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 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.
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.
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.
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.
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 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.
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.
While grounding can prevent and resolve many power issues, it can also create serious issues of its own. One of the most common problems is known as ground loop feedback--often resulting when different electrical circuits are powering a system and its peripherals. This can also be a seasonal issue as hot dry temperatures can create signal noise for equipment end users, so the Application Specialists at CAS DataLoggers have put together this brief introduction to help reduce o...
Recent local, state and federal mandates such as RICE NESHAP require the reduction of harmful emissions (both particulate and NOx) from diesel engines used in off-road equipment, generators and more. After the emissions reduction equipment has been installed, it’s also necessary to monitor engine performance. Authored by CAS DataLoggers, this paper will review the datalogging requirements for this application, the sensors required, and sensor mounting considerations.
