20S-090 is a versatile range of multi-purpose pressure switches from Automation Direct. It serves as a pressurization system regulator and is designed to provide reliable switching between two states when the pressure limit is exceeded or not met. The device consists of two contacts and a bellows, which is pressure-sensitive. When the bellows is in contact with a pressurized system, it is forced to expand or contract and trips the contacts once the preset limit is reached. This is the basic working principle of the device.

The 20S-090 has a variety of applications due to its versatility. It can be used for process control, fluid level monitoring, automatic pump control, hydraulic pressure measurement and control, air pressure, refrigeration, and many other similar applications. It is highly customizable, as the user can modify the bellows’ pressure range and pressure values to meet the specific requirements of the application. Moreover, the device can be used in both hazardous and non-hazardous environments.

In terms of technical specifications, the 20S-090 pressure switch has a voltage rating of 250V AC, a power rating of 3W, and an ambient temperature range of −25 to +75 °C. It is designed to withstand difficult conditions and is certified to the EN 415-2 standard. The device also features a unique “Fail-safe” feature, which ensures that it shuts off when the power is disconnected, safeguarding against overpressure or underpressure. Additionally, the device has an adjustable differential range of 0.2 to 4 bar, which allows users to customize it according to their particular needs.

To summarize, the 20S-090 is a versatile multi-purpose pressure switch from Automation Direct, which has many applications in various industries. It features a Fail-safe feature, adjustable differential range, and is certified to EN 415-2. The device has a voltage rating of 250V AC, a power rating of 3W, and an ambient temperature range of −25 to +75 °C.
