Temperature Logging with the USB RTD Pt100 / Pt1000 Input Module

USB RTD Input Module

In the case a control and data acquisition solution is needed for any job, LucidControl USB RTD Input Modules are suitable because of handling digital and analog channels as well.

The LucidControl automation solution is inexpensive and additionally prepared for portable products as a result of being USB power supplied and there are no additional power adapters necessary.

In order to run the USB IO Module the primarily stuff that is needed is a connection to an ordinary Universal serial bus port.

LucidControl RTD Pt100 / Pt1000 USB Input Modules can be integrated without much hassle to switch boxes which are quite typical in automation field because of the variable DIN-rail mountable housing. Additionally, the IO modules are supplied with most reliable and plugable connections which is helpful for most applications in general.

For automation field the reliable USB IO Modules can be integrated to distribution boxes making it simple realizing a tidy and straight forward development e.g. for controlling lights.

Because of an comprehensive documentation, professional software tools and APIs for most relevant development environments and also their straight forward use make the USB IO Modules a great automation solution for newbies as well as for experts. In the training division, the equipment can be employed by students to do their first steps in automation development.

Without needing extra drivers, the USB IO Modules are working out of the box with many relevant computers and work with MS Windows® or Linux operating systems. Beside of ordinary computers they are also compatible with embedded computers such as the Raspberry Pi what makes the IO equipment extremely useful.

Making use of Linux operating system these micro-sized computers are absolutely best suited to build web based programms making all input output functionality available through the net.

Explaining Temperature Measurements with the USB RTD Input Module

The conditions of up to 8 Pt100 or Pt1000 RTD temp sensor elements can be acquired by the USB RTD Input Module.

The input lines have been created in order to sense the electrical resistance of a Pt100 / Pt1000 Resistance Temperature Detector and determine the related detectors temp as a eventual result.

The RTD sensor elements are captured with highest accuracy by applying a constant current to the RTD while measuring its electrical resistance that is relative to the temperature of the surrounding.

After measuring the resistance, the temperature measuring devices calculate the represented temperature and forward it for the connected host computer.

A perfect trade-off related to cost and precision was found because the USB RTD input modules support a wide temperature range of ±180°C or 0-360°C while granting an typical accuracy of ±0.5°C.

In conjunction with the other devices of the LucidControl series heat control and energy management are only two potential applications to mention here. Applications controlling for example heating elements can be build with pulse-width-modulated digital outputs of the USB Digital Output Module where the relevant temperatures are acquired by the USB RTD Input Module.

In order to make this product as valuable as feasible and to manage the majority of possible projects, it is our goal to cover a number of analog and digital signals with this USB Devices. Extra insights about the LucidControl USB input output modules are available on our site.


Acquisition of 4/8 temperature sensors Pt100/Pt1000

The LucidControl RTD Input USB Temperature Measurement Module captures the resistances of up to 8 standard Pt100 / Pt1000 temperature sensors and calculates the resulting temperature.

The USB RTD Input Module acquires the resistance of the RTD by sourcing a constant current. 2-wire connection is used for each sensor.

Wide range and high precision temperature measurement interface

It combines high accuracy of 0.5 °C with a wide temperature range of ±180°C or 0-360°C.

Typical application

The LucidControl RI4/RI8 is ideally suited for industrial and home automation applications where temperatures are measured, processed or monitored.
In combination with other devices of the LucidControl USB IO module series, the RI4/RI8 is able to control energy management systems as they are used in central heatings.

Together with the DO4 module it can control the power of a heating plate in order to ensure constant temperature.
