This series of pressure transmitters adopts imported ceramic sensors or diffused silicon sensors with internationally advanced technology,using piezoresistive ceramic diaphragms:E+H capacitive ceramic sensors:using diffused silicon sensors from the American companyGE NovaSensor,combined with high-precision electronic components,and assembled through a rigorous process,Compared with conventional pressure transmitters currently on the market.there are two significant technical differences,one is that the measuring element uses new ceramic materials,which will not cause process contamination to the measured medium.The second is that there is no intermediary liquid inside the measuring element,and it is completely solid-state.The medium pressure acts directly on the ceramic diaphragm, causing displacement of the measuring diaphragm, thereby generating a change in capacitance, which is detected, amplified, and converted into a standard signal output by the electronic components connected to it. Under normal pressure, the diaphragm displacement is 0.025mm;under overpressure, the diaphragm displacement is0.1mm,at this time, the measuring diaphragm contacts the ceramic support and is protected,thus avoiding damage.

Main performance indicators:

1 Using imported ceramic sensors or diffused silicon sensors, with no intermediary liquid, small temperature drift,strong corrosion resistance; sturdy and durable, strong overpressure resistance, with excellent wear resistance and impact resistance.
2 The pure ceramic substrate will not produce process contamination and is suitable for the food and pharmaceutical industries.
3 Zero point and span positive and negative shift are adjustable, easy to operate, and do not affect each other during adjustment;
4 Wide pressure range, from micro pressure10kPato high pressure160MPa;
5 Good stability: ≤0.2％FS/year;
6 Linearity better than0.1％FS;
7 Wide compensated temperature range: －40～+85℃;
8 Electromagnetic interference resistance;
9 Because the sensor uses dry ceramic, without any dielectric, it is minimally affected by temperature and is not affected by installation orientation.
10 Intrinsically safe explosion-proof, explosion-proof gradeiaIICT4;
1l Enclosure protection grade:IP65

   For the two-wire4-20mA output model,the standard power supply isDC24V,when the load resistance is greater than600Ω,for every additional50Ω, an additional1V power supply is required,but thezuimaximum power supply limit isDC45V.When a power supply exceedingDC24Vis required,the output circuit should avoid long-term operation under zero load resistance conditions,and if necessary, a resistor may be connected in series in the output circuit to reduce the power consumption of the output power transistor.Under zero load resistance, thezuiminimum supply voltage isDC12V
