RYB162 Explosion Proof Differential Pressure Transmitter

A. Product Overview

The RYB162 Explosion Proof Differential Pressure Transmitter is an industrial pressure measuring instrument used to monitor the difference between two pressure points. It is suitable for oil and gas, petroleum, chemical, metallurgy, electric power, water conservancy, environmental protection and scientific research applications where stable differential pressure monitoring is required. The product page highlights imported pressure sensor technology, computer-based temperature compensation, an integrated wiring box, convenient calibration and digital display support.

This transmitter is designed for liquid, gas, oil, water, fuel and corrosive fluid pressure measurement. Its intrinsically safe explosion-proof design makes it suitable for hazardous-area applications where ordinary pressure transmitters may not be safe to use. The product specification includes 0 to 3.5 MPa measuring range, 0.5 percent accuracy, 200 percent overload capacity, 4-20mA and RS485 output, 24VDC power supply, 4-digit LCD display, G1/2 thread and stainless steel interface material.

The uploaded QYB16X data sheet also describes the differential pressure transmitter construction as a fully welded differential pressure measuring element, with silicone oil filled between the sensor chip and corrugated diaphragms. It also mentions a diffused silicon piezoresistive differential pressure sensor with SS316L isolation diaphragm, temperature compensation and LED or LCD display options.

B. Working Principle

The RYB162 works by measuring the pressure difference between the high-pressure side and the low-pressure side. The measured differential pressure acts on internal diaphragms, and the pressure is transferred through silicone oil to the sensitive sensor chip. The sensor converts this pressure difference into an electrical signal.

The sensor signal is processed by the transmitter circuit and converted into standard industrial outputs such as 4-20mA and RS485. The differential pressure value can also be shown on the digital display for local monitoring. The data sheet explains that the sensor output has a linear relationship with differential pressure, which helps the transmitter measure and transmit pressure values accurately.

C. Why It Is Used

The RYB162 Explosion Proof Differential Pressure Transmitter is used when a process requires safe, accurate and stable measurement of pressure difference. In oil and gas, chemical and industrial plants, differential pressure measurement is important for monitoring pipelines, tanks, filters, pumps, flow systems and process equipment.

It is used because it provides:

Accurate differential pressure measurement for gas and liquid applications.
