7NG0410-1BB00-0NA0 SIEMENS Exclusive SITRANS TH420 Temperature Transmitter Original Brand New

The SIEMENS 7NG0410-1BB00-0NA0 SITRANS TH420 is a highly reliable temperature transmitter designed for advanced process applications across various industries. Engineered for installation in a connection head type B according to DIN 43729, this transmitter features two separate configurable inputs and a galvanically isolated 2-wire output. With HART communication protocol (4–20 mA), it ensures efficient signal transmission and integration into modern automation systems. Its ability to support redundant input circuits increases measurement availability and minimizes downtime in demanding environments.

Offering compatibility with RTD Pt100 sensors and multiple thermocouples, the transmitter delivers universal input flexibility. The device can be configured to connect two independent circuits, enabling drift detection and preventive maintenance planning. The SITRANS TH420 is designed without a local enclosure, supporting both head-mounted and rail-mounted installations. With safety certifications such as ATEX, IECEx, EACEx, CSA, FM, NEPSI, Inmetro, and UKEX, the transmitter is suitable for hazardous areas requiring intrinsic safety, non-incendive field wiring, or increased safety protection.

Overview

This compact two-wire head-mounted transmitter offers a HART and Profibus PA communication interface. Its universal input allows connection to almost any type of temperature sensor, including resistance thermometers, thermocouples, linear resistors, potentiometers, and voltage sources. The device is optimized for use in connection heads type B or larger, supporting redundant operation for high process reliability.

Application

The SITRANS TH420 temperature transmitter is versatile and can be applied in multiple industrial sectors, from energy and chemical processing to food and pharmaceuticals. Its compact size ensures straightforward installation, while dual input mode enables redundant measurement for continuous monitoring. With drift detection functionality, maintenance intervals can be better scheduled, reducing operational costs and improving efficiency. The unit is particularly valuable for environments that require compliance with global safety standards while ensuring accurate and consistent temperature measurement under challenging process conditions.
