A carbon dioxide sensor is a machine used to detect the concentration of carbon dioxide. Carbon dioxide is one of the raw materials for photosynthesis of green plants, and 95% of the dry weight of crops comes from photosynthesis. For those unfamiliar with air quality sensors, choosing the right sensor can be challenging. Today we are going to discuss the types of CO2 sensors and their pros and cons.

Angle seat valves are 2-way, 2-position pneumatic piston valves. The piston pneumatic actuator provides linear motion to lift the seal from its seat. Because the seat is positioned at an angle, flow obstruction is minimal in the open position, resulting in excellent flow and low pressure losses. They are used to regulate the flow of liquids, gases, vapors, vacuum and even corrosive fluids. Angle seat valves can operate in high temperature and high viscosity media even at zero differential pressure. Rugged design makes these angle seat valves a best choice for harsh applications, and they have a very high cycle life.

The piston pump is a type of positive displacement pump, wherein said high pressure seal with said reciprocating piston. Piston pumps can be used to transport liquids or compressed gases. They can operate over a wide range of pressures. High pressure operation can be achieved without a strong influence on the flow rate. Piston pumps can also handle viscous media and media containing solid particles. This pump type functions through a piston cup, an oscillating mechanism (where a downward stroke causes a pressure differential), and a filled pump chamber (where an upward stroke forces the pump fluid out for use). Piston pumps are typically used in scenarios where high, consistent pressure is required, as well as in water irrigation or delivery systems.
