The IFM E30148 Protective Cap is a closed vent cap designed to protect the atmospheric vent of compatible pressure sensors. It is intended for applications where a closed vent arrangement is appropriate, particularly at pressures of 25 bar and above or where the application temperature remains constant. The cap is manufactured from stainless steel 1.4404 / 316L.
Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E30148 provides a closed vent arrangement for compatible pressure sensors. It can be used when the atmospheric vent does not require conventional open venting. This helps protect the sensor from external contamination entering through the vent. The application conditions must be suitable for a closed vent configuration.
IFM recommends the E30148 for applications above 25 bar. It is particularly useful when the operating conditions provide a stable application temperature. This makes it a practical accessory for selected high-pressure pressure-sensing installations.
The cap is manufactured from stainless steel 1.4404 / 316L. This provides a robust mechanical enclosure suitable for demanding industrial environments. Stainless-steel construction also supports durability during installation and service. The material should be evaluated against the specific environmental conditions.
The protective cap is screwed onto the compatible pressure sensor filter connection. IFM specifies a recommended tightening torque of 2.5–3.5 Nm. Correct torque helps ensure secure installation without damaging the component. The cap is supplied as one piece.
