Description
1. Introduction to Dead Weight Tester MT-L100DW
The Dead Weight Tester MT-L100DW is a high-precision pressure calibration instrument designed for laboratories, manufacturing facilities, and quality assurance applications. It is a primary standard pressure device that provides reliable and accurate reference pressure for testing and calibrating pressure gauges, transmitters, and sensors. This instrument is suitable for both high-pressure and low-pressure calibration, allowing users to maintain stringent accuracy standards in industrial and laboratory environments.
The MT-L100DW is engineered to support dual synchronous gauge testing, meaning two pressure gauges can be tested at the same time, increasing operational efficiency. Its design combines a robust anti-breakage piston and rod structure, a high-capacity oil reservoir for pump priming, and the ability to calibrate multiple gauges along extended pipelines, making it an essential tool for pressure calibration professionals.
2. Key Features and Functional Advantages

3. Working Principle and Operation
The Dead Weight Tester MT-L100DW operates on the classic dead weight principle, which uses calibrated weights to generate precise pressures:
-
Weights Application
Standardized masses are placed on a piston to generate a known force. -
Pressure Transmission
The force is transmitted via a piston-cylinder system filled with hydraulic oil or other suitable fluids. -
Gauge Testing
The applied pressure is transmitted to the gauges under test, allowing precise calibration against the known reference pressure. -
Display and Measurement
A built-in LCD displays piston displacement, which can be used for fine adjustments and verification of pressure applied.
This method ensures high accuracy because the applied pressure is directly determined by the mass of the weights and local gravity, minimizing dependency on electronic sensors or external calibration.
4. Medium Compatibility
The MT-L100DW is compatible with a variety of hydraulic fluids, making it versatile for different calibration applications:
-
Mixed Oil for Pressures Below 250 bar
-
Sebacate Oil for Pressures Equal or Above 250 bar
-
Kerosene-Based Oils
-
Transformer Oils for Specific Industrial Applications
Users can select the appropriate working medium based on pressure range, temperature, and fluid properties to ensure optimal performance.
