Meister Flow Meter Co., Ltd. is a professional manufacturer of ceramic pressure transmitters. Welcome to inquire about the price of ceramic pressure transmitters.

Product Overview of Ceramic Pressure Transmitters

The MST133 series ceramic pressure transmitter adopts advanced imported ceramic sensors or diffused silicon sensors, among which the LY133-A type uses piezoresistive ceramic diaphragms, and the BP133-B type uses E+H capacitive ceramic sensors The LY133-C model adopts diffusion silicon sensors from GE NovaSensor in the United States, combined with high-precision electronic components, and is assembled through strict manufacturing processes. Compared with conventional pressure transmitters on the current market, it There are two significant technological differences, one is that the measuring element uses emerging ceramic materials, which will not cause process pollution to the measuring medium The second is that there is no intermediate liquid inside the measuring element, which is completely fixed The medium pressure directly acts on the ceramic diaphragm, causing displacement of the measuring diaphragm and resulting in a change in capacitance. This change is detected, amplified, and converted into a standard signal output by the electronic components connected to it. Normal pressure causes the diaphragm to shift by 0.025mm; When overpressure occurs, the diaphragm is offset by 0.1mm. At this time, the measuring diaphragm is attached to the ceramic bracket and protected, avoiding damage

Main performance indicators of ceramic pressure transmitters

1. Imported ceramic sensors or diffused silicon sensors are used, with no intermediate liquid, low temperature drift, and strong corrosion resistance; Durable and sturdy, with strong resistance to overvoltage and excellent wear and impact resistance.

2. Pure ceramic substrate will not cause process pollution and is suitable for the food and pharmaceutical industries

Zero point, adjustable range with positive and negative transfer, easy to operate, and does not affect each other during adjustment;

4. Wide pressure range, from a slight pressure of 10kPa to a high pressure of 160MPa;

5. Good stability: ≤ 0.2% FS per year;

6. Linearity better than 0.1% FS;

7. Wide compensation temperature range: - 40～+85℃；

8. Anti electromagnetic interference;

Due to the use of dry ceramics and the absence of any dielectric, the sensor is minimally affected by temperature and is not affected by installation direction.

10 intrinsically safe explosion-proof, explosion-proof grade iaIICT4;

1L shell protection level: IP65

The variety of two-wire 4-20mA output has a standard power supply of DC24V. When the load resistance is greater than 600 Ω, an additional 1V power supply is required for every 50 Ω increase, but the maximum power supply limit is DC45V When a power supply exceeding DC24V is required, the output circuit should avoid long-term operation in a zero load resistance state. If necessary, a resistor can be connected in series in the output circuit to reduce the power consumption of the output power transistor The minimum supply voltage at zero load resistance is DC12V.
