Tokyo Ryuki Kogyo DPG-7000 Pressure Gauge

The differential pressure between the high pressure side and the low pressure side is received by the diaphragm of the indicator, and the movement is mechanically swung by the internal cam mechanism to indicate the differential pressure.

Description

The differential pressure between the high pressure side and the low pressure side is received by the diaphragm of the indicator, and the movement is mechanically swung by the internal cam mechanism to indicate the differential pressure. An alarm can be output by the contact with a micro switch, and it can be used for detecting clogging of equipment.

Model Number

  • DPG-7000 (without contacts, standard type)
  • DPG-7000S (with 1 contact)
  • DPG-7000S2 (with 2 contacts)

Brand

Ryuki Kogyo

Tokyo Ryuki Kogyo

Tokyo Ryuki Co., Ltd., a manufacturer of industrial flow meters and fluid-related equipment. For many years, we manufacture and sell products such as differential pressure type flow meter, area type flow meter, flow switch, metal tube type flow meter, galvanometer, level meter, and measuring pot.

Features

  • DPG-7000 type is a differential pressure gauge originally developed for gas and liquid.
  • Since the mechanism of the indicator is in the atmosphere, there is almost no corrosion by fluid.
  • The pressure receiving part uses a diaphragm (rubber with cloth).  Intensity, temperature characteristics and chemical resistance are sufficient for general use.
  • This product is designed to have a large pressure receiving area and to measure with high accuracy.
  • With 1 contact and with 2 contacts is a micro switch (C contact) method.  (Mechanical and error-free. Can be set freely within the scale range)
  • The high voltage side can be specified on either the left or right side.
  • For gas, please consider using a surge tank.
    (Countermeasures against vibration and pulsation)
    * A surge tank is a tank that reduces pulsation in the pipe and reduces the vibration of the pointer. (For gas)  One can be installed on the high pressure side and one on the low pressure side of the pressure guiding tube. Please contact us for details.
  • For options such as various fittings, valves, pressure guiding tubes, and flexible hoses, see the materials.
