1 minute 10 N online derivation on pulling force, no loose, tensile, and no change in performance.

14、Durability

At room temperature, from the inlet to the 0.1 MPa water pressure, to get through 1 S, disconnect 0.5 S for a cycle, to test 300000 times without exception.

 

 

 

 

Remark

  1. Don’t disassemble when the product is found to have quality problems .
  2. For dry air sensor within the residual water should pay attention to the blowing pressure <0.3MPa and intermittent output impeller.Can not be rotated at high speed in the anhydrous state .

 

 

Connection mode:

  1. RED line for power+
  2. BLACK line for power-

YELLOW line for signal output

 

 

Installation instructions

1、When magnetic materials or to flow switch a magnetic force materials near water flow switch, its characteristics may change.

2、In order to avoid particles, sundry into the flow switch, in the inlet must install screen pack.

3、In the use of the water flow switch before please read the parameters that if there are still questions please to our factory technical personnel consultation.

4、In the process of installation and use must cooperate relays (power in 3 W below), lest because of switch power small and dry reed pipe burn out.

5、The water flow switch installation use environment to avoid strong vibration and shaking place, in order to avoid water flow switch produce false action.
