Although the diaphragm pressure gauge and the diaphragm-seal pressure gauge both use the diaphragm to isolate the measurement medium, Avoid substances such as strong corrosion and high viscosity affecting the instrument.

But their measurement principles are different:

The diaphragm part of the diaphragm pressure gauge is integral with the instrument and cannot be separated. The diaphragm adopts corrugated film,Is the elastic element of the diaphragm pressure gauge, A connecting rod is fixed between the diaphragm and the movement.When pressure causes the diaphragm to deform elastically, The connecting rod connected with the diaphragm will drive the gear of the movement, The gear of the movement drives the pointer to rotate to show the pressure value.

The diaphragm-seal pressure gauge is actually a diaphragm isolator added to the general spring tube pressure gauge. The isolator is removable, The diaphragm is only used for isolation. The true elastic element is the spring tube in the gauge.

These differences make the two gauges suitable for different environments, For example, a diaphragm-seal pressure gauge cannot measure a micro pressure, but a diaphragm pressure gauge can.

So everyone should pay attention to the distinction when purchasing!
