CYB2600 series micro differential pressure transmitter
1 Introduction
CYB2600 series micro differential pressure transmitter adopts silicon MEMS Micro Pressure chip. After temperature compensation, linear compensation, signal amplification, V / I conversion, surge, reverse polarity protection and other transmission circuit signal processing, CYB2600 series micro differential pressure transmitter outputs industrial standard 4-20mA signal. All digital calibration, no movable potentiometer, temperature drift performance, stability has been improved.
This series of products adopt two isolation methods. Less than 5kPa, the chip is protected by elastic silicon gel. It is mainly used for differential pressure measurement of non corrosive gases for silicon and silicon gel. The range of 5kPa and above is measured. The chip is protected by 316L stainless steel isolation diaphragm, and is filled with silicone oil. It is suitable for medium measurement of stainless steel without corrosion.
2 Features
This series of transmitters are used in petroleum, chemical, metallurgy, electric power, textile, electronics, medicine, food, environmental protection and other fields, and more widely used in HVAC, purification plant and boiler automatic detection.

7 Precautions
7.1 When receiving the product, please check whether the package is in good condition, and check whether the transmitter model and specification are consistent with the product you purchased.
7.2 Please keep the verification certificate and certificate, and return it with the product during maintenance.
7.3 Pay attention to the installation direction of the transmitter. Generally, the transmitter should be horizontally debugged and installed horizontally; the vertical installation should be explained when ordering or adjusting the zero point of the secondary instrument.
7.4 The transmitter shall not be installed in the environment of mechanical vibration and strong electromagnetic interference.
7.5 In low temperature environment, in order to ensure the accurate measurement of pressure, it is necessary to ensure the fluidity of the measured medium.
7.6 The transmitter is a precision instrument and should be stored in a dry and ventilated indoor environment to avoid direct sunlight.
