High-Temperature Pressure Transmitter With 500°C Capability, ±0.03%FS/C Drift, and 4-20mA Output for Industrial Process Control

High - Temperature Pressure Transmitter Series

Product Introduction

The high - temperature pressure transmitter adopts a diffused silicon pressure core as the sensing element. The built - in processing circuit converts the millivolt signal of the sensor into standard voltage, current, and frequency signals for output. It can be directly connected to computers, control instruments, display instruments, etc., and supports long - distance signal transmission. The high - temperature type adopts an integrated all - stainless - steel structure. After multiple stainless - steel welding processes, an all - solid - state design is achieved, allowing it to be used for a long time in harsh environments. Additionally, the product is easy to install and has high anti - interference and anti - impact properties.
