YZLB type hydrostatic pressure liquid level
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.

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
