NAME
DESCRIPTIONS
1
Housing Body
Protects PCB Board built in Sensor and Housing from external environmental change and shock.
2
Housing Cover
Top surface is built with circular glass to enable monitoring of measurement displayed on LCD.
3
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.
4
Display PCB
Displays data (measurement) sent from Main/ Terminal (Transmitter) PCB on LCD and displays power
status with a power lamp.
5
Power/Signal Terminal
CN8 consists DC18V~31 24 V power supply and DC 4~20 mA standard output connection terminal
(VISO, +24V, mA, GND, ETH).
6
Sensor Terminal
CN4 is Sensor Connection Terminal.
7
Power LED
It is lamp that turns on when power is supplied.
8
Function Key
It is used to enter function setting mode from gas measuring mode by contacting magnet-bar for 2
sec or longer. It is also used to save changed data from function setting mode.
