Industrial Organic Chemical Sensor

The sensor can be operated using a simple voltage divider. This requires two voltage supplies: the heater voltage (V H) and circuit voltage (V C). V H is applied to the heater in order to maintain a constant, elevated temperature for optimum sensing. V C is applied to allow a measurement of the output voltage (V OUT) across a load resistor (R L). Figure 4. Basic Measurement Circuit V OUT V H V ...

The VOC pin voltage can be set using R4, R5 resistor dividers from VREF on bidirectional devices. The fault performance is valid when VVOC is within the VOC Operating Voltage Range or < V. The device will respond to voltage outside of the defined valid performance region with varied results. For a 5 V bidirectional device, setting the VOC pin to V selects the minimum trip point, IFAULT ...

VOC Sensors and Monitors Volatile Organic Compounds

Both sensor types are nonselective which means they can be used for measuring a wide variety of VOCs. To achieve this they have been calibrated against isobutylene that allows them to respond to a wide range of VOCs at varying degrees of sensitivity. Each type has a calibrated measurement range against a set of VOCs. PID type VOC sensors are more resilient and can detect a wider variety of VOCs.
