Industrial metal detectors indicate the presence of metal in nonconductive materials such as textiles, rubber, oils or liquids, plastics, powders, wood products and concrete.
Motion detectors are devices that contain either a physical mechanism or an electronic sensor that detects motion within a specific field of view. Common motion detectors include passive infrared (PIR) and active ultrasonic and microwave.

RF Power Detector ICs

(8 companies)
RF Power Detector IC's. are chips that detect the presence and strength of an RF signals and provide a corresponding output.

Lighting Fixtures

(1,655 companies)
Lighting fixtures produce artificial light in industrial areas or workspaces.

Focal Plane Arrays

(21 companies)
Focal plane arrays (FPA) are detectors consisting of a linear or two-dimensional matrix of individual detector elements, typically used at the focus of an imaging system.

Gas Sensors

(552 companies)
Gas sensors interact with a gas to initiate the measurement of its concentration. The sensor then provides output to an instrument to display the measurements.

Gas Instruments

Underground locating equipment locates buried utility lines and infrastructure. This includes marker systems, fault detectors, ground penetrating radar, metal detectors, RF equipment, acoustic detectors, and beacon (sonde) devices.

Security System Services

(451 companies)
Security system services install, maintain, and monitor security equipment such as CCTV systems, security cameras, building monitors, entry alarms, metal detectors, and movement and occupancy sensors.

Photosensor Modules

(76 companies)
Photosensor modules are compact light detectors with built-in power supplies. They use photomultiplier tubes, avalanche photodiodes, PN photodiodes, or PIN photodiodes.

Fire Protection Services

(272 companies)
Fire protection services install, maintain and monitor safety equipment such as flame and smoke detectors, sprinkler systems, fire alarms and annunciators.
Dissolved CO2 instruments are analytical devices that measure the amount of carbon dioxide (CO2) dissolved in a liquid sample such as water. They typically include a submerged probe that is covered by a thin organic membrane.

Leak Testing Equipment
