SENCTRL 0-15 Psi Silicone Oil Filled Fuel Pressure Gauge
The SENCTRL Y.4 stainless steel case pressure gauge offers exceptional quality, durability, and performance. The inside of the gauge is filled with silicone oil which allows to use it under severe conditions accompanied by vibrations and pulsations. An ideal choice for satisfying most applications and installation requirements.
- 1-1/2" dial size, 1/8"NPT back mount
- Pressure Ranges: 0-15 psi
- Brass and stainless steel wetted parts, silicone oil filled
- For pressure measuring of gas, liquid which is not corrosive to brass.

Robust design
Stainless steel case pressure gauge offers exceptional quality, durability, and performance.

Vibration and shock-resistant
Silicone oil filled provides superior resistance to shock, vibration and pulsation; extends product life and reduces maintenance costs.

IP67 grade waterproof
Prevent water infiltrating and fogging of the window. Provide a clear reading.

Why Liquid Filled?
- The liquid filling dampens vibration, mechanical shock, and pressure pulsations, enabling easier pressure readings.
- The liquid filling eliminates corrosion, moisture penetration and icing due to the ambient atmosphere.
- The liquid filling lubricates all moving components, dramatically reducing wear of the movement.
How to choose the right scale range?
- The user must ensure that the appropriate pressure gauge has been selected in terms of scale range and design. The scale range is optimally selected when the operating pressure lies in the middle third of the scale range.
Where are liquid filled pressure gauge used?
Examples include:
- Pressure washers and sprayers
- Paint spray equipment
- Compressors
- Irrigation equipment
- Hydraulic systems
- Hydraulic hand tools
Instructions of a pressure gauge vent plug:
- For =300 psi pressure ranges, gauges require some type of vent valve, compensating membrane, or other mechanism for pressure compensation. Otherwise, changes in ambient temperature such as direct sunlight would distort the measured pressure. (No compensation is necessary in gauges with >300 psi pressure ranges, as the pressure built up inside the case is negligible in relation to the full scale range.)
- All pressure gauges sealed for the purpose of liquid-filling have a device to assure atmospheric compensation. To correctly vent the solid rubber fill plugs, simply cut off the tip of the plug which will open a small hole through so the gauge can vent. Only for mounting the gauge in a upright position.
