SMART PRESSURE TRANSMITTER WITH HART COMMUNICATION-ATNPRT-100S

SMART PRESSURE TRANSMITTER WITH HART COMMUNICATION

ATNPRT-100S can accurately measure the pressure of gases,vapors and liquids used in refineries, petrochemicals, oil and gas,power, chemical industries, food processing and pharmaceutical industries. Based on a mechanical and rugged silicon sensor and capacitive sensor, the ATNPRT-100S(GP & AP) is suitable for Absolute and Gauge pressure measurements. It is having wide ranges of pressure with high accuracy and linearity output in the form of electrical signal 4-20 mA DC with HART communication.
