Diaphragm/Diaphragm Seismic Pressure GaugeDetailed product description：

1. Overview

YML and YMF diaphragm/diaphragm shock resistant pressure gauges consist of two main parts: a diaphragm isolation device and a pressure gauge. Widely used in industries such as petroleum, chemical, pharmaceutical, food, paper, etc. to measure the pressure of liquid media with strong corrosiveness, high viscosity, easy crystallization, and containing solid particles.
The vibration resistant diaphragm pressure gauge effectively eliminates the influence of medium pulsation and environmental vibration due to the use of durable pressure gauges, making the instrument indication stable and reliable, and also improving the service life of the instrument.
