TGS3830-A00 Freon Gas Sensor MOS Semiconductor Refrigerant Metal Packaging
Features
1. High sensitivity and fast response to R134a; suitable for portable refrigerant leak detectors.
2. Lower power consumption compared to traditional Freon sensors.
3. Compact structure with a metal housing and a dust-proof, breathable mesh.
4. Output method: Sensor resistance varies with refrigerant concentration; voltage signals are acquired using a load resistor.
