The diaphragm is an important part of instruments such as transmitters. The diaphragm acts as an isolation of the measuring medium in the transmitter, preventing the medium from entering the inside of the meter head and damaging the components, and also senses the pressure value and communicates it to the pressure element. Today we will introduce several commonly used diaphragms. 1. Rubber diaphragm Rubber diaphragms are mainly used in valves, regulating valves, automatic mechanical follow-up devices, switches and counters for flow, pressure, differential, liquid level, constant temperature volume heat compensation, etc. Its advantages lie in high reliability, good compounding, long working life and low cost. It is mainly used in some harsh working conditions. 2. Cloth diaphragm The material composed of the diaphragm is made of rubber elastomer NBR as the main material, and the reinforcing cloth (nylon, glass fiber, Nomex, and other special reinforcing cloths) is the skeleton, the life of the diaphragm is more than 1.5 million times, and the thickness is 0.2-5mm, which can also be corrosion-resistant and anti-aging when applied to differential pressure transmitters, and is mainly used in some areas around mechanical vibration. 3.316L diaphragm The 316L diaphragm is the most common diaphragm in the industrial sector. The material is made of 316L stainless steel. The thickness is only about 0.1mm. It has excellent corrosion resistance. The 316L stainless steel diaphragm can withstand both high and low temperatures. Pressure transmitters, level transmitters, differential pressure transmitters, etc. are usually made of 316L stainless steel diaphragms. The diaphragm used in the transmitter is extremely sensitive, and during use, it is forbidden to touch any human touch, and the damage of the transmitter diaphragm is very easy to cause the entire transmitter to be unusable. In the selection process of the transmitter, the material of the diaphragm should also be considered. Different measuring media have different requirements for the diaphragm.
