This series of pressure transmitters use imported ceramic sensors or diffused silicon sensors with internationally advanced technology, adopts piezoresistive ceramic diaphragms:E+H capacitive ceramic sensors: adopts diffused silicon sensors fromGE NovaSensor of the United States, combined with high-precision electronic components, and assembled through a strict manufacturing process, compared with conventional pressure transmitters currently on the market.there are two significant technical differences, first, the sensing element uses new ceramic materials, which will not cause process contamination to the measured medium.Second, there is no intermediate liquid inside the sensing element, and it is completely solid-state.The medium pressure acts directly on the ceramic diaphragm, causing the measuring diaphragm to produce displacement, 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, avoiding damage.

Main performance indicators:

1 Uses imported ceramic sensors or diffused silicon sensors, with no intermediate liquid and small temperature drift, strong corrosion resistance; sturdy and durable, with strong overpressure resistance, and excellent wear resistance and impact resistance.
2 The pure ceramic base 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 adjustments do not affect each other;
4 Wide pressure range, from micro pressure10kPa to 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, there is no dielectric at all, so 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 type, the standard power supply isDC24V, when the load resistance is greater than600Ω, the power supply needs to be increased by1V for every additional50Ω, but the maximum power supply limit isDC45V.When a power supply exceedingDC24V is 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, the minimum supply voltage isDC12V
