Honeywell ST700 Diaphragm Pressure Transmitter: High-Performance Smart Pressure Measurement Solution

The ST700 pressure transmitter is a high-precision pressure transmitter produced by Honeywell. It adopts advanced technology and structure, featuring high precision, high reliability, low cost and excellent programmable performance. It can be used to control various complex pressure systems, with an accuracy of up to 0.25%, and can meet the requirements of various application scenarios. The structure of the ST700 pressure transmitter includes a pressure sensor, an electronic regulation module and an electronic display module. The pressure sensor can detect the changes in pressure within the system and transmit the signal to the electronic regulation module. The electronic regulation module regulates the pressure sensor through a flexible circuit, thereby achieving a high-precision transmitter. The electronic display module can show the pressure changes in real time, so as to respond quickly to the pressure changes and control the system.
