High Accuracy Corrosion Resistant Vibration Fork Level Switch

Technical Specifications

Product Application

The MG8400 Series Vibrating Fork Level Switch is designed for reliable level control of liquids, slurries, powders, and solid particles in both open and pressurized vessels. Featuring maintenance-free operation, no on-site calibration, and immunity to flow rate, foam, and agitation, it provides accurate switching signals across extreme process conditions. With IP67/IP68 protection, NEPSI, CNEX and SIL certifications, and wetted parts in 316L stainless steel or Hastelloy C-276, the MG8400 is ideal for hazardous and corrosive industrial environments.

Oil & Gas Industry

In oil and gas processing, the MG8400 is used for level control in storage tanks, separators, and process vessels containing petroleum, liquefied gas, and hydrocarbon slurries. Its explosion-proof certifications ensure safe operation in hazardous areas, while the tuning fork design remains unaffected by turbulent flow or vibration from nearby equipment.

Key advantages:

• NEPSI / CNEX / SIL hazardous area compliance

• Unaffected by medium flow rate and vessel vibration

• Wetted materials: 316L SST / Hastelloy C-276

Chemical & Petrochemical Industry

In chemical processing, the MG8400 handles level detection of aggressive media including acids, alkalis, and corrosive solvents. The highly polished fork minimizes material adhesion, and the all-welded construction prevents leakage. It performs reliably in reactors and mixing tanks where foam and agitation are present.

Key advantages:

• Corrosion-resistant wetted parts: 316L / titanium / Hastelloy C-276

• Immune to foam and gas-phase composition changes

• Operating pressure up to 6.3 MPa (63 bar)

Food & Beverage Industry

In food and beverage production, the MG8400 monitors liquid levels in tanks containing beverages, beer, and aqueous solutions. The stainless steel sanitary construction and maintenance-free design meet strict hygiene requirements, while the clear LED red/blue indication simplifies on-site monitoring.

Key advantages:

• 316L stainless steel hygienic construction

• Maintenance-free, no calibration required

• Clear LED red/blue on-site indication

Power Industry

In power plants, the MG8400 provides level control for boiler feedwater, condensate tanks, and cooling water systems. Its dual AC/DC power supply offers flexible integration into existing electrical infrastructure, and the IP67/IP68 housing withstands high-humidity and dusty environments.

Key advantages:

• Dual power input: 24VDC or 220VAC

• IP67/IP68 ingress protection

• High reliability with no moving parts

Water & Wastewater Treatment

In water treatment and sewage facilities, the MG8400 is used for level control in pump stations, sedimentation tanks, and sludge thickeners. The short fork design allows installation at any angle, and the device is unaffected by medium flow rate or turbulent conditions in mixed liquid applications.

Key advantages:

• Short fork for any-angle installation

• Unaffected by medium flow rate and turbulence

• Suitable for slurries and mixed liquids

• Insertion length from 100 mm to 3000 mm

Pulp and Paper Industry

In pulp and paper mills, the MG8400 handles level detection of fibrous slurries, paper stock, and chemical additives. The tuning fork is resistant to material buildup and hanging, ensuring consistent switching performance even with viscous or sheet-like media.

Key advantages:

• Resistant to material buildup and adhesion

• Suitable for slurries and sheet-like media

• Maintenance-free operation in continuous processes
