4-20 mA Measurement Resolution

Data Acquisition > 4-20mA Current Loop Don’t overlook a vital component that affects 4-20 mA measurement success: Measurement resolution. Measurements from sensors that have a 4-20 mA output are very common. Customers always ask how to connect them to a data logger or data acquisition system, which we describe in detail here. However, they often overlook a vital Read More

4-20 mA Current Loop Data Acquisition

Data Acquisition > Current One of the most common industrial measurements is 4-20 mA current loop data acquisition. Electrical noise, present in most industrial settings, makes measuring a sensor/transducer output as a voltage impractical—especially over long distances. The solution is to transmit the sensor/transducer output as a current signal (process current). This is achieved by Read More

How To Make 4-20 mA Current Loop Measurements

Data Acquisition > Current Additional Reading: 4-20 mA Current Loop Data Logger Products 4-20 mA Current Loop Data Acquisition Products It seems that at least one 4-20 mA (milliamp) measurement is required by our typical customer, and the way to do it is a constant source of confusion for many. So I thought I’d zero Read More
