Pressure switch type KPI35, range from 0.2 to 8 bar, mechanical differential: 0.4 to 1.5 bar 060-121766

Pressure switch for regulation and monitoring

This KPI35 pressure switch is a reliable device designed for regulation, monitoring and alarm systems in industry. It is suitable for applications with both liquids and gases. Its versatility results from a wide range of pressures – from 0.2 to 8 bar – and the ability to set a mechanical differential in the range of 0.4 to 1.5 bar. This allows for precise adaptation of the device to the specific needs of the installation.

Design and application

The KPI35 pressure switch is equipped with a single-pole double-throw (SPDT) switching contact system, providing flexibility in connecting various circuits. Therefore, it can be used not only for simple on/off switching of devices, but also for more advanced control functions. The diaphragm inside the pressure switch changes volume proportionally to the pressure, and the omega spring ensures fast and precise switching of the contacts – the so-called snap function.

It will find application in:

• Heating, ventilation and air conditioning (HVAC) systems
• Industrial machines and equipment
• Irrigation systems
• Air compressors
• Hydraulic installations

Characteristic features

• Durable construction: The pressure switch housing is vibration resistant, guaranteeing reliable operation even in harsh industrial conditions.
• Easy installation: It has a 1/4 inch BSPP external gas thread, which facilitates integration with existing installations. The dimensions of the device are 48 mm (width), 129 mm (height) and 92 mm (depth).
• Safety: Meets CE standards according to EN 60947-4/-5 and 73/23/EC. Protection class IP30 provides basic protection against touch and ingress of solid objects.
• Wide range of applications: The ability to operate at a maximum working pressure of up to 18 hPa makes it suitable for various applications.
• Precision: Adjustable mechanical differential allows for accurate adjustment of the switching point to the specifics of a given installation.
