NAME:JC670 Flat Diaphragm Pressure Transmitter

The flat diaphragm pressure transmitter is used in hygienic pressure pipelines, food and beverage processing, medical and pharmaceutical, sewage treatment, viscous medium pressure measurement.

JC670 Flat Diaphragm Pressure Transmitter Introduction

JC670 flat diaphragm pressure transmitter adopts imported high-accuracy and high-stability pressure sensor module to covert the absolute pressure or the gauge pressure of the measured medium into 4 ~ 20mA, 1 ~ 5V / 0 ~ 5V standard electrical signal through high-reliability amplification circuit and precise temperature compensation. High-quality sensor and encapsulation technology of full seal welding as well as improved assembling process have ensured excellent quality and best performance of this series of product.

Tips of Selection
1. The measured medium shall be compatible with the material contacting with the product.
2. The code E, an additional function code for selection, namely, intrinsically safe explosion-proof Ex iaIICT6, must be power supplied via safety barrier.
3. Please contact us for other special requirements and clearly indicate them in the order.
4. During the field installation of flat diaphragm, the correct sealing method shall be adopted to prevent the installation stress influencing product stability.
