Double-flange Differential Pressure Transmitter With Capillary


The double-flange differential pressure transmitter with capillary  is a new type of transmitter with advanced design principles, complete specifications, and easy installation and use. The appearance is completely integrated with the structural advantages of the two most popular and widely used transmitters in the country (Rosemount 3051 and Yokogawa EJA), giving users a refreshing feeling, while also with the traditional 1151, CECC and other series. The equipment can be directly replaced on the installation, with strong versatility and replacement ability. In order to meet the continuous improvement and development of domestic automation level, the double-flange capillary liquid level transmitter has an intelligent function with HART fieldbus protocol in addition to its compact design.

Functional parameters of the double flange level transmitter with capillary:

  ◆Use of objects: liquid, gas and steam

  ◆Measurement range: 0-0.1kPa to 0-40MPa

  ◆Output signal: 4~20mA DC (specially available for four-wire 220V AC, 0~10mA DC output)

  ◆Power supply: 12~45V DC, generally 24V DC

  ◆Load characteristics: related to the power supply. The load capacity at a certain power supply voltage is shown in Figure 2. The relationship between the load impedance RL and the power supply voltage VS is RL ≤ 50 (VS-12).

  ◆Indication table: pointer type linear indication 0~100% scale, and 3 1/2 digit LCD liquid crystal display

  ◆Explosion-proof: a. Flameproof type dIICT5; b. Intrinsically safe type iaIICT6

  ◆ Range and zero point: external continuously adjustable

  ◆ Positive and negative migration: After the zero point passes the positive or negative migration, the absolute value of the upper limit and lower limit of the measuring range and the measuring range cannot exceed 100% of the upper limit of the measuring range. The maximum positive migration is 500% of the minimum calibration range; the maximum negative migration is 600% of the minimum calibration range. The maximum positive and negative migration of the flow transmitter is 10% of the calibration range.

  ◆ Temperature range: Amplifier operating temperature range: -29~+93°C (LT type: -25~+70°C), measuring component for filling silicone oil: -40~+104°C, flanged transmitter filling High temperature silicone oil: +15~+315°C, ordinary silicone oil: -40~+150°C

  ◆Static pressure and overload pressure: 4, 10, 25, 32MPa

  ◆ Humidity: Relative humidity is 0~100%.

  ◆Vibration effect: In any axial direction, when the vibration frequency is 200Hz, the error is ±0.05%/g of the upper limit of the measurement range.

  ◆Power supply impact: less than 0.005%/V of the output range

  ◆Load impact: If the power supply is stable, the load has no effect.

  ◆Installation position effect: The maximum zero error of 0.24kPa can be generated, but it can be corrected, and it has no effect on the range.
