Mobrey M-Switch Float Operated Liquid Level Switch

Manufactured in 316 stainless steel throughout, the M-Switch small float level switch is available for side mounting with either a flange or 50mm/2" thread.
Comprising a small float on the wet side and a body containing a high current micro-switch on the dry side, the Mobrey M-Switch small float level switch will reliably detect liquid level to give a voltage free contact operation for alarm signalling or as part of a pump control system.

Features

• Tough industrial build quality
• 316 stainless steel contruction
• Flanged or threaded mounting
• Small in-tank dimensions

Applications

• Low level alarms in lubricating oils and fuels
• Pump control duty in header tanks
• High and low alarms in condensate tanks
• Level and pump control in storage tanks

Benefits

• Simple and proven design
• Operates in most liquids
• Glandless for maximum safety and minimum maintenance
• European Directive compliance
• ATEX EExd flameproof model

 

Vertical Float Level Switches

The vertical float level switch from Mobrey carries a stainless steel sheathed permanent magnet which rises and falls in the glandless pressure tube with changing liquid level.
Switching is achieved with the unique Mobrey "3-magnet" system, giving snap-action "latch-on" switching. A switch mechanism is mounted inside the enclosure adjacent to the pressure tube. Vertical movement of the float magnet in the pressure tube simultaneously actuates the secondary and tertiary magnets in the switch mechanism to operate the contacts.
The "3-magnet" system enables the float magnet to pass on and actuate switch mechanisms at other levels. Switch mechanisms already actuated cannot re-set until the return of the primary magnet actuates the magnet system once again.

Features

• Up to 4 switch points available
• Flanged or chamber mounted
• Weatherproof to IP66/67
• Approved by many leading authorities
• Hazardous area models

Applications

• Alarm & shutdown duties
• Sump level control
• High pressures/low S.G.
• Large switching differential for pump control

Benefits

• Simple and proven design
• Operates in most liquids
• Glandless for maximum safety & minimum maintenance
• Long and trouble free operation
• Low cost of ownership

 

Mobrey Squing 2 Vibrating Fork Point Level Switch

The Squing 2 is a vibrating fork point liquid level switch designed using the principle of a tuning fork. By using piezo-crystals the Squing 2 fork is forced to resonate constantly at its natural frequency.
When the Squing 2 vibrating fork switch is installed as a high alarm, a rising liquid will come into contact with the forks and dampen them, changing their natural resonant frequency; From this the electronics make the output of Squing 2 change. Or, when installing the Squing 2 as a low alarm the fork is normally submerged; as your liquid lowers past the fork there is a change in their frequency and again the electronics make the output change.
Using short fork technology pioneered by Mobrey and many years of application experience, the Squing 2 vibrating fork point liquid level switch is designed for use in virtually all applications.
