How to use a multifunctional process calibrator?

The steps for using the multifunctional process calibrator are as follows:

1.Preparation work

  • Check whether the multifunctional process calibrator is damaged or has other abnormal conditions, and confirm whether the power supply and voltage are compatible. Choose the appropriate calibration module, the multifunctional process calibrator has multiple calibration modules to choose from.

2.Connected Device

  • Connect the multifunctional process calibrator to the device to be verified, and choose different interface methods according to different devices. Commonly used ones include handheld interfaces, clip on connectors, etc

3.Set verification parameters

  • Set corresponding calibration parameters based on the parameters of the device to be verified, such as calibration range, calibration point count, calibration accuracy, etc. When setting up, attention should be paid to selecting appropriate calibration modes, including manual mode and automatic mode.

4.Start verification

  • After entering the verification state, select the corresponding calibration point for verification according to the prompts of the multifunctional process calibrator. When conducting calibration, it is necessary to follow the calibration procedures of the equipment to ensure accurate and reliable test results.

5.Complete verification

  • After the verification is completed, the multifunctional process calibrator will automatically calculate the verification result. Save the verification data to the memory or external storage device of the multifunctional process calibrator for future reference and analysis.

The functions and application scenarios of multifunctional process calibrators:

  • Multi functional process calibrators are instruments and equipment used for testing, calibrating, inspecting, and diagnosing various on-site instrument signals and control systems. It can detect signals such as pressure, temperature, flow rate, and resistance in instruments, and is widely used in fields such as chemical engineering, metallurgy, power, and light industry.

  • Specific functions include direct current voltage (DCV) measurement and output, alternating current voltage (ACV) measurement, frequency measurement and output, resistance measurement and output, thermocouple and thermal resistance measurement, etc.

Precautions for use:

  • During use, safety should be taken into account to ensure that equipment and personnel are protected. For hazardous equipment such as high pressure and high temperature, corresponding safety measures should be taken before calibration.

  • When using a multifunctional process calibrator, one should avoid immersion in water, moisture, heat, or use in harsh environments such as vibration, dust, and corrosion to ensure the stable operation of the equipment.

  • During calibration, it is necessary to strictly follow the calibration procedures of the equipment to avoid errors caused by misoperation or improper operation.

Pressure Transmitter FAQ

What is a pressure transmitter used for?

A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.

How do I choose the right pressure transmitter?

Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.

What is the difference between gauge, absolute and differential pressure transmitters?

Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.

Can Xinyi Instrument provide customized pressure transmitters?

Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
