Pressure Sensor Transmitter

Pressure Sensor Transmitter Working principle

The NP93420 series pressure transmitter in general sense is mainly composed of load cell sensor (also known as pressure sensor), measuring circuit and process connector. It can change the physical pressure parameters such as gas and liquid felt by the load cell sensor into the standard electrical signal (such as 4~20mADC, etc.), to supply indicating alarm, recorder, regulator and other secondary instruments for measurement, indication and process adjustment.

Pressure transmitter is a kind of instrument that accepts pressure variable and converts pressure variation into standard output signal in a certain proportion after transferring the sense. The transmitter output signal is transmitted to the central control room for pressure indication, recording or control.

Pressure Sensor Transmitter Technical Parameter

Pressure Sensor Transmitter Application

Widely used in petroleum, chemical industry, metallurgy, electric power, light industry, building materials, medicine, environmental protection, scientific research, and other enterprises and institutions, realize to test the process fluid pressure, and is suitable for various occasions all-weather environment and all kinds of corrosive liquid.

Pressure Sensor Transmitter Characteristics

• The output is stable, the sensitivity is high, the influence of interference and noise is relatively small, the corresponding cost of amplifier circuit is reduced, and the resolution is greatly improved.
• Special V / I integrated circuit, few peripheral devices, high reliability, simple maintenance, easy, small volume, light weight, easy to install and debug.
• Aluminum alloy die-casting shell, three-end isolation, electrostatic spray plastic protective layer,durable.
• 4-20mA DC two-wire signal transmission, strong anti-interference ability, long transmission distance.
• LED,LCD, pointer three indicator heads, site reading is very convenient. Can be used to measure viscous,crystalline and corrosive media.
• When used in dangerous and explosive fields, diffused silicon pressure transmitter is adopted. The product has the characteristics of low current, low voltage and low power consumption. It belongs to intrinsically safe and explosion-proof product and is equipped with explosion-proof certificate.
• Adopting a series of protective measures, such as stainless steel material and special protective structure, and amplifying circuit to protect against lightning strike, anti-jamming, anti-overvoltage, overcurrent, etc., it improves the ability of reliable sealing and anticorrosion and anti-adverse working environment. Fully suitable for general industrial field measurement and control needs.
