Dedicated to food, pharmaceutical industry pressure measurement, sanitary interface installation, monocrystalline silicon hygienic pressure transmitter affordable, provide accurate, stable and reliable armature color to pressure measurement.
Monocrystalline silicon hygienic pressure transmitter is used to measure the liquid, gas or steam level, density and pressure, and then transformed into a 4-20mADC HART current signal output. It can also communicate with RST375 handheld terminal or RSM100 Modem for parameter setting and process monitoring.
Monocrystalline silicon hygienic absolute pressure transmitter principle

6, high stability, reliability and very low temperature drift, hygienic absolute pressure transmitter zero, precision and repeatability for many years unchanged, long-term maintenance-free operation
7、Three alarm current output modes are user-selectable.
8, sanitary type absolute pressure transmitter can be freely programmed configuration, bus standard 4-20mA/HART output.
The relationship between adiabatic pressure, gauge pressure and vacuum degree
1, commonly used pressure transmitter is generally gauge pressure transmitter, pressure transmitter readings shown in the transmitter pressure than the value of atmospheric pressure, rather than the actual value of the pressure within the transmitter. If the pressure transmitter inside, outside pressure is equal, the pressure transmitter reading is zero. The actual value of the pressure is called armature to the pressure (absolute pressure), the pressure value read from the pressure transmitter is called gauge pressure, the relationship between the two: absolute pressure = atmospheric pressure + gauge pressure
2, the degree of the vacuum gauge is the actual pressure measured than the atmospheric pressure to be lower than the value, known as the degree of vacuum. Vacuum and the relationship between the absolute pressure is: absolute pressure = atmospheric pressure - vacuum
So the higher the vacuum, the lower the absolute pressure. Vacuum is also the armature of the table pressure to the value, for example, the vacuum is 90kPa, according to the table pressure is -90kPa, so the industry will also be known as the vacuum of negative pressure.
