Level sensors are used to detect liquid or powder levels, or interfaces between liquids. There are two basic level-measurement types: continuous and point or multi-point

Temperature instruments use contact or noncontact methods to measure temperature. Products include dial, digital, industrial and laboratory thermometers; temperature probes, indicators, and sensors; RTD elements and transmitters; and thermistors, thermocouples, thermopiles, and thermal switches. 

Dynamometers are used in motor and engine testing. These devices apply braking or drag resistance to rotation, and measure torque at various speeds and power input levels

Pressure relief valves are self-actuated safety valves designed to relieve excess pressure upstream from the line.

Jet pumps are typically used for drawing water up from a well. These pumps can be used for either shallow or deep well configurations. 

Liquid level switches are used to detect specific liquid levels or interfaces between liquids. These level measurements are indicated via an electrical switching action

Liquid level sensors are used to detect liquid levels or interfaces between liquids such as oil and water or liquids and solids. 

Level switches, all types, is a generic search form for devices that are used to detect liquid or powder levels, or interfaces between liquids. These level measurements are indicated via an electrical switching action

Linear position sensors, all types, is a general search form for all linear position / displacement detection product areas

Level transmitters or level transducers are used to measure the level of a liquid or bulk solid material (as well as slurries) within a specified space. For each measurement, they provide an electrical output that is proportional to the input level

Levels are mechanical or electronic tools that measure the inclination of a surface relative to the earth's surface

Level controllers monitor, regulate, and control liquid or solid levels in a process

Sensor chips are dies incorporating semiconductor circuit elements that are used to convert changes to some physical parameter to an electrical signal

Temperature sensors are measurement devices that infer temperature by sensing some physical characteristic (i.e. resistance, emf or thermal radiation

Metal working lubricants, coolants and fluids are specialized coatings and carriers for metal forming, metal cutting, lapping, polishing, and grinding applications
