PRODUCT INFORMATIONTGS2610-C00 - for the detection of LP Gas
Features:

Applications:* Quick response* Low power consumption* Long life and low cost
* Uses simple electrical circuit* Portable LP gas detectors* LP gas and vapor detection

TGS2610-C00 is a semiconductor type gas sensor which combines very
high sensitivity to LP gas with low power consumption and long life. Due tominiaturization of its sensing chip, TGS2610-C00 requires a heater current ofonly 56mA and the device is housed in a standard TO-5 package.
TGS2610-C00 possesses small size and quick gas response, making it suitablefor gas leakage checkers.
The TGS2610-C00 is able to satisfy the requirements of performance standards
such as UL1484 and EN50194.

The figure below represents typical sensitivity characteristics,
all data having been gathered at standard test conditions (seereverse side of this sheet). The Y-axis indicates sensor resistance ratio (Rs/Ro) which is defined as follows:
Rs = Sensor resistance at various concentrations
Ro = Sensor resistance in 1800ppm of iso-butane

The figure below represents the typical response pattern when
the sensor is inserted into and later removed from 1800ppm
of iso-butane.

PRODUCT INFORMATION(+)

Basic Measuring Circuit:
The sensor requires two voltage inputs:
heater voltage (VH) and circuit voltage(VC). The heater voltage (VH) is appliedto the integrated heater in order tomaintain the sensing element at a specifictemperature which is optimal for sensing.
Circuit voltage (VC) is applied to allow
measurement of voltage (VOUT) acrossa load resistor (RL) which is connected
in series with the sensor.

A common power supply circuit canbe used for both VC and VH to fulfill thesensor's electrical requirements. Thevalue of the load resistor (RL) should bechosen to optimize the alarm thresholdvalue, keeping power dissipation (PS)of the semiconductor below a limit of
15mW. Power dissipation (PS) will behighest when the value of Rs is equal
to RL on exposure to gas.
