YZLB type hydrostatic pressure liquid level transmitter

1, overview

Pressure type liquid level transmitter of the YZLB, selection of diffusion silicon pressure sensor for sensing element, through the feelings of the liquid pressure, obtains the relative height of the liquid level and converted into 4 ~ 20mA standard current signal output and transmitted to a secondary instrument, automatic control of industrial process.

The transmitter directly into the measured liquid in use, simple to install, widely used in water treatment plant, deep well, reservoir, oceans, rivers, oil tank, coal washing plant and other, used for measuring the height of the liquid, and a variety of opening level of liquid in the tank. YZLB type liquid level transmitter, a common type and intrinsically safe type two.

2, the main technical parameters:

Applicable medium: water, oil, paste, etc.;

Amount range: 0-170 m;

Precision: 0.25%, 0.5%, 0.1% (including linear, hysteresis, repeatability and three errors);

Over load: Double rated pressure;

Power supply voltage: DC24V;

Temperature: -40~125 (-20~+80);

Temperature compensation: 0~70.

3, installation and use of attention:

When the transmitter input liquid, a cable, slowly put in, not to be thrown down, so as not to damage the diaphragm.

When the measurement field of the environment temperature is below 0, the transmitter probe is removed from the measured liquid should be within the transmitter, the presence of liquid discharge clean, so as to avoid damage to the diaphragm.

Gently, avoid strong shock and vibration.

When the bottom of the measured liquid sediment, impurities, etc., should make the probe from the liquid bottom surface has a certain distance, so as to avoid the pressure inlet, affecting the measurement accuracy.

When there is turbulence, the probe should set straight to current tube, so that the output display stability.

Do not remove the probe cable, so as not to cause ventilation.
