2214003 CS 21 Fixed Gas Transmitter, Freon 717 (NH3), 0(30) - 10,000 ppm by GfG
The CS 21 transmitter uses the proven chemosorption detection principle for detection of toxic gases, vapors and combustibles. The rapid response of the transmitter provides opportunity to take counter measures and thereby limit damages. The long life of the sensors makes the CS 21 a low-cost solution for your detection needs. A transmitter can be continuously operated for more than 5 years.
Wall mount installation is straightforward. The distance between transmitter and controller can be greater than 500 m. A rugged aluminum casing protects the sensor and electronics from splashes of water and dirt. The transmitter must not be operated in EX-areas. For measurement of combustible gases in the LEL range the gas needs to be sampled by pump. In this case the EX-protection needs to be guaranteed with suitable external components (e.g.flame-protection).
- High sensitivity to a broad range of refrigerants
- Long sensor life
- Fast response
