China Factory Explosion Proof High Temperature Pressure Transmitter

                                      China Factory Explosion Proof High Temperature Pressure Transmitter

ML2000A series pressure transmitter is isolation packaged by low temperature welding of metal and export MV signal through inside circuit adjustment, then convert signal into standard two-wired current signal output to pressure through amplifying circuit. It is used to measure pressure, liquid level in industry automatic controlling process. This product applies integrative stainless steel structure, all-solid design, which can be used in severe environment. It is of easy installation with high shock resistance and impact resistance. Pressure transmitters are used to measure the pressure of liquids, fluids, and gases in the process industry. Also, known as pressure transducers, these equipment do more than just checking the pressure of the working equipment.

Pressure transmitter is a device for pressure measurement of gases or liquids. Pressure is an expression of the force required to stop a fluid from expanding, and is usually stated in terms of force per unit area. A pressure transmitter usually acts as a transducer; it generates a signal as a function of the pressure imposed. For the purposes of this article, such a signal is electrical.

Pressure sensors are used for control and monitoring in thousands of everyday applications. Pressure sensors can also be used to indirectly measure other variables such as fluid/gas flow, speed, water level, and altitude. Pressure sensors can alternatively be called pressure transducers, pressure transmitters, pressure senders, pressure indicators, piezometers and manometers, among other names.

The pressure transducer consists of a pressure-sensitive element, such as a diaphragm, with a constant area. The fluid pressure causes the diaphragm to deflect. The pressure transducer also consists of a transduction element. This transduction element converts the deflection sensed by the diaphragm into an electrical output signal. This signal will increase or decrease proportionally to the pressure change. Therefore, device calibration is critical to ensure that the pressure is within the range of the specifications.

Pressure transducers require a power supply to produce electrical signals. The signal is commonly 4-20 mA or 0-10 V DC. Some systems may also use a combination of AC and DC power. The 4-20 mA signal is a widely used standard in the industry. It uses a 2-wire configuration while DC voltage output uses a 3-wire configuration. The 4-20 mA signal can be used over long distances and is less sensitive to interference than a DC signal.

A pressure transducer should not be confused with a pressure switch. A pressure switch is a device that operates an electrical contact when a preset fluid pressure is reached. Read our pressure switch technical article to learn more about them.
