6bar 10bar RS485 Digital Water Pressure Sensor / Low Power 3V Waterproof Pressure Sensor

Product Introduction

The PTM-1H CE Low Cost Price Industrial Water Air Gas Liquid Pressure Sensor is a silicon MEMS strain gauge sensor which is glass bonded to a stainless steel diaphragm.It avoids influences on product caused by temperature, humidity, mechanical fatigue and medium, thus to improve its longterm stability in the industrial environment. Its pressure chamber is made of imported 17-4PH stainless steel in an integrated way without welding seams or O-rings, free of leakage troubles. Digital circuits capable of strong RFI & EMI resistance and automatic temperature compensation are installed inside the transmitter and the transmitter is featured with the strong interference resistance, wide temperature compensation scope and flexible & various output forms, etc. The series products provide several optional pressure connectors and electric output forms for customers.
