A pressure switch is considered one of the common measuring devices used in residential and industrial applications. Tridelta pressure switch is used in modern-day applications, like, hydraulic systems, pumps, HVAC tools, and equipment, etc. The presence of pressure switches ensures the processes have adequate pressure to function effectively.

The apt pressure switch should be chosen

The proper functioning of residential and industrial applications depends significantly on pressure switches. Choosing the right pressure switch is necessary for benefiting the most. While considering buying, several selection criteria need to be considered. When the apt electronic pressure switch is chosen for a specific application, it saves money and increases the durability of the device.

Operating temperature

The operating temperature impacts the type of materials used in manufacturing pressure switches. Several materials can degrade in quality at high temperatures. Stainless steel is one such material that is considered the most suitable for high-temperature service. Therefore, one must choose a tridelta pressure switch made of stainless steel.

Process fluid

The presence of chemical properties determines the kind of materials required for the wetted components of a pressure switch. Seals, ports, the pressure sensing part’s pressurized side, etc., are considered as the wetted parts. The parts are made in a way that they can withstand physical and chemical onset from the process fluid.

Often the wetted parts are degraded because of erosion, corrosion, and oxidation. The commonly used materials include brass, stainless steel, PTFE, and PPE. These materials are robust and have better durability. Hence, pressure fluid is an important aspect to consider while buying a pressure switch.

Range of pressure

Cut-in and cut-out pressures are referred to as the working scope of a pressure switch. The range of pressure identified the scopes and limits for conforming to the cut-in and cut-out pressures in a switch. It is suggested by experts in the field that there must be a 40% to 60% pressure range for the adjustments and changes required.


Accuracy is yet another vital criterion to be considered for choosing pressure switches. When a pressure switch features higher accuracy, automatically their cost increases. Accuracy is measured in the percentage of FS (full scale) value. An electronic pressure switch is said to have better accuracy than typical pressure switches. The accuracy ranges from ±0.2 to 0.5% relying on the manufacturers.

Control system voltage

It identifies the electrical features of the control circuit. One must ensure that the power switch is graded to similar frequency, current, and voltage. In case, the same range is not maintained, the electronic switches will either not activate or render low accuracy. Control circuits used in pressure circuits have common DC voltages like 8, 12, 24, and 30 volts.


Tridelta pressure switch has its uses in multiple applications like water pumps in residences, and industries; air conditioners, and refrigerators; hydraulic systems; boilers, and furnaces; compressed air systems, and hydraulic systems, etc. When the apt pressure switch is selected, its utilization can be executed properly and better functioning of the applications is guaranteed.
