The explosion-proof mechanical pig passing indicator

We confirm the ball indicator meets the following requirements of the technology.

1) It can realize the digital display of the results to check the situation at any time. It can offer the normal time display and the passing time display of the pipe-cleaning, clearly and reliably.

2) It can realize the removal with pressure. The instrument part can be removed with the maximum pressure of 12MPa on the pipe.

3) It offers the explosion-proof design. Explosion-proof level: dⅡBT4; Protection level: IP65; Corrosion level: WF1.

4) It offers the remote transmission function for the signals: it can realize the remote transmission of instant conduction of the switch signals with the passing of the pipe-cleaning.

5) Cable entry thread of the remote transmission signal: 1/2 NPT; contact capacity: 24 VDC. 3 A.

6) The automatic reset in the mechanical parts while manual reset in the instrument parts.
