Detector Accessories

 Detector Controller

The detector controller is used to supply power and process data for the gas detector. It is based on two-wire and three-wire systems.

Product model: GC-1010-AA/AE, GC-1010-CA, and GC-1020-AA/AE.

Note: The system consists of a detector and a controller. The detector is responsible for sensing toxic and harmful gas in the environment, and sending these signals to the controller or industrial computer in the safety zone through (4~20)mA output.

Explosion-proof wiring box

The explosion-proof box is used for all kinds of electrical connection industrial site with explosion proof requirement. The box is also corrosion prevented and easy to use.

TECHNICAL   DATA
Explosion   proof	Exd   II B T6, Exd II C T6
Protection class	IP65/   IP66
Rated   current	10/20/32/63/100A
Electrical   interface	G1/2,   G3/4, G1

RC-1000

Our RC-1000 overcomes limitations from traditional potentiometer, magnetic bar and one-way infrared remote control. It can be used to remotely acquire data and set parameters. With the ability to restore setting parameters, one RC-100 can be used for parameter setting and calibration for several detectors.

TECHNICAL DATA
LCD	128*128 STN LCD
Number of button	8
Battery	Two AAA batteries
Explosion-proof type	Intrinsically safe Exia IIC T4
Power consumption	<100mW
Operating humidity	(10-95)%   RH (non-condensing)
Cone angle of infrared receiver	50°
Cone angle of infrared emitter	50°
Dimension	127.7mm×48mm×26mm (H × W × T)

SG-100

SG-100 can be integratively installed on GT detector to give audible alarms and emits red flash light when gas concentration detected exceeds. The locknut design ensures alarm can be observed at any direction. It can be used in combination with all other GT series detectors except two-wire ones.

TECHNICAL   DATA
Operating   voltage	(15~30)   V DC
Operating   current	<30mA
Alarm   sound	>85dB
Operating   temperature	(-40~70)℃
Alarm   frequency	0.3Hz/3Hz
