Galvanic Oxygen Transducer
Part #: TSD301

The TSD301 Galvanic Oxygen Transducer is used to measure ambient or flow stream oxygen levels in a range of 0-100%. The TSD301 has a response time of approximately 12 seconds for measuring changes in oxygen levels for input gases at a flow rate of 0.2-2.0 L/min with approximately 2% linearity.

The TSD301 transducer incorporates a detachable sensor (RX301). The sensor operates via the electrochemical (galvanic) principle and is replaceable; the sensor has an expected lifetime of approximately five years in constant exposure to atmosphere.

Interfaces with DA100C.
