توضیحات
The Mobrey Squing 2 is designed using the principle of a tuning fork. A piezo-electric crystal oscillates the forks at their natural frequency. Changes to this frequency are continuously monitored. The frequency of the vibrating fork sensor changes depending on the medium in which it is immersed. The denser the liquid, the lower the frequency. When used as a low level alarm, the liquid in the tank or pipe drains down past the fork, causing a change of natural frequency that is detected by the electronics and switches the output state. When the Squing 2 is used as a high level alarm, the liquid rises in the tank or pipe, making contact with the fork which then causes the output state to switch.
Features:
Features:
Virtually unaffected by turbulence, foam, vibration, solids content, coating liquids, or liquid properties
The Squing 2 is designed for operation in process temperatures from –40 to 302 °F (–40 to 150 °C)
A ‘heartbeat’ LED indicates its operating state. The LED also flashes when the switch output is ‘off’ and is constantly lit when ‘on’
Adjustable switching delay prevents false switching in turbulent or splashing applications
‘Fast Drip’ fork design gives quicker response time, especially with viscous liquids
Rapid wet-to-dry and dry-to-wet time setting for highly responsive switching
Fork shape is optimized for hand polishing to meet hygienic requirements
No moving parts or crevices for virtually no maintenance
