The NH3151 series pressure/differential pressure/level transmitters are the latest generation of intelligent digital measuring instruments. They adopt high-precision silicon sensor technology and feature high accuracy, good stability, strong anti-interference performance, and a user-friendly interface. Parameters can be set and modified through on-site button operations or remote HART fieldbus communication. It is functionally rich and has a wide range of applications, making this transmitter highly suitable for industrial needs. Despite having numerous setting options, the operation remains simple and easy to master.

The NH 3151 series is specially designed for high-stability measurement applications, with a maximum working pressure of up to 100 MPa (depending on the specific configuration).
· It can achieve functions such as migration, range adjustment, zero adjustment, damping, and data recovery.
· It adopts the internationally leading direct digital frequency synthesis (DDS) technology to achieve high precision.
· It is truly fully isolated, with an isolation voltage between the sensor and the main circuit reaching up to 1500 VDC.
· It is equipped with comprehensive anti-interference devices and multiple-level protection circuits to ensure high reliability in the field.
· There is also a PROFIBUS-PA protocol product available as an option, with the same functional indicators, and it can be connected to the Siemens S7 system.
