convert the absolute or gauge pressure of the measured medium into 4~20mA, 0~5VDC, 0~10VDC, and 1~5VDC. Such as standard electrical signals.

High-quality sensors hermetically sealed soldering technology,
and a complete assembly process ensures excellent quality and performance.
The product is available in a variety of interface styles.
And a variety of lead styles to best meet customer needs.
And is suitable for use with a variety of measurement and control equipment.

Explosion proof pressure transmitter working principle

The explosion-proof pressure transmitter consists of an integrated intelligent sensor and peripheral circuits.

The sensor part is composed of a pressure sensor, a signal modulation circuit, a dedicated digital processing chip, a temperature sensor and data memory, and the peripheral electronic circuit part is composed of an LCD display, function keys and an EMC circuit.

The pressure signal is converted into an electrical signal by the pressure sensor. And the electrical signal is modulated. And sent to a dedicated digital processing chip for data processing.
And then converted into a 4~20 mA output signal corresponding to the pressure signal.
And the HART digital signal is superimposed on the current signal for communication.

Potentially explosive environment.

Such as: flammable gas, dust environment, oil refinery, petrochemical plant, gas station, gas station, etc., explosive gas environment.

Under atmospheric conditions, a mixture of combustible substances in the form of gas, steam or mist and air. After being ignited in the mixture, the combustion will spread throughout the environment of the unburned mixture.

Such as: CH4, C2H2, C2H4, NH3, CO, C2H5OH and other explosion-proof electrical equipment.

Intrinsically safe VS explosion-proof

The explosion-proof of the current pressure transmitter: mainly two forms of isolation explosion-proof and intrinsically safe explosion-proof.

Intrinsically safe explosion-proof:

“i” (Intrinsically safe electrical equipment and related equipment) Intrinsically safe circuits, circuits that cannot ignite the specified explosive gas or steam under the specified test conditions, under the specified test conditions, the electric sparks and thermal effects generated under the specified fault state . Intrinsically safe electrical equipment: All circuits are intrinsically safe electrical equipment.

Example: Intrinsic Safety: Ex ia II BT4

Flameproof:

It refers to the electrical equipment that encloses the components that can ignite the explosive mixture in a shell, and the shell can withstand the explosive pressure of the internal explosive mixture and prevent the explosion of the surrounding explosive mixture.

For example: Flameproof: Ex d II CT6
