Current and voltage calibrators are portable precision calibrators designed to verify, adjust, or calibrate multiple measurement instruments. These instruments can calibrate a range of process devices like multimeters, transmitters, controllers, and other electrical testing equipment. A current and voltage calibrator generates or simulates electrical signals, typically either current or voltage, to test and verify the accuracy of these devices. Essentially, these test and measurement devices provide a standard reference output that can be used to ensure other instruments are reading correctly, maintaining the integrity and precision of any electrical system.
Why Buy Current & Voltage Calibrators? Exploring Their Benefits
Regular equipment calibration is essential for robust accuracy, reliability, and cost savings. Calibrators like current and voltage calibrators ensure the safety, accuracy, and reliability of testing instruments, avoid downtime, and minimise breakdowns or errors in the system. These calibrators are handheld devices with battery-powered models, ensuring convenience and easy portability for on-the-go applications. Additionally, current and voltage calibrators enable professionals to verify the performance and accuracy of their instruments, ensuring compliance with industry standards.
Types of Current and Voltage Calibrators:
Current and voltage calibrators are dual-function calibration equipment that come in different types, such as:
- AC & DC Voltage Calibrators – Voltage calibrators come in DC and AC versions, the latter of which is used to test AC measurement instruments.
- AC & DC Current Calibrators – Current calibrators, similar to voltage calibrators, come in AC and DC current calibrators. DC calibrators are designed to calibrate loop instruments, simulating DC currents.
Multifunction Calibrators and Loop Calibrators:
While current and voltage calibrators are still widely used, multifunction calibrators are preferred because they can generate both current and voltage and other types of signals, like resistance and temperature. Loop calibrators, on the other hand, are explicitly designed to work with 4-20 mA current loops. They can simulate or read current loop signals, which are common in process control industries.
Typical Applications of Current & Voltage Calibrators:
Current and voltage calibrators are widely used across various applications and facilities, such as:
- Industrial Automation and Process Control
- Calibration of Measurement Instruments
- Testing and Maintenance
- Quality Control Laboratories
- Maintenance of Safety Systems.
