Product Specification
| Operating Temperature | -40℃~+125℃ | Description | Gas Sensor RoHS |
| Mfr. Part # | TC1326-AS | Model Number | TC1326-AS |
The SGX Sensortech TC-1326 is a low-power, robust MEMS thermal conductivity sensor specifically designed for detecting hydrogen due to its high thermal conductivity. It is optimized for hydrogen and methane detection (0-100% volume in air) but can also detect other gases with a sufficient thermal conductivity difference compared to air. Its small size, high resistance to mechanical shocks, and low orientation effect make it ideal for battery-operated applications. The sensor operates on the principle of differential heat loss between a sensing element exposed to the atmosphere and a sealed reference element.
| Specification | Details |
|---|---|
| Models | TC-1326-A, TC-1326-AS |
| Sensing Principle | Thermal conductivity |
| Optimized for | Hydrogen and Methane (0-100% volume in air) |
| Detects | Gases with sufficient thermal conductivity difference compared to reference (air) |
| Power Consumption | Low power, suitable for battery operation (average < 15 mW with 10% duty cycle, 1s periodicity) |
| Size | 5x5x2 mm (dual package) |
| Resistance to Shocks | High |
| Orientation Effect | Low |
| Operating Mode | Continuous or cycle mode |
| Recommended Bridge Supply Voltage | 2.9 to 3.1V (polarity reversible) |
| Sensor Current (at 3.0 0.1V) | 36 to 42 mA |
| Minimum Sensitivity | 5 mV/% hydrogen (measured at 3.0 0.1V using 1% hydrogen) |
| Zero Offset Range in Air (at 3.0 0.1V) | 20 mV max |
| Response Time (t90) | Dependent on mounting type |
| Maximum Input Voltage (pins B & G) | 1.55 V |
| Operating & Storage Temperature | -40 to +125 C |
| Humidity (non-condensing) | 0 to 95%RH |
| Heater Voltage Rating | Exceeding maximum rating will destroy MEMS heaters |
| Poisoning Resistance | No catalytic processes, resistant to poisons like organic silicones |
| Oxygen Requirement | Does not require oxygen to function |
| Humidity/Pressure Effect | Can affect sensor zero, potentially compensable with extra sensors |
| Mounting Recommendation | Vertical mounting to avoid water accumulation; detector and reference mounted close together |
| Hazardous Area Installation Note | Not assessed as a safety device |
Note: The TC-1326-A and TC-1326-AS are purely ohmic resistors and are not polarized.
