Sensor Electronics has combined a SEC 3100 transmitter and a SEC 3000 sensor to form a new gas-detection team that is capable of detecting traces of toxic gases. It can react to dangerous gases such as dichlorosilane and tungsten hexafluoride.
The transmitter has a plug-in type of memory stick that can record the actual level of the gases and their concentrations at particular times, and other information such as service interruptions and trouble signals. The memory stick can be removed from the transmitter and plugged into a computer for downloading information for recovery and analysis.
The SEC 3100 transmitter has a height, depth and width of 5", and the cylindrical sensor made of stainless-steel has a diameter of 2" and a depth of 3". The transmitter can be placed at a distance of 1000 ft from the sensor or coupled directly. Both the sensor and transmitter can withstand temperatures ranging from -40°F to 160°F and RH varying from 0% to 99%. They can also compensate automatically for wide variations of temperature.
The transmitter displays the actual gas levels either as % LEL or as PPM. Based on the changes in gas concentrations, color-coded LEDs change their color. The device can be made to shut down lines, turn on exhaust fans and trigger alarms when the gas concentration reaches a particular level. The SEC 3100 transmitter monitors itself and the display shows the location and the problem.
