Pressure gauges, which are devices that measure the internal pressure of media within a system, are among the most often used instruments in any given industrial facility.

Pressure measurement is, along with temperature measurement, one of the most important measurements for operations in a wide variety of applications – especially industrial applications – and it is essential in ensuring both the quality of a product and the safety of a facility and its personnel.

Level sensors are components used in fluid control systems to determine the level of a tank or container. They can determine the levels of different types of free-flowing media such as liquids, powdered solids, and granular solids. They provide an electrical signal which automatically communicates when connected control valves should be opened or closed.

There are multiple types of level sensors, and each type uses a different method of gauging the level of media within the tank or container. This means that varying types of level sensors work in different ways, using distinct technologies and processes to complete their measurements.

A pressure switch is a device that operates an electrical contact when a preset fluid pressure is reached. The switch makes an electrical contact on either pressure rise or pressure fall from a certain preset pressure level. Pressure switches are in a wide range of industrial and residential applications like HVAC systems, well pumps, furnaces, etc

A temperature gauge is a device used for the accurate measurement and reading of temperature gradient. The term temperature gauge usually, though not always, refers to a device showing readings on a numbered dial.

Temperature measurement gauges fall into two broad categories - contact thermometers, and non-contact thermometers. People often buy a temperature gauge to help monitor ambient temperatures at the mounting location. These are non-contact sensors.
