to explain how to implement a temperature control through a modulating valve that will regulate the amount of steam that enters the hot exchanger, in order to heat the chemical process. To fulfill the specified requirements, Opiron electronics has developed a PID algorithm…

Feeding a packaging machine with a frequency driver with Arduino

Feeding a packaging machine with a frequency driver with Arduino

In the dairy industry, packaging machines are used to package food in containers such as yogurt, milk, etc. They are usually integrated into more complex systems, and they are fed by a tank that contains the product (usually milk). In this project we will design a system composed of a tank with milk, a packaging machine, a valve to open and close the way to the machine, and a PID formed by a flow meter and a pump controlled by…

How to generate a different PWM’s signals with ours equipment’s

How to generate a different PWM’s signals with ours equipment’s

On this example is explained how to generate a PWM with M-DUINO and ARDBOX. In our equipment’s you can generate a PWM on Digital/Analog Ports. But most of these ports have a limitation of frequency (500 Hz approx.). PIN3 for ARDBOX and PIN3 and PIN2 for M-DUINO don’t have limitation and they can generate a PWM between 100Hz (even less) and 8MHz. PIN3 for ARDBOX can work as an external output for the Timer/Counter0 Output Compare B (OC0B). And the…
