Product Description

Product Description

 

Overview
In terms of capacitive sensing principle, QYB240 transforms various liquid altitude into standard current signal, passing to control cabin or computer for secondary instrument,alarm or 

automatic control. QYB240 applys to high-temperature, high-pressure,high-corrosion, easy crystallized, easy plugged  me- dium,therefore,it is widely used in drainage, acid and alkali s-

oution and boiler. There is no movable or flexible  compone- 

nts in the transmitter,as a result, it also has high shock resis- tance.The product accords with GB3836.4-2000 and  GB363

8.1-2000.

 

 

 

Main Features

a. Simple structure without movable or flexible components

b. Several output signals, convenient for different systems

c. Suitable for high-temperature, high pressure container, and the value would not influenced by temperature, pressure, specific gravity and shape of container

d. Widely used in acid and alkali solution with high-corrosion

e.Perfect protection for overflowing, over-pressure, current-limiting

Installation and test

This product has been tested before delivery, please adjust as follows if need:
A: Use the Intelligent Circuit Method:
Set Zero: When level is the lowest, press "Z" and "S" at the same time for 8s, then loosen them, and then press "Z", output current becomes 4mA automatically.
Set Full Scale: Whenlevel is the highest, press "Z" and "S" at the same time for 8s,then loosen them, and then press "S", output current becomes 20mA automatically.
B: Use the Analog Circuit Method:
When the level is the lowest, rotary "Z" slowly with screwdriver, and view the ampere meter data to close to 4mA.When the level is the highest, rotary "S" slowly with screwdriver, and view the ampere meter data to close to 20mA.Repeat above actions for 2-3 times, until zero and full scale recover to exact 4mA and 20mA, and then tightening the cover of transmitter.
