三、结构与特点
甘油充油阻尼：抑制设备振动、压力脉动造成指针抖动，同时润滑机芯齿轮，延长使用寿命，适合液压站、工程机械、注塑机等有振动的油压回路。
外壳为 A 型圆売无外缘，Φ60 紧凑尺寸，机床液压系统常用。
表壳上部带有泄压橡胶塞（运输、温度变化平衡内部压力，请勿拔出）。
四、适用场景
机床液压单元、注塑机、油压夹具、通用液压系统油压监测
有振动、压力脉动的油压管路
室内工业设备（不建议户外暴晒高温）
五、选型 & 采购注意事项
螺纹区分：G1/4（PF1/4 圆柱）≠ R1/4 圆锥，订货确认螺纹，错配会发生泄漏。
介质提醒：
使用水乙二醇介质：甘油版本不推荐，应选择硅油充油版本；
腐蚀介质：需要 SUS316 接液的 AT‑S 不锈钢系列，不能用 NSPA 黄铜机芯。
温度＞60℃环境，甘油粘度会劣化，指针阻尼失效，务必改用硅油充油型号。
运输：该表属于充油仪表，需直立防振包装，禁止倒置长时间储运，防止充油溢出。
可选定制：红黄绿警戒色刻度盘、禁油洗净仕様。

TOKO (Toyo Keiki Kogyo) Pressure Gauge Model NSPA‑G1/4‑60×40MPa Glycerin‑Filled Vibration‑Resistant Pressure Gauge
I. Complete Model Code Breakdown
| Model Segment | Description |
|---|---|
| NSPA | Radial bottom‑mount series, glycerin‑filled vibration‑resistant pressure gauge (suffix‑V indicates glycerin filling inside gauge) |
| G1/4 | Process connection thread: G1/4 (PF1/4), 55° non‑sealing parallel pipe thread, radial bottom outlet connection |
| 60 | Dial outer diameter Φ60 mm, Type‑A non‑flanged case |
| ×40MPa | Pressure range: 0～40 MPa |
Complete standard ordering model: NSPA‑G1/4‑60×40MPa‑V.‑V = Glycerin filled (vibration‑resistant with glycerin). Suffix‑V may be omitted on some labels.
II. Core Technical Specifications (Compliant with Japanese Standard JIS B7505 for Pressure Gauges)
| Item | Specification |
|---|---|
| Pressure Range | 0‑40 MPa |
| Accuracy Class | ±1.6 % F.S. (Full‑Scale accuracy) |
| Case | SPCC chrome‑plated steel case |
| Wetted Parts | Socket: Brass; Bourdon tube: Copper alloy. Not suitable for highly corrosive media |
| Fill Fluid | Glycerin |
| Operating Temperature | Ambient temperature: ‑15～+60 ℃. Glycerin is not suitable for high‑temperature environments; select silicone‑oil‑filled version for temperatures above 60 ℃ |
| Mounting Style | Radial direct bottom‑mount; panel flush‑mount is not supported |
| Dial Unit | Single metric scale in MPa |
| Compatible Media | Non‑corrosive fluids such as hydraulic oil and lubricating oil. Not for high‑temperature water‑glycol service. Specify special oil‑free cleaning requirement for oil‑free applications |
| Over‑Pressure Safety | Short‑term overload ≤125 % FS. Continuous operation at full‑scale 40 MPa is prohibited. Recommended normal working pressure ≤ 2/3 full scale ≈26‑27 MPa |
III. Construction & Features
Glycerin‑filled damping: Suppresses pointer flutter caused by equipment vibration and pressure pulsation. Lubricates internal movement gears to extend service life. Suitable for vibrating hydraulic circuits such as hydraulic power units, construction machinery and injection‑molding machines.
Type‑A round case without front flange; compact Φ60 mm size, widely used for machine‑tool hydraulic systems.
Pressure‑relief rubber vent plug on top of case (balances internal pressure during transportation and temperature change; do not remove the plug).
IV. Applications
Hydraulic pressure monitoring for machine‑tool hydraulic units, injection‑molding machines, hydraulic fixtures and general‑purpose hydraulic systems
Hydraulic piping with vibration and pressure pulsation
Indoor industrial equipment (not recommended for outdoor exposure under direct sunlight and high heat)
V. Selection & Procurement Notes
Thread distinction: G1/4 (PF1/4 parallel thread) ≠ R1/4 taper thread. Confirm thread type when placing orders; mismatched threads will cause leakage.
Media recommendations:
For water‑glycol media: Glycerin‑filled version is not recommended; select silicone‑oil‑filled variant.
For corrosive media: Use AT‑S stainless‑steel series with SUS316 wetted parts; do not use NSPA with brass movement.
For ambient temperature > 60 ℃: Glycerin viscosity degrades and pointer damping fails. Must switch to silicone‑oil‑filled model.
Transportation: This liquid‑filled gauge shall be packed with anti‑vibration protection and kept upright. Long‑term inverted storage/transport is forbidden to prevent fill‑fluid leakage.
Optional customizations: Red‑yellow‑green warning‑zone dial marking, oil‑free cleaning treatment.
