The 6773 Double Diaphragm Pressure Switch from HergaPrecision, Safety, and Reliability in Coffee Machines

Pressure Switch27/02/2025amironicLTD

Enhancing Coffee Machine Performance with Advanced Pressure Control

In the competitive world of coffee machines, precision and safety are critical. Consistent pressure control directly influences the quality of brewed coffee, the longevity of the machine, and overall user experience. The 6773 double diaphragm pressure switch from Herga Technology is designed to meet these high demands, offering unparalleled accuracy, durability, and safety in pressure regulation. Now, available in Israel exclusively through Amironic, this innovative switch is an essential component for manufacturers looking to enhance their coffee machines with cutting-edge technology.


What is a Double Diaphragm Pressure Switch?

A double diaphragm pressure switch belongs to the family of pressure-activated switches that monitor and respond to changes in gas or liquid pressure. Unlike conventional switches that rely on a single diaphragm, a double diaphragm design provides an additional level of safety and precision. This ensures stable and accurate pressure measurement, making it a critical component in applications where reliable pressure monitoring is essential.

Technical Overview of the 6773 Double Diaphragm Pressure Switch

The Herga 6773 stands out due to its compact design, robust build, and superior performance. Below are some of its key specifications:

  • Activation Pressure: Adjustable between 20 mbar and 690 mbar
  • Operating Temperature Range: -5ºC to +70ºC
  • Body Material: Durable Thermoplastic for longevity and resistance
  • Electrical Ratings: Available in multiple configurations, including 0.1A gold contacts for enhanced conductivity and 21A high-power applications
  • Connection Options: Side or back entry spouts, with different orientations and lengths
  • Double Insulation: Ensures safety when used with conductive media
  • Temperature Compensation Options: Available to optimize performance in varying environmental conditions

This switch is engineered to perform in demanding conditions while ensuring safety and efficiency in high-performance applications.


Application in Coffee Machines: A Crucial Safety Component

Modern coffee machines require precise pressure regulation to maintain optimal performance. The 6773 double diaphragm pressure switch plays a vital role in ensuring the correct pressure balance, particularly in the nozzle set. Here’s how it works:

  1. During normal operation, a coffee machine’s jet system generates a back pressure of approximately 15 PSI. This pressure is crucial for pump efficiency and coffee quality.
  2. The 6773 switch continuously monitors the pressure inside the machine.
  3. If the pressure exceeds the set threshold, the diaphragms detect the deviation and trigger the automatic shut-off mechanism.
  4. This prevents overpressure damage, ensuring machine longevity and user safety.

With its ability to instantly react to pressure anomalies, the 6773 ensures smooth and uninterrupted operation while protecting internal components from excess stress.


Why Choose the 6773 Double Diaphragm Switch for Coffee Machines?

The Herga 6773 is the ideal choice for coffee machine manufacturers due to its unique combination of precision, safety, and durability. Key benefits include:

✔ Enhanced Coffee Quality – Maintains stable pressure for consistent brewing results.
✔ Superior Machine Protection – Prevents damage from excessive pressure build-up.
✔ Compact & Easy Integration – Fits into tight spaces, making it ideal for coffee machines.
✔ High Reliability & Safety – Double diaphragm design adds an extra layer of safety.
✔ Long-Lasting Durability – Built with robust materials to withstand harsh conditions.

By integrating the 6773 double diaphragm switch, manufacturers ensure their coffee machines operate with maximum efficiency and reliability.
