HC-25Micro pore water pressure sensor


HC-25 Micro Pore Water Pressure Sensor and Transmitter

Product introduction

Due to the requirements on the measured flow field and location, the variation of the pulsating flow field must be reproduced when the pressure is measured in situ and without interfering with the flow field state. This is often due to the miniaturization of the external dimensions of the sensor. The rigorous requirements, HC-25 micro pore water pressure sensor and transmitter are precisely designed for the above working conditions, this series of products is ceramic filter, stainless steel structure, using micro-machined silicon diaphragm as the core component, high-precision integration, use The international advanced miniaturization production and packaging process has been exquisite and ingenious miniature packaging. The product is small in size, compact in structure, light in weight, durable, and has excellent dynamic and static characteristics. This series of products are particularly suitable for civil simulation and centrifuge simulation. Such as use, widely used in civil engineering, rock and soil mechanics, earthquake monitoring.
