Compact pressure transmitter

I. Product introduction

RST-121 compact pressure transmitter uses a high performance pressure sensor chip, with advanced circuit processing and temperature compensation technology, the pressure change into a linear current or voltage signal. The product is small in size, easy to install and anticorrosive with stainless steel enclosure. It is suitable for measuring media such as gas and liquid compatible with the contact part material. It can be used to measure gauge pressure, negative pressure and absolute pressure.

Ii. Product features

1. 316L stainless steel isolation diaphragm structure

2. Reverse polarity and current limiting protection

3. Anti-vibration, anti-impact and anti-RF electromagnetic interference

4. Strong ability of overload and anti-interference, economic and practical stability
