1, Structural characteristics
Axial installation: The connector is located behind the dial, and the axial outlet is connected
With fixed flange: used for panel embedded installation, easy to fix, beautiful and neat
Electric contact function: It can set upper and lower pressure limits, and when the set value is reached, the contact will act to achieve alarm, control, and interlock protection
Common surface diameters: φ 60, φ 100, φ 150
Common structure: Axial belt with front edge (flange), model generally marked as ZT type
2, Working principle
The measured pressure acts on the Bourdon tube, causing it to undergo elastic deformation, which drives the pointer to rotate through the movement. When the pointer touches the pre-set upper/lower limit electrical contact, the circuit is turned on or off, outputting a switch signal to achieve automatic control or sound and light alarm.
3, Typical parameters
Accuracy level: 1.6 level, 2.5 level
Measurement range: -0.1~0~100MPa
Contact capacity: commonly 30VA, 220VAC/24VDC
Shell material: iron shell or stainless steel 304
Table: Ordinary Glass/Safety Glass

4, Application scenarios
Hydraulic and pneumatic systems
Control of water pump and air compressor
Pressure monitoring of HVAC and water supply pipelines
Machine tools, injection molding machines, pressure vessels
