YK-200 Digital Pressure Calibrator: An Efficient Integrated Solution for On-Site Calibration of Industrial Pressure Instruments
In process industries such as petrochemical, power, metallurgy, pharmaceutical, and water treatment, regular calibration of pressure gauges, pressure transmitters, pressure switches, and precision pressure instruments is a key link to ensure process control accuracy, safe operation, and metrology compliance. Traditional single-screen calibrators often suffer from inconvenient switching between pressure and electrical signals, resulting in low operational efficiency and easy confusion in readings.
The Nexisense YK-200 Digital Pressure Calibrator adopts a unique dual-screen independent display design. The upper row clearly displays pressure values, while the lower row synchronously displays current or voltage values, making readings clear and operation intuitive. The instrument integrates pressure measurement, electrical signal measurement, 24V loop power supply, and continuity testing in one unit. It can efficiently calibrate two-wire/three-wire pressure transmitters, pressure switches, and various pressure instruments, providing portable and precise on-site calibration solutions for metrology verification institutions and enterprise maintenance teams.

Verification of Pressure Gauges and Precision Pressure Gauges: Multi-unit switching function meets metrology standard requirements of different industries.
Pressure Switch Function Testing: Verify action and reset values through continuity signal detection to ensure reliable safety interlocks.
Comprehensive Verification of Two-Wire/Three-Wire Transmitters: Built-in 24V power supply and electrical signal measurement complete full-parameter verification of power supply, input, and output in one go.
Metrology Verification and Maintenance: Periodic calibration of petrochemical tank pressure monitoring systems, boiler pressure control systems, and pipeline transportation systems.
System Integration Support: Integrated as a standard tool into enterprise instrument maintenance platforms or EPC project on-site debugging processes.
In actual applications, this calibrator has helped many enterprises shorten calibration time, reduce wiring errors, and improve the traceability of metrology data.
Selection Guide and Integration Considerations
To ensure optimal performance, it is recommended to select and integrate according to the following points:
Accuracy Selection: 0.02 grade is suitable for high-precision requirements (such as precision pressure gauges and critical process control); 0.05 grade is suitable for routine on-site maintenance with better cost-effectiveness.
Pressure Range Matching: Select the appropriate pressure range according to the maximum range of the instrument being calibrated to ensure the working point is in the middle of the range for optimal accuracy.
Power Supply and Signal Requirements: Confirm whether the transmitter being calibrated is two-wire or three-wire, and use the built-in 24V power supply and current/voltage measurement functions for comprehensive testing.
Unit and Mode Settings: Before on-site calibration, switch pressure units according to metrology standards and select the appropriate electrical signal measurement mode (with or without excitation).
Integration Considerations:
Pay attention to sealing of the pressure interface during connection to avoid leakage affecting measurement accuracy.
When using 24V loop power supply, monitor the load current to ensure it does not exceed 30mA.
In dual-screen display mode, pressure changes and output signal responses can be observed simultaneously, facilitating judgment of instrument linearity and hysteresis.
Perform periodic traceability calibration on the calibrator to maintain its accuracy as a metrology standard.
For batch verification projects, common parameters can be preset in advance to reduce on-site repeated setting time.
