Handheld Digital Process Calibrator

Details

Q1: What is a process calibrator?
A1: A process calibrator is a multifunctional device used to test, troubleshoot, and calibrate various process instruments in industrial settings. It is commonly used in industries like manufacturing, oil and gas, chemical processing, power generation, and more—essentially anywhere precise control and measurement of physical parameters (like pressure, temperature, current, voltage, frequency, and resistance) are required.

Q2: What Does a Process Calibrator Do?
A2: A process calibrator can:
Source signals: It can simulate input signals (e.g., 4-20 mA current loops, voltage, thermocouples, RTDs) to test the response of instruments. Measure signals: It reads and displays the output from sensors or transmitters to verify their accuracy. Simultaneously source and measure: Many calibrators can do both at once—for example, outputting a 4-20 mA signal to a device while also reading the mA feedback from a loop. Loop power: Some provide loop power to power up field transmitters during calibration.

Q3: How does a process calibrator work?
A3: A process calibrator is a multifunctional test tool used in industrial settings to simulate, measure, and source various process signals to calibrate and troubleshoot instruments.

• Simulation (Sourcing Mode): The calibrator mimics a sensor or transmitter: For example, it can output a 4-20 mA signal to test a control system input. It can simulate a thermocouple or RTD to test temperature controllers.
• Measurement Mode: The calibrator measures signals coming from sensors or transmitters: It can measure the output of a 4-20 mA transmitter. Or it can read thermocouple or RTD signals to verify temperature readings.
• Loop Power Supply: Many calibrators can provide loop power (usually 24V DC) to power a 2-wire transmitter during testing—handy when you’re not connected to the control system.
• Documentation and HART/Fieldbus Communication (in advanced models): Some calibrators support automatic documentation of calibration results. Others can communicate with smart transmitters (e.g., HART protocol) to adjust or troubleshoot them.

Tips: How to use a handheld digital process calibrator correctly?

1. Understand the basic functions: Before use, read the user manual carefully to ensure that you understand all the basic functions and operation buttons of the calibrator. This will help you perform calibration work more efficiently.
2. Regular calibration: To ensure the accuracy of the calibrator, self calibration should be conducted regularly or sent to a professional institution for calibration. The calibration cycle can be adjusted according to the frequency of use and environmental conditions.
3. Proper power management: Use a suitable power adapter or battery and ensure that operations are carried out with sufficient power. Replace the battery or charge it in a timely manner when the battery is low to avoid interruption of the calibration process or data loss.
4. Training and Education: Regularly attend relevant training courses to maintain an understanding of the latest calibration techniques and operating methods, and improve your professional level.
