4.1. Components

[Figure 2. GTD-1000Tx(M) Components]
NO NAME
1 Housing Body Protects PCB Board built in Sensor and Housing from external environmental change and shock.
It is assembled with detector housing body and protects PCB Board built in Sensor and Housing from
2 Housing Cover
external environmental change and shock
It is a site that detects actual gas leak. It converts the amount of gas leak into electrical signal and
3 Sensor
transmits to the Main PCB.
It must be grounded to inside of detector for protection from external noise or strong electric field.
4 Internal Ground
- Use a conductor that is 4 mm or longer when coupling ground line.
It must be grounded to outside of detector for protection from external noise or strong electric field.
5 External Earth Ground
- Use a conductor that is 4 mm or longer when coupling ground line.
It is supplied for inlet of power supply and measurement output signal for the detector during
6 Conduit Connection
installation. For cable inlet, PF or NPT 1/2", 3/4" are prepared.
Amplifies fine outputs generated from Sensor Element to transmit a converted output in 4~20 mA
7 Main PCB
DC standard. It sends data to display part.
8 Mount Hole Hole to fix the gas detector on external wall or other installation sites.
