Budenberg 480 Dead Weight Tester (without Weights)

The Budenberg 480 Dead Weight Tester (Without Weights) 

is a precision pressure calibration instrument designed for accurate generation and measurement of pressure as a primary standard. It is used for calibration of pressure gauges, transmitters, switches, and sensors in laboratories, workshops, and industrial maintenance facilities.

This model consists of the tester base assembly including:

• Precision piston-cylinder unit
• Pressure generation pump system
• Fine adjustment screw press
• Reservoir and pressure connection ports

Since this unit is supplied without weights, it does not include the calibrated mass set required to generate known pressure values. Users must use compatible original Budenberg calibrated weight sets matched to the piston serial number for proper operation.

The tester works on the dead-weight principle: known masses placed on a piston generate precise pressure based on force divided by piston area. Budenberg dead-weight systems are recognized as primary pressure standards due to their high repeatability and measurement reliability.

? Key Features

• High-accuracy primary pressure calibration standard
• Precision piston-cylinder pressure generation system
• Stable and repeatable calibration results
• Fine pressure adjustment for exact balancing
• Suitable for laboratory and field calibration work
• Rugged industrial-grade construction
• Compatible with Budenberg certified weight sets

⚙️ Applications

• Calibration laboratories
• Industrial instrumentation workshops
• Pressure gauge calibration
• Transmitter and sensor testing
• Process plant maintenance departments
• Metrology and quality assurance facilities

? Notes

• Supplied without calibrated weight masses
• Requires matching Budenberg certified weight set for operation
• Weight sets must correspond exactly to piston serial number
• Accuracy depends on proper gravity and environmental correction factors
• Suitable for hydraulic pressure calibration systems

? Simple Explanation

? This device creates highly accurate pressure for testing gauges, but without the weights included, it cannot generate calibrated pressure until the correct Budenberg weight set is added.
