Description
Y-63B-FZ, Y-63B-F, Y-60B-F, Y-60B-FZ stainless steel pressure gauges
Product introduction:
Shanghai Automation Instrumentation Co., Ltd. pressure transmitters and Y-63B-FZ, Y-63B-F, Y-60B-F, Y-60B-FZ stainless steel pressure gauges are the most widely used and most common. Transducers are broadly divided into pressure transmitters and differential pressure transmitters. Transmitters are commonly used to measure pressure, differential pressure, vacuum, and liquid level. Transmitters are divided into two-wire system (current signal) and three-wire system (voltage signal). There are more two-wire system (current signal) transmitters. There are more intelligent transmitters and non-intelligent transmitters. Yes Pneumatic and electric are mostly divided into electric transmitters. In addition, there are intrinsically safe and explosion-proof types according to the application. In the selection, you should choose according to your needs.
I. Compatibility of the tested medium
In the selection, we must consider its medium to pressure interface and sensitive components. We must also consider the material of pressure interface and sensitive components, otherwise the outer diaphragm will be corroded and damaged in a short time after use, which will cause equipment and personal accidents. Material selection is very important.
Impact of medium temperature and ambient temperature on products
When selecting the type, the temperature of the measured medium and the ambient temperature should be considered. If the temperature is higher than the product's temperature compensation, it will easily cause product measurement data to drift. When selecting, you must consider the actual working environment of the transmitter to avoid temperature sensitivity to pressure The core caused an inaccurate measurement.
Selection of pressure range
In the selection, the working pressure level of the equipment must be considered, and the pressure level of the transmitter must be consistent with the application.
Selection of pressure interface
In the selection process, strictly implement the size of the pressure interface used by the user, select the appropriate and correct thread connection form, and confirm the product outline drawing, or the manufacturer can provide samples;
V. Selection of electrical interface
When selecting a model, you must repeatedly confirm the user signal acquisition method and field wiring conditions, and the sensor signal must be connected to the user acquisition interface; choose the correct electrical interface and signal method.
Six, pressure type selection
Instruments that measure absolute pressure are called absolute pressure gauges. For ordinary industrial pressure gauges, the gauge pressure is measured, that is, the pressure difference between absolute pressure and atmospheric pressure. When the absolute pressure is greater than the atmospheric pressure value, the measured gauge pressure value is positive, which is called positive gauge pressure; when the absolute pressure is less than the atmospheric pressure value, the gauge pressure value is negative, which is called negative gauge pressure, that is, the degree of vacuum. The instrument that measures the degree of vacuum is called a vacuum gauge.
