Piston Type Pressure Gauge

YS series piston-type pressure gauge

Product Overview

YS series manometer is designed and developed by our manufacturer according to state' s latest calibration requlations of piston-type manometer and JJG59-2007 reauirements. It is a standard manometer of high accuracy, high reproducibility and high reliability. It is designed based on Pascal law and balance theory of hydrostatics. Piston-type manometer is always simply called manometer or pressure scale. It is mainly used in measure room, laboratory or applied as standard instrument during production or scientific experiment. It also can be used for detection of other instruments during detection procedure demanding highreliability.

Function and Features

1. Through elaborate polishment, piston and piston rod are all made of scleroid alloy of tungsten carbide material which is of high endurance, high hardness, coefficient of linear expansion in low temperature. Its features are low expansion factor, little deformation, so the rate of change of piston efficient area is low ano t is stable and well adaptive to various environment2. Because of new material, new technology, new processing, the new piston-type manometer gets improvec in many aspects of technical index. Thus, it is widely used for calibrating digital pressure gauges, accurate pressure gauges, pressure transmitter. pressure transducer, eto3. Weights can be directly added on piston via weight frame due to low loading center of gravity. The piston moves stably and pressure barely waves and the value is correct4、 The pressure medium above 25MPa is di-iso-octyl sebacate of low viscosity which can keep the manometer highly sensitive5, All the weights are made of nonmagnetic stainless steel. (weight of 0.05 is made of carbon steel)6, Woking position of piston is detected by displacement sensor. Upper and lower distance is 1.5mm. The instrument obviously is sensitive, distinct and accurate.7. Wide measuring range, at 1MPa of lower limit, the basic error is +0.01%、 ±0.02%、±0.05%, ±0.05% 8, Function: value-transmitting piston-type manometer, calibrating digital manometer, accurate pressure gauge and pressure transducer, etc9, Material of piston: alloy of high hardness (tungsten carbide)10. Material of weights: stainless steel: carbon steel11. Working medium: transducer oil or the mixture of transducer oil and kerosene oil if the pressure is below 25MPa: di-iso-octyl sebacate if the pressure is above 25MPa.

Knowledge of daily maintainance and reparation

1. Keep the pressure gauge clean, do not put it in high-temperature environment in case of corrosion 2, Quick connect and O-ring beneath piston are vulnerable, replace it if there is leakage3. Liquid level inside oil cup should always be above the face of filter hood. Air moves into the prepressing pump because of lapse of attention, resulting in ineffectiveness of the pump. Then, screw off the connect or prepressing pump, making the air flow out with the liquid. The the liquid flow out without interruption, screw tight the connect and recover the function of pump.

A Piston Type Pressure Gauge is a type of mechanical pressure gauge which uses a piston and cylinder mechanism to measure the pressure of a fluid or gas. The piston moves within the cylinder in response to changes in pressure, and the resulting displacement is used to indicate the pressure reading on a calibrated scale.

These gauges are commonly used in industrial and automotive applications where high accuracy and durability are required. They can be used to measure pressure in a variety of mediums, including gases, liquids, and steam.

Piston type pressure gauges are known for their high precision, reliability, and rugged construction. However, they can be more expensive than other types of gauges, and may require more frequent calibration to maintain accuracy over time.
