Pressure transmitter

 Pressure transmitter

Yj3051 series Pressure transmitter It is a high-precision intelligent instrument produced by foreign advanced technology. It adopts mature capacitance sensor. It has the characteristics of good long-term stability and high reliability. Through digital technology, the temperature and nonlinearity of the sensor are compensated, which greatly improves the accuracy and range of the sensor. The instrument has HART The communication interface can be tested, configured and calibrated through the specially equipped configuration debugging system, and can also be used with the specially equipped manual operator (and ROSEMONT275 Compatible) on-site configuration and calibration. It is suitable for the measurement of pressure, differential pressure and absolute pressure of all kinds of liquid, gas and steam.

 

Yj3051 series Pressure transmitter Product features:

Yj3051 series pressure transmitter is mainly used to measure the pressure, differential pressure, negative pressure, high static pressure, liquid level and absolute pressure of gas, liquid and steam four 20mA.DC Signal output.

Yj3051 series pressure transmitter includes GP Type (gauge pressure) DP type ( differential pressure ) DR type ( Micro differential pressure ) AP Type (absolute pressure) HP type ( hhp ) LT Type (flange type liquid level transmitter) DP/GP Type (remote differential pressure / Pressure transmitter). The combination of pressure transmitter and intelligent enlarged plate can form intelligent pressure transmitter , It can be achieved by HART The manual operators of the protocol communicate with each other for setting and monitoring.   

1、 3051GP Type of pressure transmitter δ It can be used to measure gauge pressure or negative pressure.

2、 3051AP The absolute pressure transmitter δ One side of the chamber receives the measured absolute pressure signal, and the other side is enclosed into a high vacuum reference chamber. It can measure the absolute pressure of degassing system, distillation tower, evaporator and crystallizer.

3、 3051DP Differential pressure transmitter is mainly used to measure the differential pressure, pressure, liquid level and density of liquid, gas or steam, and then convert it into four 20mA.DC Signal output.   

4、 three thousand and fifty-one Differential pressure transmitter includes DP type ( Basic type ) HP type ( hhp ) and DR type ( Micro differential pressure ) Three types. The combination of the above three types of transmitters and intelligent amplifier board can form an intelligent differential pressure transmitter , It can be achieved by HART The manual operators of the protocol communicate with each other for setting and monitoring.  

5、 3051HP The high static pressure differential pressure transmitter is a kind of differential pressure transmitter which is suitable for petrochemical and power plant 32MPa And can withstand one-way overload pressure without being damaged , Therefore, it can be reliably used for differential pressure measurement of high pressure system.    

6、 3051DR Micro differential pressure transmitter [2] Small differential pressure can be converted into four 20mA.DC Signal, it uses specially designed amplifier circuit board and special temperature compensation technology, stable and reliable performance. It is an ideal product for detecting micro pressure, primary and secondary air volume and air loss in furnace combustion chamber.   

7、 3051LT Flange type liquid level transmitter can be used for precise liquid level measurement of various vessels. There are flat flange and plug-in flange for users to choose. Installation flange standard according to ANSI3 〞、 four Flange rating is 150LB Flange diaphragm material 316L Hastellkin, Monel, tantalum, etc. are suitable for corrosive medium. Our factory can also provide other specifications of installation flange for users.
If the user does not indicate, our factory uses 3150LB Installation flange supply .  

8、 3051DP/GP differential pressure / After the pressure transmitter is equipped with remote transmission sealing device, it becomes 1151DP/GP Remote differential pressure / It still has a pressure transmitter 1151DP/GP differential pressure / It is a reliable measurement method which can avoid the direct contact between the measured medium and the isolation diaphragm of the transmitter
① The measured medium has corrosive effect on the sensitive element of transmitter
② It is necessary to isolate the high temperature measured medium from the transmitter  
③ There are solid suspended solids or high viscosity medium in the tested medium   
(4) the measured medium is easy to solidify or crystallize at the same time when it is led by the pressure pipe  
⑤ To replace the measured medium, the measuring head should be cleaned strictly
⑥ The measuring head must be kept clean and no pollution is allowed.
⑦ Application object: corrosive or viscous liquid
⑧ Note: remote transmitter should not be used in vacuum.

9、 3051DP/GP Remote differential pressure / There are four types of remote pressure transmitter  
① 1191 PFW flat remote transmission device (standard 3″ Working pressure 2.5MPa
② 1191 RTW thread mounted remote transmission device (maximum working pressure 10MPa    
③ 1191rfw flange mounted remote transmission device
④ 1191 EFW plug in barrel remote transmission device (standard 3″ or 4″ , working pressure 2.5MPa

 

Yj3051 series Pressure transmitter Technical parameters:

1. Range ratio: forty 1   

2. Accuracy: the range is three four 5   

3 one one reach ten one For adjusting the range ±0.1%   

4 ten one reach forty one For ±0.05 1+0.1URL/ Range) % range   

5. The range is six seven eight nine 0   

The range ratio is 6 one one reach ten one For adjusting the range ±0.15%   

7 ten one reach forty one When, is ±0.075 1+0.1URL/ Range) % range   

8. Stability : Of the maximum range ±0.15%/6 Months.   

9. Temperature effect: the zero temperature error is within the maximum range ±0.25/55 The total temperature error including zero point and range is ±0.5/55 ℃  

10. Note: for range three nine zero Temperature effect error doubling   

11. Static pressure effect:( DP Zero point error of type I in linear output : Static pressure plus static pressure 10MPa , range four five The zero error of the maximum range is 0 ±0.25% , range three six seven eight The zero error of the maximum range is 0 ±0.5% This is a systematic error , Before installation, zero point of transmitter can be adjusted according to actual static pressure , Eliminate this error. HP Zero point error of type I in linear output : Add static pressure 31.2MPa The zero error is less than that of the maximum range ±2.0% This is a systematic error , Before installation, zero point of transmitter can be adjusted according to actual static pressure , Eliminate this error.   

12. Power supply influence: less than the output range 0.005%/V   

13. Vibration effect: in any axial direction, the frequency is 200Hz The error caused by this method is within the maximum range ±0.05%/g   

14. Load effect: as long as the input voltage of transmitter is higher than 12V There is no load impact in the load work area.   

15. installation position influence: the maximum can produce no more than 0.25kPa This error can be eliminated by correction, which has no effect on the measuring range; the measurement body has no effect on the rotation of flange.
