Precise Temperature Data Logging and Recording

Did you know that temperature is the most often recorded physical measurement? Knowing the temperature is critical for the correct operation of everything from the human body to an automobile engine, and everything in between. Temperature can affect the durability of your products and can frequently be the reason for mechanical and other types of defects. That is why precise temperature measurement is crucial for any R&D testing application as well as for long-term monitoring purposes in industrial and production environments.

There are several sensor types used for measuring temperature. The most common and popular sensors for temperature measurement today include thermocouples, RTDs, thermistors, and even infra-red temperature detectors.

Dewesoft temperature data loggers offer support for all of them and we even offer temperature loggers with combined sensor type compatibility.

Precise Temperature Data Logging and Recording

What is Thermocouple Sensor?

The most popular temperature sensors overall due to its relatively low cost and reliability is the thermocouple. Thermocouples are based on the Seebeck effect, which shows that when a pair of dissimilar metals in contact with each other at each end are subjected to changes in temperature, they create a small voltage potential.

Pairing different kinds of metals give us a variety of measuring ranges. These are called “types.” A very popular one is thermocouple Type K, which pairs chromel and alumel, resulting in a wide measuring range of −200 °C to +1350 °C (−330 °F to +2460 °F). Other popular types are J, T, E, R, S, B, N, and C.

The output from a thermocouple must be linearized by the measuring system. It must also be referenced using the Cold Junction Compensation (CJC). The “hot junction” is the measuring end of the thermocouple assembly, and the other end is the cold junction, where the reference is typically located.

Thermocouple Measuring Challenges and Solutions

Due to the very small microvolt and millivolt output of these sensors, electrical noise and interference can occur when the measuring system is not isolated. Dewesoft modules tackle this head-on with powerful isolation. There is no better way to reject common-mode voltages that get into the signal chain.

Another way to reduce noise is to place the measuring system as close to the sensor as possible. Avoiding long signal lines is a proven strategy for maximizing signal fidelity and reducing costs. Look at our SIRIUS and KRYPTON modular data acquisition instruments for best-in-breed solutions here.

An inadequate CJC results in wrong readings. This assembly needs to be protected from ambient temperature changes to provide a solid reference. We use a separate CJC chip for each channel in our CJCs, which are milled from a solid block of aluminum, and precisely assembled to achieve the best possible reference.

What is the RTD - Resistance Thermometer Detector?

Compared to the thermocouple, the RTD (Resistance Temperature Detector) is generally more linear and drift-free within its measuring range. However, due to their platinum content and more complex construction, they are more expensive than thermocouples. You will typically find RTDs used in applications such as pharmaceuticals, where precise temperature measurements must be made over a long time. They don’t range much above 600° C, however, so thermocouples are a better choice for high temperature “contact” applications.

Unlike the thermocouple which is self-powered, the RTD is powered by the measuring system. The RTD measures temperature via electrical resistance which changes in a highly linear fashion with respect to temperature. Although at its core an RTD is a 2-wire sensor,
the addition of one or even two more wires (3 and 4-wire hookup) provides better compensation against self-heating and lead wire resistance and is recommended. Dewesoft signal conditioners provide 2, 3, and 4 wire hook-up possibilities.

The PT100 (“PT” = platinum and “100” = 100Ω at 0°C) and PT1000 are the most popular variants of the RTD, however, we also support Pt200, Pt500, and Pt2000 sensors.

RTD Measuring Challenges and Solutions

As mentioned, their hook-up is more complex than a thermocouple, however, Dewesoft DSI-RTD adapters make it easy and convenient to connect your sensors to our measuring systems.

Noise is always a consideration for any sensor with small output, but our high isolation inputs are the best prevention imaginable.

Rugged Temperature Data Loggers for Harsh Environments

Temperature Data Recording Software Included

All our temperature data loggers come included with the award-winning DewesoftX data acquisition software. The software offers an intuitive user interface and is very easy to use.

The software offers several storing, triggering, and alarm options. Unlimited mathematical channels like formulas, statistics, filters, and many others can be defined. Several pre-built visual displays are available for data visualization - recorders, digital displays, analog displays, tables.

DewesoftX built-in tools for report generation tools enable easy creation of PDF and Word reports. Data exporting tool supports exporting data to several industry-standard data formats.

Temperature Data Recording Software Included

Triggers and Alarms

Our software allows setting up unlimited triggers, alarms, and notifications. You can enable four different storage options that relate to the basic sampling rate. Any of the four options can be used to store data:

Always fast: data will always be stored at full sampling speed, as defined by the dynamic acquisition rate.
Always slow: data will be always stored at reduced sampling speed as defined by the static/reduced rate.
Fast on the trigger: data will be stored at full sampling speed defined by the dynamic acquisition rate once the trigger condition occurs.
Fast on trigger slow otherwise: data will be stored at full sampling speed defined by the dynamic acquisition rate at trigger points, and with the reduced rate when there is no trigger.

Data is only stored when one or more trigger conditions are met. The software also allows us to set "pre" and "post" trigger time to store data before and after the trigger condition is met.

No data is stored between trigger conditions. The amount of stored data is kept to a minimum. We can easily move between trigger windows and analyze the events. The recorder screen offers cursors for absolute values, time, or frequency.

Long-term Temperature Monitoring

For long-term or permanent temperature monitoring, we offer temperature data loggers with the ability to store data into the local or cloud database based on OPC UA standard protocol.

The Historian software package provides a time-series database for long-term or permanent data recording. The database can be either located locally, on the remote server, or in the cloud. The solution is based on the InfluxDB time-series database open source project.

Historian provides several useful features for your historic data:

Raw and reduced data: While raw data is always stored on the measurement unit for an in-depth analysis, Historian takes the role of long-term reduced data storage into the cloud database.
Data safety and retransmit: If the connection between the measurement hardware and the database is lost, the data is safely stored locally on the measurement unit and then retransmitted to the database when the connection is available.
Trending and Analysis: Historical data can always be recalled and loaded from the Historian database and used for trend analysis as well as for in-depth analysis and root cause identification.
Web client: The web client interface is accessible from any web browser, making it a cross-platform and mobile solution. It provides an overview of the most important machine health data and its trend over time.
Alarm and alert levels: Alarms and alerts can be set on each display and tied to email/SMS notifications.
