YXCh Series reed electric contact pressure gauge

◆ Model: YXCh100 YXCh150

◆ Application: Reed electric contact pressure gauge is suitable for measuring the pressure of liquids, gases or vapors without explosion hazard, no crystallization, no solidification, and no corrosive effect on copper and copper alloys. When it is equipped with a suitable circuit system, it can send an alarm or automatic control to the pressure system to be measured and controlled.

Reed electric contact pressure gauge improves the contact into a vacuum device, which avoids the poor contact caused by oxidation of the contact, so it has the characteristics of fast and sensitive response and reliable contact contact, and is a rookie that can replace the magnetic contact pressure gauge under the working conditions of low power and low voltage.

◆ If it is necessary to make a shockproof type pressure gauge, it can be filled with glycerin or silicone oil.

The Reed electric contact pressure gauge features a 1.6 accuracy class, meeting the requirements for general pressure monitoring. It provides stable readings with controllable errors, making it ideal for installation in piping systems, air compressors, water treatment equipment, and general mechanical devices.
According to the parameter table, a wide range of measurement ranges are available, including:
● Vacuum range: -0.1 to 0
● Negative pressure range: -0.1 to -0.06 / -0.1 to -0.5 / -0.1 to -2.4 MPa
● Positive pressure range: 0 to 0.1 / 0 to 0.6 / 0 to 1.6 / 0 to 10 / 0 to 25 / 0 to 160 / 0 to 250 MPa
This wide range of measurement options allows the pressure gauge to be used in various scenarios, from micro-pressure monitoring to high-pressure system control, and is particularly suitable for industrial environments with multiple operating conditions.
The Reed switch control offers high reliability and sensitive operation.
The reed switch contact structure has the following advantages:
No sparks, no mechanical friction, and long contact life;
Fast action and high repeatability, suitable for frequent start-stop control.
