Small Water Level Sensor and Pressure Sensor Application Reference

Silver Automation Instruments provide cheap cost water level sensor and pressure sensor, not only the price is low, but also the quality is stable. And here is an application which customer wants low cost water pressure sensor and low water level sensor, see below how we choose cheap and correct type sensors for their applications.

Inquiry:

Hope you are well. We have re-evaluated our choices for our desired sensors. The needed items are as follows, I need all the sensors to have displays included please.

Description

a. Pressure sensor, M12*1.5 nipple insert, water pressure measurement, 0-10 bar, The operating temperature max is 100 degrees Celsius , The pressure sensors should be installed in the same manner as the SH 308 Series Diffusive Silicon Pressure Transmitter and be able to function in water.

b. Pressure sensor, M12*1.5 nipple insert, water pressure measurement, 0-0.4 bar, The operating temperature max is 100 degrees Celsius, The pressure sensors should be installed in the same manner as the SH 308 Series Diffusive Silicon Pressure Transmitter and be able to function in water.

c. Probe level sensor for use in water application, only 350mm deep, level sensor my concern is that the level of water that is going to be measured is only. The level of the water is only 350mm deep and we require fine measurement to be accurate on that small level.

1.       Max 320 mm          =         18mA.

2.       Mid  220mm          =          15mA.

3.       Low  150mm          =          10mA.

4.       Low Low100 mm  =          8mA.

5.       Zero  0mm              =         4mA

Below is the pictures show how will they install and where the water level meter install

Wish SILVER AUTOMATION INSTRUMENTS comments on our water level and water pressure sensor applications, and choose correct types pressure and level instruments.

Hi, after seeing your request, we have 2 problems need to fix:

First, we talk about our water level transmitter linear relation.

Your request set is as below:

1.       Maxlevel320 mm          =         18mA.

2.       Mid level 220mm          =          15mA.

3.       Low level150mm          =          10mA.

4.       Low Low level100 mm  =          8mA.

5.       Zero level 0mm              =         4mA


Obviously, our SHLT02 level meter cannot meet your setting demand, the mA output should be in linear relationship with the level range, the correct setting should be as below

1.       Maxlevel320 mm          =         18mA.

2.       Mid level  220mm          =          12.375mA..

3.       Low level 150mm          =         8.4375mA.

4.       Low Low level  100 mm  =          5.625mA.

5.       Zero level 0mm              =         4mA


Secondly, we talk about your extremely small water level

Our normal SHLT02 cable type level meter cannot handle so small level range, you should use our advanced Ceramic core Level transmitters, the appearance is similar like SHLT02, but the inside technology is better and more accurate and can handle your small level range and realize fine level measurement as your desired.
