| OPERATION | |
|
The Model LD100 is a gas leak detector to be used for monitoring atmospheric content of hazardous gases, specifically chlorine, sulfur dioxide, or ammonia. The detector has selectable alarm points to activate a contact closure output for control of external devices such as automatic actuators, alarm lights, sounding devices, or remote signals sent via SCADA or in-plant computer. An analog output is available for remote monitoring or indication of the specific gas content in PPM. The sensor is temperature compensated to minimize thermal effects. The compact enclosure includes power light, alarm light, pushbutton acknowledge switch, sensor, temperature compensation and customer terminals. The detector is designed to be mounted at the point of concern. |

NOTE
|
| 1. The LD100 Chlorine sensor may exhibit a response to
certain gases in a sample other than the target gas. Possible reaction to
other gases is shown below. The table shows the typical response to be expected
from a sensor when exposed to a given test gas concentration. For details
of other possible cross-interfering gases, contact the factory. |
