Miniature Flush Diaphragm Pressure Sensor_Manufacturer_OEM/ODM Custom Solutions

Miniature Flush Diaphragm Pressure Sensor Product Introduction

HPE-3 is a miniature sensor designed specifically for measuring static and dynamic pressure in various conditions, including harsh environments. It is made of stainless steel and has a standard measurement range of 0-20 bar to 0-70 bar. HPE-3 has unique features that minimize zero-point deviation caused by installation torque.

HPE-3 can be integrated with different electronic components to achieve amplified output: 0.5-4.5V, 0-5V, 4-20mA.
