5. Application Scenarios

Measuring range: 0～3 MPa (30 bar), G3/8 thread, Φ100 flush panel mounting. Suitable for medium & low-pressure hydraulic, pneumatic and water supply equipment, categorized by industries as follows:

(1) Hydraulic Equipment

• Small injection molding machines & vertical injection molding machinesMonitor low-pressure mold clamping, ejector oil pressure and low-pressure injection circuits. The 3 MPa measuring range perfectly matches low-pressure preloading oil lines.

• Hydraulic power units for machine toolsClamping pressure for grinders, milling machines, punch presses and hydraulic fixtures. Tool clamping pressure is mostly within 1～2.5 MPa.

• Hydraulic lifting platforms & small hydraulic jacking equipmentLow-pressure oil pressure indication and overload early warning for lifting loads.

• Rubber vulcanizers & small hydraulic hot pressesLow-pressure mold closing pressure monitoring for platens.

(2) Pneumatic & Air Compressor Systems

• Small screw air compressors & piston air compressorsLow-pressure supply pressure after secondary pressure regulation (standard factory supply pressure: 0.5～0.8 MPa with sufficient range margin).

• Air receivers & pneumatic control cabinet panelsMain pipeline pressure monitoring for centralized workshop air supply. Flange flush mounting adapts well to cutouts of electric control cabinets.

• Automated pneumatic production lines & cylinder booster circuitsLow-pressure output pressure indication of booster valves.

(3) Water Treatment, Water Supply & Cleaning Equipment

• Water purifiers & RO reverse osmosis equipmentPressure monitoring for low-pressure pretreatment pipelines (raw water and pre-filter pressure generally 1～2.5 MPa).

• Low-pressure inlet side of small high-pressure cleaners & pipeline booster pumpsInlet pressure stabilization monitoring.

• Building secondary water supply & small water supply booster unitsPressure monitoring for domestic water pipelines.

(4) Rubber, Plastic & Packaging Machinery

• Cooling water circuits of film blowers & extrudersWater pressure monitoring for cooling circulation pipelines.

• Automatic packaging machines, labeling machines & pneumatic sealing machinesPanel display of air source pressure for complete equipment.

• Low-pressure air supply circuits of foaming equipment.

(5) General Industrial Supporting Facilities

• Cooling water circuits for boiler auxiliary equipment & small heat exchange stationsLow-pressure pressure monitoring of circulating water.

• Cooling circuits & mold water lines of die-casting machines

• Laboratory test benches & small hydraulic test toolingAccurate observation for low-pressure testing within 0～3 MPa.

• Auxiliary low-pressure oil circuits of construction machineryHydraulic auxiliary circuits for small agricultural machinery and compact construction equipment.

6. Selection Advantages

• Large Φ100 dial ensures legible readings from a distance; standard configuration for workshop equipment panels.

• Rear flange flush mounting enables direct installation on control cabinets / equipment panels for neat appearance.

• G3/8 thread is widely adopted in hydraulic and pneumatic systems with high compatibility for pipeline fittings.

• 0～3 MPa range covers most medium/low-pressure water, gas and oil working conditions; an excessively wide measuring range will lead to poor reading accuracy.

• TOKO pressure gauge suppresses slight pressure pulsation and avoids frequent pointer vibration under vibration generated by oil pumps and air compressors.
