Detailed introduction of HQ316 oil pressure sensor The 316 series oil pressure sensor uses high-performance pressure sensitive chip, combined with advanced circuit processing and temperature compensation technology, to convert pressure changes into linear current or voltage signals. The product is small in size, easy to install, and is insulated by a stainless steel case. It is suitable for measuring gas and liquid media compatible with the material of the contact part. It can be used to measure gauge pressure, negative pressure and absolute pressure. Application: This product is widely used in water industry, oil refinery, sewage treatment plant, building materials, light industry, machinery and other industrial fields to achieve measurement of liquid, gas and vapor pressure.

HQ316 oil pressure sensor features: reverse polarity and current limiting protection; laser temperature regulation temperature compensation; programmable control; anti-vibration, anti-shock, anti-radio electromagnetic interference; overload and anti-interference ability, economical and practical stability.
