Product Overview
The JC-YFT-Q Portable Pneumatic Pressure Calibration Pump is designed to generate both positive air pressure and vacuum for testing and calibrating pressure instruments.
With a pressure range from -0.095 MPa vacuum to +6 MPa positive pressure, this manual pump provides a versatile pressure source for checking pressure gauges, pressure transmitters, pressure sensors, and pressure switches.
The pump uses clean, dry air as the transfer medium, eliminating the need for hydraulic oil or other liquid media. Its integrated fine adjustment valve allows operators to adjust the output pressure gradually and reach the required test points.
Equipped with two test ports, the pump allows a reference pressure instrument and a device under test to be connected for comparative testing.
Its compact desktop structure and approximately 4.5 kg net weight make it suitable for laboratory testing, workshop inspection, and on-site instrument maintenance.
Applications
The JC-YFT-Q pneumatic calibration pump provides a manual pressure and vacuum source for testing and calibrating various pressure instruments.
Pressure Gauge Calibration: Generates positive or negative pressure for checking mechanical and digital pressure gauge readings against a reference instrument.
Pressure Transmitter Testing: Provides a controlled pneumatic pressure source for verifying transmitter measurements.
Pressure Sensor Testing: Supports pressure measurement verification using a suitable reference instrument.
Pressure Switch Testing: Applies pressure or vacuum to check pressure switch operating points, where supported by the switch configuration.
Vacuum Gauge Testing: Generates vacuum for checking vacuum gauges and compound pressure gauges.
Laboratory and Workshop Testing: Provides a portable pressure source for routine instrument inspection and comparative testing.
On-Site Instrument Maintenance: Supports field testing without an external electrical power supply.
