Product details
1、 Product Overview
Electric contact pressure vacuum gauge and electric contact vacuum gauge are made of copper and copper alloys, which have no corrosive effect, no explosion hazard, and are non crystalline and non solidifying liquids, gases, and other media (pressure) and negative pressure When the pressure reaches the predetermined value, the control circuit can be connected or disconnected with the help of a contact device, and an electrical signal can be emitted at the same time.
Electric contact pressure vacuum gauge is used to measure the pressure and negative pressure of non crystalline and non solidified liquids, gases, and other media such as copper and copper alloys, which have no corrosive effect and no explosion hazard When the pressure and negative pressure reach the predetermined values, the magnetic electric contact device can be used to connect or disconnect the control circuit
Electric contact vacuum gauge is used to measure the negative pressure of liquids, gases, or vapors that do not corrode copper and copper alloys And when the negative pressure reaches the predetermined value, an electrical signal is emitted to turn on or off the control circuit

3、 Model differentiation
Y represents pressure gauge; Z represents damping or vacuum; B represents explosion-proof or standard; J represents precision or rectangle; A represents the ammonia meter; X represents a signal or electrical contact; XC represents magnetic assisted electrical contact; P represents the membrane; E represents the membrane box; F represents anti-corrosion; N represents shock resistance; T represents the spring tube; B represents stainless steel. In addition, the commonly used pressure gauge models are as follows: YTF stands for stainless steel pressure gauge; YA stands for ammonia pressure gauge; YXC represents an electric contact pressure gauge; YZ represents vacuum pressure gauge; YY represents acetylene pressure gauge; YO stands for heat-resistant pressure gauge; YH stands for hydrogen pressure gauge.
4、 Specification differentiation
Pressure gauge threads are divided into metric, imperial, and American systems.
1. Metric system:
M20×1.5
20 "represents a diameter of 20mm at the threaded part of the joint;
"1.5" represents a distance of 1.5mm between the screw threads;
M "represents a pipe thread with a tooth tip angle of 60 °;
In general:
The size of the connecting thread with a diameter of 40 is M10 × 1;
The size of the connecting thread with a diameter of 60 is M14 × 1.5.
The connecting thread size for diameter 100 and 150 is M20 × 1.5;
