Product Overview

Fork level switch uses the signal of electronic circuit to stimulate the crystal in the fork body, so that the fork body of

tuning fork vibrates at a fixed frequency, when the fork body is completely submerged by the measured material, the

vibration frequency of the fork body changes, and the electronic circuit of the instrument automatically detects this change

and converts it into a switching signal to be output by the relay, which is used for on-site alarm or remote control, and the

instrument returns to its normal working condition when the material is out of the fork body, and continues to detect the

change of the level. Tuning fork level switches can monitor, control and alarm the high and low levels of material tanks and

are suitable for all kinds of liquids, powders and granular solids.

Power supply voltage: DC24V or AC220V.

Operating temperature -40~150°C.

Ambient temperature: -20~70°C.

Operating pressure: ≤ 2.0MPa.

Medium density: ≥0.7g/cm³.

Output mode: relay output

(AC220V/5A,DC28V/10A).

Power consumption: 0.5W.

High and low level alarms: on-site settable

to HLFS (high level alarm mode) or LLFS

(low level alarm mode)
