YWT Series Self-Weight Testing Piston Pressure Gauge – Adjustable
Pressure Range 1-250 MPa
Product Usage:
YWT series basic piston pressure gauges can measure pressures up to
100MPa, mainly used in metrological verification laboratories to
verify pressure instruments such as digital pressure gauges,
pressure sensors, pressure transmitters, precision pressure gauges
and ordinary pressure gauges. It is suitable for high-level
measurement institutions, pressure instruments, instrument
manufacturers and measurement departments of modern factories.
Features:
● Measuring range: 0.04~0.6MPa, 0.5~25MPa, 0.1~6MPa, 1~60MPa,
2~100MPa 2-160MPa 5-250MPa
● Accuracy level: 0.05, 0.02, 0.01, 0.005
● With pre-pressing function, it is easy to pressurize at high
pressure;
● The piston cylinder and piston cylinder are made of tungsten
carbide material with high strength, high hardness and low
temperature coefficient of linear expansion after careful grinding.
The working environment temperature is wide and the performance is
stable at 20±5℃;
● Oil medium lubrication, high sensitivity of piston;
● Super hard material, long service life of piston, negligible
pressure deformation;
● Manufactured according to the user's local acceleration of
gravity;
● Each weight has an adjustment cavity, which is convenient for
periodic inspection and adjustment;
● 12mm cast aluminum machine, strong and stable;
● All stainless steel pipe joints are well sealed and there is no
aging problem of plastic pipes;
● Adopt quick connector, easy to operate, easy to tighten without
wrench;
● The working position of the piston is monitored by a displacement
sensor, the up and down stroke of the piston is 0~3mm, and the
instrument display has the advantages of being sensitive,
eye-catching and accurate;
● Grade 0.05 is carbon steel weights, and grades 0.02 and above are
non-magnetic stainless steel weights;
● Verification standard: "JJG59-2007 Verification Regulations for
Piston Pressure Gauge"
"JJG99-2006 National Metrological Verification Regulations for
Weights"
