Differential pressure switches | Riels Instruments

Pressure state detectors, better known as pressure switches, detect abnormal pressure states in industrial equipment, e.g. a compressor, a tank, etc.

Due to their simple construction, based on mechanics, differential pressure switches are highly reliable instruments that do not need to be electrically powered and are mainly installed on plants or equipment, to prevent dangerous failures or malfunctions in the plant. 
The entire line of differential pressure switches is also manufactured in an Atex explosion-proof version for applications in potentially explosive areas.

What is a differential pressure switch?

A differential pressure switch detects the difference between two pressures applied in two environments with different pressures. Due to their simplicity of construction, based on mechanics, differential pressure switches are instruments that do not need to be powered electrically and are mainly installed on systems or equipment, in order to prevent faults or malfunctions that are dangerous to the system.
