NP-93420X Pressure transmitter

1. Design features

The output stability, high sensitivity, interference and noise factors have little influence, the corresponding cost of amplifier circuit is reduced, and the resolution is greatly improved.

Special V/I integrated circuit has few peripheral devices, high reliability, simple maintenance, easy maintenance, small size, light weight, and very simple installation and debugging.

Aluminum alloy die-casting shell, three-end isolation, electrostatic spraying protective layer, durable.

4-20mADC two-wire system has strong anti-interference ability and long transmission distance.

LED, LCD, pointer three kinds of indicator headers, easy to read on-site identity. It can be used to measure viscous, crystalline or corrosive media.

Diffusion silicon pressure transmitter is used in dangerous and explosive fields. The product has the characteristics of low current, low voltage and low energy consumption. It belongs to intrinsically safe explosion-proof product and is equipped with explosion-proof certificate.

Using stainless steel material and special protective structure, and a series of protective means such as lightning protection, anti-interference, anti-overcurrent and anti-overcurrent of amplifier circuit, the reliable sealing and anti-corrosion and anti-harsh working environment and pressure are improved, which are completely suitable for the needs of general industrial field measurement and control.
