1, Introduction
TP-2 normal temperature carbon monoxide (CO) sensor is made of SnO2 multi-crystalloid appending propriety extender. It has tiny pearl structure, conductance surge response, wonderful select character and good environment accommodate capability. Its operating circuit is simple. Intrinsically safety. CO detectors which is made from TP-2 can meet UL2034 standards and do not need temperature and humidity compensation.
2, Operating Condition
1) Operating voltage: 3.5V~6.5V
2) Operating circuit: see Fig 1
Operating circuit The selection of RL
3)Static power dissipation: ≤15mV
4)Environment: temperature:-10°C~+50°C relative humidity≤95%
5)Time of stable values:≤15分钟
6)Cell detectable range:0~2000ppm CO
3, Sensitivity response
Conductance surge response
Fig 2 shows the response of the sensor at the normal temperature when submitted to 100ppm carbon monoxide.电导振荡
4, Application ranges
Detecting the low level of carbon monoxide
Detecting the high level of carbon monoxide or charcoal
Portable carbon monoxide detector
Automobile carbon monoxide detector
