Liquid level pressure sensor high accuracy 4-20mA for water Tanks and Deep Well Pump
Liquid level pressure transmitter sensor PT-928 adopts the diffused silicon pressure sensor core of an internationally renowned company. It converts the measured liquid depth into 4~20mA through a highly reliable amplification circuit and precise digital temperature compensation and non-linear correction technology. , 0~10VDC analog signal and IIC, RS485 and other standard digital signals. It has a wide measuring range and a variety of output signals. Good stability over a wide temperature range. Fully sealed 304 stainless steel isolated small structure, protection grade IP68. Users can measure the height of various liquids conveniently, quickly and accurately. The ultra-high cost performance can be widely used in water conservancy monitoring, underwater environmental work, tap water pipeline systems, underground water pipeline pressure measurement, industrial process pressure measurement and other fields. Can be customized and OEM manufactured according to needs.

Selection tips:
1. When selecting, please note that the medium to be measured must be compatible with the part of the product that is in contact with the medium. At the same time, the type of the medium to be measured must be noted.
Specific gravity (default is water 1g/³ T=4℃).
2. Voltage input and output have various ranges, which need to be specified in the order.
3. IIC output type has no polarity protection. The installation and use process must be confirmed before powering on. The wire length is less than 3 meters.
4. The cable must not be bent vertically during installation, but must be bent in an arc to avoid clogging the air guide holes and affecting accuracy.
5. When measuring flowing liquid, you can insert a hard tube of about φ50 into the liquid, and open a number of small holes at different heights in the opposite direction of the water flow in the tube to avoid the impact of liquid flow on the pressure.
6. When the product is installed in an area with frequent thunderstorms, it is recommended that the user install a lightning protection device.
