On this page you will find general information about temperature measurement, control, monitoring and registration.
PID control algorithm explanation
The correct adjustment of a PID (temperature) controller can sometimes be difficult. To guide you we made an information page on this subject:
- explanation of the P (proportional band), I (integration) and D (differentiation) parameters
- how to adjust these P, I and D parameters correctly
Explanation of thermocouples and Pt100 temperature sensors
2 types of sensors are mostly used for temperature measurement: thermocouples and Pt100 RTD sensors. This page gives more detailed information on:
- history of temperature measurement
- the first really good useable thermometer, made by Daniel Gabriel Fahrenheit around 1714 in Amsterdam incl. the development of his Fahrenheit temperature scale.
- Thermocouple:
- operating principle
- correct connection (thermocouple cable, compensationcable, thermocouple connectors, polarity)
- common mistakes with thermocouples
- Pt100 resistance thermometer (RTD) and SPRT (standard platinum resistance thermometers for calibration purposes):
- measurement principles
- correct connection (2-, 3- or 4-wire)
- differences between thermocouples and Pt100/SPRT sensors
- accuracy classes of thermocouples and Pt100/SPRT sensors
Electronic power switch: the thyristor
Electronic power “switches”, also known as thyristors, are being used in process controls for the switching of high electrical power levels through electrical heating elements.
There are versions available for:
- currents from 10-2100 Ampere
- voltage up to and including 690Vac
- 1, 2 of 3 phase net power
In order to make things more clear regarding thyristors and how they operate, we created a page with information with the following subjects:
- what is a thyristor?
- how does a thyristor work?
- what are the advantages and disadvantages of a thyristor?
- what kind of control methods are being used for a thyristor?
- how do I couple a process control with a thyristor?
