The 4-20mA analog current loop is a widely adopted industry standard across numerous sectors. Its ease of use and cost-effectiveness in instrumentation equipment have led to its extensive application in various industries. The 4-20mA analog current signal is preferred for long-distance transmissions because, unlike voltage, its strength does not diminish over extended runs. The Portable 4-20mA Current Loop Meter CTV200 is specifically designed and manufactured for monitoring sensors with a 4-20mA analog current output.
Many industrial sensors, including those for temperature, pressure, level, flow, pH, and more, feature 4-20mA analog outputs. Consequently, measuring these sensor signals is crucial. Given its portability, the 4-20mA Signal Tester can be effectively utilized directly at the sensor’s installation site. One of its primary applications is in industrial facilities. With the widespread use of 4-20mA output sensors and transmitters in diverse environments, the 4-20mA Current Loop Meter enables on-site monitoring and testing of sensors, transmitters, and control equipment without the need to remove them from their installed locations. This industrial calibrator can also be used as a 4-20mA equipment calibrator in the petrochemical, oil & gas, water & wastewater industries, and within various control systems.
Given the widespread use of transmitters and sensors with 4-20mA analog outputs across various industries, monitoring these sensors is of paramount importance. The Portable 4-20mA Measurement Meter is designed and manufactured for on-site sensor monitoring. Utilizing the Portable 4-20mA Current Loop Meter enables sensor measurement, along with the ability to detect sensor malfunctions. A current reading outside the 4-20mA range indicates a sensor fault; specifically, a current display of less than 3.8mA or greater than 20.5mA is considered an error.
The Portable 4-20mA Measurement Meter can be employed in various environments. In orchard settings that use various equipment and sensors—such as pressure, temperature, level sensors, etc.—with 4-20mA outputs, this portable meter enables convenient sensor monitoring in their installed locations.
If 4-20mA signal measurement and testing are needed in industrial environments but portability is not required, non-portable 4-20mA measurement instruments are available. These units can be mounted in electrical panels and are suited for industrial applications in production lines and control rooms. The 4-20mA Analog Input Card features eight 4-20mA measurement ports and supports Modbus and Ethernet protocols. The Multi-Function Network IO Expansion Card offers four 4-20mA measurement ports, along with several digital inputs and outputs, and supports Modbus, Ethernet, and cellular connectivity.
