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° |
