HQ2600 cable Type Liquid Level Transmitter
Application
HQ260O cable type liquid level transmitter is made of high performance diffused silicon piezoresistive pressure Force sensor as a measuring element, the liquid static pressure proportional to the depth of the liquid level.
The force is accurately measured and converted to standard (current) by a signal conditioning circuit or voltage) signal output, establish a linear pair of output signal and liquid depth to measure the depth of liquid.High precision, small size, directly into the liquid, you can measure the end of the transmitter to the liquid level of liquid height degree, easy to use. suitable for petroleum, chemical, power plant, city frequency conversion supply level measurement and control in the field of water and hydrology exploration. After long-term aging and stability screening, product performance is stable and reliable, It can be applied to the harsh environment of the open field, and can be on-site liquid bit display, zero, full migration.

Electrical connections
lnstallation Diagram (Recommended reference)
Installation in standing water (deep wells, pools, liquid tanks, etc.)
1.When measuring the level of a still fluid in an open container, place the level transmitter vertically into the bottom of the container and connect the transmitter at the opening of the container cable and junction box are fixed.
2.When the medium viscosity is large (such as sewage pool) can be installed casing or bracket, ensure that the transmitter can be put into the bottom of the container.
3.When installing in the open air, the junction box of the transmitter should be placed in a ventilated and dry place as far as possible to avoid direct exposure to strong light and rain, resulting in high temperature of the shell or water. And damage the internal circuit board.
Installation in moving water (rivers, rivers, lakes, etc.)
1.When the water level is measured in flowing water, the medium fluctuates greatly, a steel pipe can be inserted in the channel, with an inner diameter of about 50 centimeters, in the invasion. The pipe in the water is located in the opposite direction of the flow of water at different heights to open a number of holes about φ 5, So that the water into the pipe, at the outlet of the pipe and cable connection cable box fixed.
2.When the fluctuation of the channel medium and the sediment are large, it is also possible to filter the sediment and eliminate the adverse effects of dynamic pressure and waves by adding damping devices. Ensure measurement accuracy.
3.When the product is installed in lightning prone areas, the "lightning protection" should be marked when ordering. At the same time, it is recommended that users install lightning protection devices on site, and ensure that the product and electricity Reliable grounding of the source can reduce the probability of lightning damage to the transmitter.
