2280 Vibrating Fork Level Switch

Level Sensors | Vibrating Level Switch

Level Sensor Approvals: ATEX CE and IECEE

• Maintenance free
• Selectable sensitivity
• Relay or electronic output

The Type 2280 +GF+ Tuning Forks are a vibrating fork level switch suitable for level detection of liquids or granular, powdered solids. Mounted on tanks filling / emptying can be controlled using these devices just as well they can generate fail-safe alarms providing overfill- or dry run protection. The operation principle is based on the electronic circuit exciting the fork probe making it vibrate. As the medium reaches and covers the fork its vibration changes. The electronics senses the change of vibration and gives output signal after a selected delay

Features of the Signet 2280 vibrating fork level switch include:

Maintenance free vibrating principle
Independent of the liquid conductivity, dielectric constant, viscosity, pressure and temperature
Selectable sensitivity
Relay or electronic output
Temperatures up to 130 degrees
ATEX and WHG approvals
IP67, 65/68 protection

Typical Applications:

River water
Water/Glycol Solutions
Potable water
Demineralized water
Cooling Water
Chemicals
