Sensor - Wikipedia

A chemical sensor is a self-contained analytical device that can provide information about the chemical composition of its environment, that is, a liquid or a gas phase. The information is provided in the form of a measurable physical signal that is correlated with the concentration of a certain chemical species (termed as analyte).

How does an NDIR CO2 Sensor Work? |

These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module. The highly reflective coating ensured that the CO2 molecules inside the gas sample chamber would absorb the same amount of light as traditional straight-path design.

Alarm FAQs - ADT Security New Zealand

The expander module failure signal indicates that an expansion module/s is not correctly communicating to the main alarm panel. A technical inspection generally is required to identify & rectify the cause of the fault. Until returned to normal service, it can be expected that all inputs (sensors)/ relays (controllers) attached to this expander module will no longer be able to operate as ...

Operating principle ‐Electrochemical-type gas sensor

The oxidation potential of CO gas (as expressed in Equation 1) is lower than the oxidation potential of the electrode(2H+ + 2e-⇔ H 2), oxidation of CO has less noble potential than deoxidization. Since this reaction occurs easily, no external energy is needed to stimulate the sensor’s chemical reaction, unlike with three-electrode type sensors. As a result, this two-electrode type ...

Process Temperature Monitoring | Luna

Temperature mapping with high-definition temperature sensors yields more complete thermal data. A single fiber generates a continuous temperature mapping, with individual sensing locations spaced from 1 cm to less than 1 mm along the fiber or temperature probe, virtually guaranteeing that hot spots are not missed. Data is available in real-time for monitoring and feedback control. Example ...

What is a Sensor? Different Types of Sensors, Applications

2021-04-02· The definition of the Sensor can be better understood if we take an example in to consideration. The simplest example of a sensor is an LDR or a Light Dependent Resistor. It is a device, whose resistance varies according to intensity of light it is subjected to. When the light falling on an LDR is more, its resistance becomes very less and when the light is less, well, the resistance of the ...

Car Park Ventilation System Design - Fan Quantities - Fantech

CO sensors will be more effective if placed in areas where CO levels are likely to be high. Eg. Placing a CO sensor in front of a fresh air intake is not likely to be effective. If jet fans are placed in each laneway of a car park and the recommended low speed jetfan spacings are followed, the above guidelines can be achieved by using one CO sensor per jet fan and providing additional CO ...
