Features

  • Stainless steel case <improved contact durability>
  • Sealing of pure glycerin liquid <improved pulsation effect>
  • Safety mark provided as the standard
  • 270-degree pressure angle indications for improved clarity.
  • This gauge can be mounted directly onto the pressure port of the modular type hydraulic circuit.
  • he pressure gauge root section is equipped with special slots for absorbing pulsating pressure and surge pressure.
  • Even of modular valves are stacked, pressure gauges do not make contact with each other.
  • Movement of the pointer due to mechanical vibration is absorbed by the viscous drag by pure glycerin liquid in the hermetically-sealed pressure gauge. Movement of the Bourdon tube is also absorbed, improving the absorption effect of the pulsating pressure of the fluid.
  • The pure glycerin liquid serves as lubricating oil for the friction part of the bearing and gear in the pressure gauge, thereby further improving the durability of the internal mechanism in comparison with the existing products.
  • Safety measures are provided to ensure that the transparent sheet at the front is not shattered, and hydraulic oil is purged from the safety valve in the case that the Bourdon tube is broken.
  • The green safety mark attached to the circumference of the transparent sheet assists in the setting of a pressure range and values.
  • Select a pressure gauge whose top pressure reading is more than double the applicable pressure range.

How to use the safety mark

Instruction for use

  • The glycerin pressure gauge should be mounted vertically; otherwise an indication error or leakage of glycerin liquid may occur.
  • We do not offer glycerin pressure gauge with a special hand-written graduation.
  • All the safety marks are set to zero positions at shipment.
  • The transparent sheet at the front is made of polycarbonate (PC). Avoid direct contact of the sheet with any organic solvent. When painting, cover with a polyethylene bag.
  • Before use, remove the tip of the safety cap of the glycerin pressure gauge up to the 1MPa indication.
  • As there is little torque of the Bourdon tube in pressure gauges of less than 1MPa, When the torque of the Bourdon tube in the pressure gauge up to the 1MPa indication is small, the temperature change (internal pressure change) in the gauge case will affect the indication accuracy. By removing the tip of the safety cap, a balance between the internal pressure and atmospheric pressure can be maintained, thereby preserving accuracy. After removing the safety cap tip, make sure that the safety cap faces upwards to prevent leakage of glycerin liquid.
