The main features and technical indicators of smart pressure transmitter

The smart pressure transmitter is a meter that accepts proportional conversion of the pressure variable to a standard output signal. It can convert the physical pressure parameters, such as gas and liquid, sensed by the load cell sensors into standard electrical signals (such as 4-20mADC, etc.) to provide secondary instruments such as alarm indicators, recorders, and regulators for measurement and indication. And process adjustments.

Smart pressure transmitter main features:

1. Super measurement performance for pressure, differential pressure, liquid level, flow measurement;

2, digital accuracy: + (-) 0.05%;

3, stability: 0.25% 60 months;

4, turndown ratio: 100:1;

5, measurement rate: 0.2S;

6, small (2.4kg) stainless steel flange, easy to install;

7. The process connection is compatible with other products to achieve ideal measurement;

8. The only sensor (patented technology) using H alloy sheath in the world achieves excellent cold and thermal stability;

9, using 16-bit computers;

10, standard 4-20mA, with digital signals based on HART protocol, remote control support fieldbus and field-based control technology upgrades.

Smart Pressure Transmitter Specifications:

1, the use of objects: liquids, gases and vapors;

2, the measurement range: 0-7000 ~ 40000kPa;

3, the output signal: 4 ~ 20mADC (special for four-wire system); 220VAC power supply, 0 ~ 10mADC output;

4, power supply: 12 ~ 45VDC, generally 24VDC;

5, load characteristics: with the power supply, at a certain supply voltage with load capacity; load impedance RL and power supply voltage Vs relationship: RL ≤ 50 (Vs-12);

6. Indication table: pointer linear indication 0~100% scale and LCD liquid crystal display;

7, explosion-proof level: a: explosion-proof type (ExdIIBT5 or ExdIICT6); b: intrinsically safe type (ExiaIICT6 or ExibIICT6);

8, range and zero: external continuously adjustable;

9. Positive and negative migration: After the zero point is undergoing positive or negative migration, the absolute values ​​of the upper limit value and lower limit value of the range and measurement range cannot exceed 100% of the upper limit of the measurement range. The maximum positive migration is 500% of the minimum calibration range; the maximum negative migration is 600% of the minimum calibration range;

10, temperature range: operating temperature range: -20 ~ +88 °C;

Brass Casting Parts

In industrial manufacturing or life, you will see many brass parts, most of which are made by investment casting. For example, many accessories such as brass jewelry, brass pendants, brass ornaments and so on that are common in our lives are produced by investment casting. The casting performance of brass in copper alloys is relatively good, but its shrinkage is relatively large, and it is prone to shrinkage holes, cold cracks, deformation and other problems. It is necessary to reduce the pouring temperature as much as possible in the actual pouring to improve this problem. Of course, there are many other processes to improve this shortcoming, such as selecting a good sand mold, setting a riser, or setting a gating system, etc., which can be improved, and the details are discussed and analyzed according to the structure of the workpiece.

Brass casting is not only used in jewelry, pendants, ornaments and other handicrafts in daily life, but also widely used in industry, because copper itself has good corrosion resistance and superior conductivity. There are also many brass castings produced by SCZY. The common ones are some handicrafts, some architectural accessories, and auto accessories. We also support secondary precision CNC machining and surface treatment. Let customers have no worries.
