YZF-60K signal oil level gauge
First, use:
???
The oil level gauge is suitable for mounting on small and medium sized oil-immersed transformer conservator and on-load tap sidewalls conservator oil level indication can also be used for other open pressure vessel level measurement can replace Unicom Glass oil level gauge, and comes with high and low there was a switch signal output, with a secure, intuitive, reliable, long service life.
Second, the working conditions:
1, ambient temperature: -40 ℃ ~ 80 ℃
2, relative humidity: when the air temperature is 25 ℃, humidity less than 90%
3. Altitude: ≤2000m
4. Mounting position without intense vibration and strong magnetic fields
5, the oil level should be mounted vertically
6, the working voltage: 24V product comes with AC220V convert DC24V power switch
7, pressure rating: 1000V
Third, the structure and working principle:
1, the oil level gauge structure: the oil level gauge from the float rod magnet pointer table seat, etc., because of the oil level gauge table seat float to completely isolate the pointer, thus ensuring the reliability of sealing the oil level gauge.
2. How it works: When the oil inside the oil level due to temperature or other causes increased or decreased, the oil level gauge float sync with oil increased or decreased, which led pointer rotation, but low oil level.
3. Internal own position sensing device, the output when the oil level indicator rose to the highest point in the switch is closed or bottoming out signal, output short term indicator level signal when the other position.
Fourth, note:
1, the oil level gauge not subject to strong collision.
2, the oil level gauge rod can not be forced to bend or stretch deformation, can not have a strong magnetic field nearby.
3, the installation diagram seal to prevent leakage from the role, if not sealed, check the screws are tightened, or mounting plate to seal uneven contact points.
Fifth, the installation:
1, the oil level gauge with oil at 25 ℃ as the reference temperature of the oil, so the oil level should be installed and draw oil temperature measured by calculating according to the correct height.
2, the oil level gauge (standard) Maximum effective measuring range of 100mm, if other requirements, the user can demand formulation (determining the figure at R90).
3, the oil level gauge terminal wiring diagram:
4. Install the size and shape:
