Description
Pressure Switch Model 501/7D
This model 501/7D pressure switch is designed to provide reliable performance in a variety of industrial applications. With diaphragm-type sensors, these switches feature high sensitivity, especially at low pressure ranges, making them an ideal choice for applications that require fast and accurate response.
Key Features and Materials
Diaphragm Sensor: Uses a responsive diaphragm sensor to detect pressure changes with high precision.
Durable Materials: The housing is made of stainless steel, which offers excellent corrosion resistance. This makes it suitable for harsh working environments and ensures a longer product life.
Media Suitability and Pressure Range
These pressure switches are highly versatile and can be used with a variety of liquid and gaseous media, including:
Neutral Gas
Water
Hydraulic Oil
Lubricating Oil
Light Fuel
The adjustable pressure range (set point) is very flexible, ranging from 0 to 1 Mpa. This range is equivalent to 0 to 145 PSI or 0 to 10 Bar, providing flexibility for various technical requirements.
Important Warnings and Usage Guidelines
Although this switch is robust, it is very important to pay attention to the Max.
Applications
Pressure Switch Model 501/7D
- Pneumatic and Hydraulic Systems: It’s used to control the pressure of neutral gases, water, hydraulic pressure oil, and lubricating oil. This makes it ideal for managing the operation of pumps and compressors.
- Fuel and Oil Systems: The switch is designed to handle light fuel, allowing it to be integrated into systems that require pressure monitoring for these types of fluids.
- Corrosive Media: Certain specifications of the 501/7D have a stainless steel sensor shell, which makes them suitable for use with corrosive media, broadening their range of applications.
- Safety and Control: The primary function of a pressure switch is to act as a safety device or a control mechanism. By turning a circuit on or off at a specific pressure, it can prevent over-pressurization, under-pressurization, or other conditions that could damage equipment or affect system performance.
