Choosing a Water Level Logger: 5 Things You Should Know

While water level loggers have become the data collection instrument of choice for an increasing number of hydrologists, the product choices available today can make it difficult to determine which product is right. This report from CAS DataLoggers can help you choose the right products for your needs.

PID Control with ADwin

One of the most common automatic control methods is the Proportional-plus-Integral-and-Derivative (PID) controller. In this white paper CAS DataLoggers shows how the architecture of ADwin data acquisition and control systems makes them well-suited for PID applications.

Measuring Voltage and Current Using a Data Logger

A common data logging application is measuring voltage or current flowing into or out of a piece of equipment. These measurements can be broadly classified into two groups: AC and DC. At CAS DataLoggers we've put together this brief guide covering the basics of voltage and current measurement.

SDI-12: The Technology Behind Smart Sensors

SDI-12 has become the environmental standard of choice for environmental monitoring applications. At CAS DataLoggers we’ve put together this brief introduction to the SDI-12 standard highlighting the advantages your business or organization can realize from using SDI-12 data loggers and sensors.

The 6 Most Important Parts of a Temperature Monitoring System

You may know that you need a temperature monitoring system but aren’t sure how to purchase or use one. At CAS DataLoggers we’ve put together this basic tutorial covering the 6 parts to a typical Temperature Monitoring System so you can choose which is best for your application.

Comparison of Thermal Buffer Effectiveness

Abstract: Experimental data was collected to examine the behavior of RTD probes in various thermal buffers in refrigerator and freezer applications. From the warm-up time vs. temperature curves, a thermal time constant was determined by fitting an exponential line to the data. Also, the behavior of the buffers during typical operation as the refrigeration compressor cycled on and off was observed. Using this data, recommendations on buffers for refrigerators and freezers are made.

Basic Techniques for Accurate Resistance Measurement

At CAS DataLoggers we often receive calls from users working in resistance measurement applications, for example using string pots to measure movement, measuring thermistors/RTDs for temperature, measuring the resistance on test samples, and many more applications. In this white paper, we’ll cover a few simple ways you can reduce error and improve accuracy at the low, mid- and high resistance ranges.

What is The Internet of Things?

The Internet of Things (IoT) is a popular phrase for the increasing development and market saturation of Internet-capable physical objects such as appliances and control systems. CAS DataLoggers covers several industry opportunities presented by today’s wireless dataloggers including models with new mobile apps which let users remotely monitor temperature and control processes from anywhere.

What is a Data Logger?

What is a datalogger? These products are widely-used measurement and data storage tools that monitor your product or process 24/7. Using a data logger you can keep an eye on temperature, humidity, current/voltage or just about any kind of data. In this article the Application Specialists at CAS DataLoggers walk you through the basics of data loggers and what they can do for your business or organization.

Self-Calibrate Your Thermistors for Higher Accuracy

Technicians and engineers often use thermistors to log temperature in applications which require increased accuracy for more demanding projects. To accomplish this, they use the Steinhart–Hart equation to get much more precise readings across the sensors’ temperature ranges. Users most commonly work with it in applications measuring water or machine temperatures. As part of our free tech support, we at CAS Data Loggers often provide help in this area for customers.
