Loop Calibrator

Loop Calibrator Home

Process loops are perhaps the most abundant feed back control systems in the world, these process loops are typically a low current signal scaled from 4 to 20mA DC. The objective of these loops is to transmit process values from a transmitter or transducer to a controller or display. The transmitter or transducer will regulate the flow of current in the process loop to indicate a value between zero (4mA) and full scale (20mA). In many cases the controller will use this information to regulate the process based on pre programmed values. To ensure that these process loops are accurate, a Loop Calibrator will be often used. A loop calibrator is often times called a 4-20mA calibrator or even a process loop calibrator. A loop calibrator in its most basic form does two things. It will measure the output of a 4-20mA transmitter/transducer and it will generate a known 4-20mA current. When calibrating a typical process loop, the loop calibrator is used to verify that the transmitter is putting out the proper values by measuring the existing 4-20mA signal and comparing the readings to the process. It is also used to supply a known loop value into the display or controller to ensure that the display/controller is reading correctly. Loop calibrators can be packaged in a stand alone instrument or they can be included in multifunction instruments that will also be able to read and generate other process signals (voltage, temperature, resistance, pressure...)

Mitchell Instrument Company Inc. has been selling Loop Calibrators for over 30 years, we offer an extensive lineup of loop calibrators as well as multifunction calibrators. Our goal is to provide a one stop shopping experience that combines expert technical expertise, quick delivery and competitive pricing!
