| The S4100T Intelligent Sensor is a highly reliable, self-contained, microprocessor-controlled hydrogen sulphide transmitter with integral 3 digit readout. It is designed to measure and display concentrations of H2S in the 0-20 ppm, 0-50 ppm or 0-100 ppm range, but will continue to display concentrations up to 120% FSD. The sensing element may be incorporated in the transmitter housing or remotely mounted at distances of 600 meters. The sensor employs thin film metal oxide semiconductor (TFMOS) technology as the measuring principle. |

SIMTRONICS “TT63ES” detector is a semi-conductor sensor type with a very low cross sensitivity to other gas.
The basic principle is the resistance variation of a tin oxide semi-conductor. The inflammable gas reacts with the oxygen absorbed at the surface of the semi-conductor, and causes the electric resistance to decrease. The nature of the semi-conductor, its doping and its service temperature contribute to better detectivity of certain gases.
When other semiconductor on the market need to smell gas every week to avoid the sensor to fall asleep, the SIMTRONICSsemiconductor sensor only needs a six-month or one year calibration test.
Modern electronics provides high performance for humidity and temperature rate compensation and long term stability. The circuits ensuring the supply to the sensor, the amplifier and the interface are grouped in the flameproof enclosure onto which the detection probe is secured. |

The Model IR2100 Infrared Point Detector is a microprocessor-based hydrocarbon gas detector that continuously monitors combustible gases and vapors within the lower explosive limit (LEL) and provides alarm indication.
All electronics are contained within an explosion-proof housing so that the IR2100's detector information can be processed locally. The IR2100 operates with a 4-20mA signal, which is proportional to 0 to 100% LEL gas concentration at the detector. RS-485 serial communications are MODBUS RTU compatible. The RS-485 output provides status, alarm, fault and other information for operation, troubleshooting or programming the unit. |

The sensing element of Figaro gas sensors is a tin dioxide (SnO2) semiconductor which has low conductivity in clean air. In the presence of a detectable gas, the sensor's conductivity increases depending on the gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration.
The TGS 832 has high sensitivity to R-134a, the most promising alternative to R-12, commonly used in air conditioning systems and refrigerators. R-12 and R-22 are also detectable by TGS 832. With its good long term stability, TGS 832 is an excellent, low-cost sensor for CFC detection. |

When used with gas and smoke sensors (refer to page 96), GRM
continuously monitors explosive gases, vapours and/or smoke and
generates alarms. The GRM electronic gas and smoke detector is installed in boiler rooms and basements, storage, office and living rooms as well as
public facilities or industrial buildings for increased safety (building
technology). The evaluation unit is designed for either wall mounting
or control panel mounting by means of a mounting frame (refer
to page 74). GRM has an alarm threshold and is fitted with a relay
contact. When the threshold value is exceeded, the unit generates an
alarm signal. The red "Alarm" LED lights up and the alarm relay
switches. An additional integrated buzzer provides an audible alarm.
This audible alarm can be muted with the re-set button. If the condition
which caused an alarm is cleared, the visual alarm can then also
be re-set by once again pressing the re-set button. Only then can
the alarm be muted with the re-set button. However, if the gas concentration level is still above the alarm threshold level, muting of the alarm is not possible. |

TGS 3870 is Figaro's new metal oxide semiconductor gas sensor for the detection of both methane and carbon monoxide. Using a micro-bead gas sensing structure, both methane and carbon monoxide can be detected with a single sensor element by periodic application of two different heater voltages (high and low). Miniaturization of the gas sensing bead results in a heater power consumption of only 38mW (average).
TGS 3870 has low sensitivity to alcohol vapors (a typical interference gas in the residential environment) and has high durability, making the sensor ideal for consumer market gas alarms. |
