DW803/804 Diffuse silicon pressure transmitterDetailed product description：

Product Introduction

The DW803/804 pressure transmitter is a high-precision and high stability pressure transmitter made of carefully selected American IC sensors diffused silicon pressure sensors and precision single-chip integrated transmitter circuits. It can reliably convert the measured pressure signal into a 4-20mA DC standard current signal. AT803 is a standard industrial pressure transmitter, while AT804 is a miniaturized pressure transmitter. The product is mainly used for pressure measurement and control in the petroleum, chemical, power, metallurgy, light industry, pharmaceutical, and food industries.
All-weather structure
The transmitter housing is a fully sealed structure, and a wear-resistant and durable epoxy resin paint is sprayed on the housing cover to prevent moisture, water, dust, and corrosion. Can work in harsh environments and outdoor conditions. The transmitter has a small volume and light weight, can be installed on process pipelines, and can be supported. Compared with transmitters that require installation bases and brackets, it greatly reduces installation and maintenance costs. At the same time, it can withstand overload pressure three times the measurement range to protect the transmitter from impact overload damage.
