Multi Functional Process Calibrator

Details

Q1: What is a Process Calibrator?
A1: A process calibrator is a device used to test, calibrate, and troubleshoot process instrumentation such as temperature sensors, pressure transmitters, and electrical signal sources. By simulating and measuring various signals, process calibrators enable engineers and technicians to validate system performance.

Q2: What are the types of process calibrators?
A2: Multifunction Calibrators - Capable of handling multiple types of signals including voltage, current, resistance, and frequency. Temperature Calibrators - Used specifically for thermocouples and RTDs to ensure precise temperature measurements. Pressure Calibrators - Designed for testing pressure-based instruments and ensuring accuracy in fluid systems. Loop Calibrators - Primarily used for 4-20 mA control loops in industrial automation systems.

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: When using the process calibrator, the following precautions should be taken:

1. Safe operation:
Prevent electric shock: Ensure good grounding of the equipment, avoid operating in humid environments, and be careful to avoid contact with exposed metal parts during operation. Avoid overload: The input signal should not exceed the device range to prevent damage. Prevent damage: In case of abnormalities (such as smoking, odor), immediately turn off the power and checkCorrect use Environmental requirements: Operate at appropriate temperature and humidity, avoiding strong magnetic fields, strong vibrations, and other interferences.
2. Correct connection:
Ensure good contact of the connecting wires, pay attention to the correspondence and polarity of the interfaces. Function and range selection: Select appropriate measurement functions and ranges according to requirements to ensure measurement accuracy.
3. Maintenance:
Regular calibration: Calibrate on time to ensure the accuracy of measurement results. Cleaning and maintenance: Keep the equipment clean and dry, and avoid using chemical cleaning agents. Storage environment: When not in use for a long time, store in a dry, ventilated, and non corrosive gas environment. Following these precautions can effectively ensure the accuracy and reliability of the process calibrator, and extend its service life.
