NAME
DESCRIPTIONS
1
Housing Body
Protects PCB Board built in Sensor and Housing from external environmental change and shock.
2
Housing Cover
It is assembled with detector housing body and protects PCB Board built in Sensor and Housing from
external environmental change and shock
3
Sensor
It is a site that detects actual gas leak. It converts the amount of gas leak into electrical signal and
transmits to the Main PCB.
4
Internal Ground
It must be grounded to inside of detector for protection from external noise or strong electric field.
- Use a conductor that is 4 mm or longer when coupling ground line.
5
External Earth Ground
It must be grounded to outside of detector for protection from external noise or strong electric field.
- Use a conductor that is 4 mm or longer when coupling ground line.
6
Conduit Connection
It is supplied for inlet of power supply and measurement output signal for the detector during
installation. For cable inlet, PF or NPT 1/2", 3/4" are prepared.
7
Main PCB
Amplifies fine outputs generated from Sensor Element to transmit a converted output in 4~20 mA
DC standard. It sends data to display part.
8
Mount Hole
Hole to fix the gas detector on external wall or other installation sites.
