1Equipment Composition

IIEquipment principle

The input type static pressure level transmitter is based on the principle that the measured liquid static pressure is proportional to the height of the liquid. It uses advanced isolation type diffusion silicon sensitive elements from abroad to convert static pressure into electrical signals. After temperature compensation and linear correction, it is converted into standard electrical signals (generally 4-20mA).

IIIApplication scope

It can be widely used in water plants, sewage treatment plants, urban water supply, high-rise water tanks, wells, geothermal wells, mines, industrial water tanks, oil tanks, hydrogeology, reservoirs, rivers, oceans and other occasions.

4equipment installation

Avoid installation in environments with mechanical vibration and strong electromagnetic interference:

1.The transmitter can be installed vertically, obliquely, or horizontally in the tank or groove, ensuring that impurities such as sediment do not bury or block the probe part of the transmitter.

2.When the medium fluctuates greatly, measures should be taken to fix the probe part of the transmitter, such as adding counterweights to the transmitter;

3.In addition to serving as a power source and signal transmission, the air guide cable also plays a crucial role in atmospheric compensation. During installation, it is important to avoid locking the cable too tightly or bending it too sharply to prevent the air guide pipe from being blocked or broken;

4 The shell is vertically installed on a bracket above or near the tank, while ensuring sun protection and breathability. The installation position is convenient for wiring and debugging.
