Double pistons deadweight tester
The dual-piston pressure gauge is mainly used for calibrating pressure sensors, pressure transmitters, digital pressure gauges and other precision pressure instruments. It can also be used to calibrate mercury pressure gauges, various non-corrosive industrial pressure gauges or other types of precision pressure measuring instruments. It is characterized by wide measuring range, large measuring range, sharing a set of weights, saving purchase cost, and widely used in industrial and mining enterprises such as petroleum, chemical industry, smelting, coal mine, ship, instrument and so on.
Product introduction

Wide range and multiple precision options

A variety of measurement ranges and accuracy levels are available for users to choose freely.

One host is equipped with two sets of piston systems with independent ranges at the same time, which can effectively widen the measuring range of the instrument, ensure the measuring accuracy, and save laboratory space. When using one of the range accuracy, the other set of piston system is automatically in the protection state, and there is no need for cumbersome valve switching.

Product series: YDT5000 series double piston pressure gauge

Measuring range: (0~110)MPa

 

YDT double-piston pressure gauge is mainly suitable for calibrating pressure sensors, pressure transmitters, digital pressure gauges and other precision pressure instruments. It can also be used to calibrate mercury pressure gauges, various non-corrosive industrial pressure gauges or other types of precision pressure measuring instruments. It is characterized by wide measuring range, large measuring range, sharing a set of weights, saving purchase cost, and widely used in industrial and mining enterprises such as petroleum, chemical industry, smelting, coal mine, ship, instrument and so on.

 

Features:

Measurement range: (0.04~35) MPa, (0.1~70) MPa, (0.1~110) MPa (other special measurement ranges need to be confirmed by us) 

Accuracy level: 0.05, 0.02, 0.01, 0.005 

Each weight has an adjustment cavity, which is convenient for periodic inspection and adjustment 

With pre-compression function, it is easy to pressurize at high pressure 

The piston cylinder and piston cylinder are made of tungsten carbide and are carefuly ground 

Working environment temperature: (20±1), relative humidity: constant temperature room below 8% 

Each piston measuring system has an anti-break device, and users can use it with confidence 

The weight of the high-voltage measurement system adopts a hanging basket structure, with a low center of gravity, reducing the risk of segment rods 



High and low pressure automatic switching range, no valve switching

Two piston measuring systems share a set of weights

Verification standard: "JJG59-2007 Verification Regulations for Piston Pressure Gauge", "JJG99-2006 National Metrological Verification Regulations for Weights" 

Each piece of equipment can be delivered with a national statutory structural inspection certificate (confirm with us in advance if necessary)
