A broad list of sensor manufacturers, dealers, supplier, distributors, wholesalers, stockists and services can be found here to meet your purchasing needs.

A sensor is a device that detects a specific environmental input such as light, moisture, motion, heat and pressure. The output is then converted to human-readable display or transmitted electronically over the network for further processing.

Sensors are instruments often applied in detecting any modifications or changes in status and quantity in a system. They quickly provide an output response to either an optical or electrical signal. Blood pressure, speed, temperature and humidity are some of the physical factors that sensors can discover, convert and measure. The mercury-in-glass thermometer is a classic sensor example. The liquid substance expands and contracts to show a temperature measurement on its glass tube.

Classification of Sensors

• Electrical sensors rely on electrical current to produce a proportional signal or output to identify underlying changes. Galvanometer, current sensor, voltage detector and planar hall sensor are under this classification.
• Optical sensors count on light in order to provide information or electric current for a user to utilize. Devices under this classification are phototransistors, flame detectors, charge-coupled device, electro-optical sensor and colorimeter.
• Chemical sensors are used industrially and medically. They are able to find out any changes in a body or in a place by gathering any forms of liquid and air in the area.
• Acoustic sensors depend on the produced sound and vibration when detecting any changes. The lace sensor, geophone and hydrophone are acoustic sensor types.
• Thermal sensors are designed to analyze changes based on heat and temperature. Thermocouple, pyrometer, bolometer and infrared thermometer are some of the equipment under this category.

Good sensors are only focused on the measured quantity only and do not influence the gathered measurement. They also have the following characteristics: measurement limit, calibration, resolution, environmental condition, accuracy and cost.

The Green Book has a broad range of sensor related products, services and companies, specifically arranged to provide clients and customers their procurement needs. The site offers a comprehensive list of trusted contractors, wholesalers, suppliers and manufacturers whose information can be used for any business enquiries.
