Bespoke Explosion Proof Stainless Steel Float Switch (F/S-FP)
Product Description
The Deeter F/S-FP is explosion proof float switch is a magnetic reed switch or Hall Effect sensor stem for control and indication of a liquid level while in a potentially explosive atmosphere.
Features include:
- ATEX and IECEx approved.
- Stainless steel 316L housing and wetted components.
- Custom length sensor stems up to 6 Metres.
- Up to 7 switch points on one stem.
- Custom made for mixed normally open/normally closed switches.
- Suitable for gas and dust environments.
- IP68 Ingress protection.
- Voltage free reed switch contacts or Hall Effect sensing technology.
- M20 or ½”NPT cable entry.
- Custom mounting options available.
- Narrow sensor stem and mounting for tanks without internal access.
- Suitable for high liquid pressures
- Can be specified for liquid temperatures down to -55°C
The F/S-FP explosion proof float switch holds ATEX & IECEx certification for use in most regions worldwide.
