1. Product Range overview:
The SmartLine family pressure transmitters are designed around a high performance piezo-resistive sensor.
This one sensor actually integrates multiple sensors linkingprocess pressure measurement with on-board static pressure (DP Models) and temperature compensation measurements. This level of performance allows the ST 700 to replace m ost competitive transmitters available today.
2. Introduction:
Part of the SmartLine® family of products, the STF700 is suitable for monitoring, control and data acquisition.
STF700 products feature piezoresistive sensor technology combing pressure sensing with on chip temperature compensation capabilities providing high accuracy, stability and performance over a wide range of application pressures and temperatures.
The SmartLine family is also fully tested and compliant with Experion ® PKS providing the highest level of compatibility assurance and integration capabilities.
SmartLine easily meets the most demanding application needs for pressure measurement applications.
