DG Smart Pressure Sensor

Our SIL capable pressure transmitter for combustion air and fuel gases features digital communication via MODBUS TCP, 4-20mA NAMUR Analog output, local LCD display, and LED indicators.

Overview
Introducing our high-quality pressure transmitter, designed to provide accurate and precise readings for low-pressure combustion air and fuel gases applications. Our pressure transmitter is packed with advanced features and capabilities that make it the ultimate instrument to improve and optimize your combustion system. With its digital communication via MODBUS TCP and fail-safe 4-20mA NAMUR Analog output, our pressure transmitter is designed to work seamlessly with any control system. It provides accurate and reliable readings, making it perfect for use in a wide range of combustion systems.

Our pressure transmitter also features a local LCD display and LED indicators, making it easy to monitor and regulate pressure in real-time. With this level of accuracy, you can be confident that your pressure readings are precise, enabling you to make informed decisions and optimize your processes for maximum efficiency.

One of the key features of our pressure transmitter is its SIL2 capability in accordance with IEC 61508 via fail-safe 4-20 mA analog output. This makes our transmitter a safe and reliable solution for any low-pressure combustion air and fuel gases application. We understand that safety is a top priority in these industries, and our pressure transmitter is designed to meet and exceed the most stringent safety requirements.

DG Smart is available in two designs: (1) as a relative pressure sensor, (2) as a differential pressure sensor. Find out more by studying the technical information sheet on “Docuthek”.
