Productoverview:

ZW-YCK series Anti-corrosion type fork liquid level switch Almost all used in liquid medium, such as explosive and non explosive liquid, corrosive liquid (acid and alkali) of high viscosity liquid; it is not a bubble, eddy current, gas effect.At the same time can be used to measure light free flowing solid powder or granule. Tuning fork switch can be measured a variety of material / liquid, with high and low fault safety limit switch or air overflow protection, pump control, display tube with and without fluid etc..

Two, structure principle:

ZW-YCK series of <strong> anti-corrosion type fork liquid level switch</strong> is a new type of liquid level switch. The principle is through the installation of the fork on the base of the piezoelectric tuning fork vibration in resonance frequency. When the tuning fork and the medium contact, the frequency and amplitude of the tuning fork will change, these changes are detected by the intelligent circuit, and converts it into a signal switch. Tuning fork switch is also called "electric float", and because of where the use of the float switch can structure, turbulence, agitation, bubble, vibration and other reasons can not use the float switch use electric float". No moving parts, so there is no need of maintenance and adjustment, is a replacement of the float switch upgrade. On the level of the upper and lower limit alarm and control.

Three, application:

ZW-YCK series of <strong> anti-corrosion type fork liquid level switch</strong> in industrial applications in higher utilization rates, wider range. Anti-corrosion type fork liquid level switch can be measured in addition to covering the general situation, because of its strong corrosion resistance, but also can measure the oxalic acid, hydrofluoric acid, hydrochloric acid, hydrogen peroxide, nitro fluoroantimonic sulfonic acid and other strong corrosive chemical medium, has been widely used in metallurgy, building materials, chemical industry, the level of light industry etc. industry control.

Four, main features:

1, with intelligent circuit level, level switch, used in almost all of the liquid - solid particles of light;

2, a variety of output form -- 2 wire AC, 2 wire DC;

3, high frequency excitation, strong anti-interference;

4, simple installation and maintenance free;

5, operation and conductivity of liquid, high dielectric constant, viscosity, pressure, temperature.

Five, technical parameters:

1, the power supply voltage: DC24V or AC220V;

2, the working temperature of -40 to 150 DEG C: fork;

3, the ambient temperature to 70 DEG C: -20;

4, working pressure: 2MPa;

5, medium density: 0.7g/cm3;

6, output: relay output (AC220V/5A, DC, 28V/10A);

7, the output delay: 1 ~ 50 seconds adjustable;

8, power consumption: 0.5W;

9, the high and low alarm: the scene is set to HLFS (high alarm mode) or LLFS (low alarm mode);

10, electrical interface: 3/4 "NPT; M20 * 1.5

11, process connection: 1 "NPT screw (standard, optional BSPT); flanges (optional);

12, shell protection: IP65; 13, D II CT4 explosion proof mark: Ex.

Sixth, installation instructions:

Usually the side mounted (mounted on the side wall) installation and silo wall of material level detection on the lower limit position of the silo body; when the inconvenience of side hole can be used when the top loading (installed in the warehouse at the top) installed position should be selected to avoid the impact of the position of material feeding; no material can be installed and run on pump to prevent pipeline.

Seventh, note:

1, install the sensor when inserted into the tank, with a wrench at the upper part of the square of six sensor screw can be tightened, not moving case wring their hands, because in the process of tightening will cause the shell and the probe rod rotates between. The connecting cable electronic unit and sensor in the factory inside the casing is connected, screwing the shell will connect the internal tensile cable.

2, pay attention to installation of the fork body do not have a strong impact, so as to avoid damage to the piezoelectric crystal.

3, the instrument sensor should try to avoid the impact of the material, the level of installation, the fork body two parallel fork plate should be perpendicular to the ground (the way fork onto or down direction markers), to ensure that the material can easily flow out from between the forks.

Eight, the selection of encoding:

Nine, design selection and ordering information:

1, the level control device specifications;

2, measuring range;

3, working pressure and temperature;

4, material control device;

5, the special requirements of negotiation;

6, whether the liquid level device supporting the supply vessel flange, bolts, nuts, washers and valve sealing parts, so that the correct selection.
