100mm 4" Stainless Steel Shock-Resistant Magnetically Assisted Gold-Plated Electric Contact Pressure Gauge with Oil Filling Aviation Plug 220V-380V 30va-50va

Product Description

ApplicationThe shock-resistant electric contact pressure gauge has excellent performances such as pulsation resistance, impact resistance, and vibration resistance. It is widely used in petroleum, chemical, chemical fiber, metallurgy, power stations and other industries, to measure the pressure of various fluid media in the process that require pulsation, impact or vibration resistance. Equipped with an electric contact device, this pressure gauge can be used for on-site indication and control the circuit C contact switch of the pressure control system.
Thereby achieving remote transmission and automatic control. When the pressure reaches a predetermined value, the control circuit can be turned on or off to achieve the purpose of automatic control. The shock-resistant structure of this pressure gauge can effectively suppress the jitter of the pointer, protect the contacts, make the indication clear, and the electrical signal switching reliable and stable. Features1. One contact device is a magnetically assisted gold-plated contact contact, which is surface contact, reliable in contact, and resistant to ablation.
2. Another contact device is reed switch contact, which can transmit signals well under low voltage (24V, 12V) without arcing phenomena. It has fast response speed and long service life. Its advantage is that the contact switch is isolated from the atmosphere, and there is noble gas or vacuum state in the tube, which can reduce the oxidation and carbonization of the contact. The sealed design can prevent external steam and dust impurities from corroding the contact. The reed switch contact enables the electric contact pressure gauge to be used in low- voltage systems, which makes the low voltage system intelligent. ParametersDiameter: φ100mm, φ150mm
