HPLC Detectors

(49 companies)
High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated.

Helium Neon Lasers

(36 companies)
Helium neon (HeNe) lasers have an emission that is determined by neon atoms by virtue of a resonant transfer of excitation of helium. They operate continuously in the red, infrared and far-infrared regions and emit highly monochromatic radiation.
Condition monitors and fault detectors find faults in mechanical, electrical, optical or other systems before a system failure condition occurs. An example of a fault in an electrical system is an arching circuit breaker. An example of a fault in a mechanical system is a failed roller bearing. Both mechanical and electrical faults produce characteristic sounds, which can be detected using air or structure borne acoustic detection techniques.

Flow Meters

(1,652 companies)
Flow meters (flowmeters) and flow sensors are devices used for measuring the flow rate or quantity of a moving fluid or gas.
Helium cadmium (HeCd) lasers are relatively economical, continuous-wave sources for violet (442 nm) and ultraviolet (325 nm) output. They are used for 3-D stereolithography applications, as well as for exposing holographs.

Heat Detectors

(113 companies)
Heat detectors are fire detection devices that sense heat produced by combustion. Heat detectors can trigger an alarm when they detect rapid temperature rise or reach a preset temperature.
Handheld computers are portable devices including notebook and subnotebook computers, palmtops, and PDAs.

Flame Detectors

(178 companies)
Flame detectors monitor and analyze incoming radiation at selected wavelengths.
Industrial metal detectors indicate the presence of metal in nonconductive materials such as textiles, rubber, oils or liquids, plastics, powders, wood products and concrete.
RF phase detectors and comparators are circuits or instruments that provide a DC output voltage proportional to the difference in phase between two RF signals.
Current testers and detectors check for the presence of current flow in electrical circuits. They are also used to locate current in hidden wires and cables
Ground protection mats and portable roadways are temporary material installations that reduce damage to underlying surfaces from traffic and also provide better traction for equipment and individuals.
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 Detectors

(10 companies)
RF power detectors are devices that detect an RF signal and convert it to an output that corresponds to the RF power. These devices typically connect in-line with coaxial connectors.

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.
