Honeywell STT250 Series Smart Temperature Transmitter

STT250 Series Smart Temperature Transmitter Introduction

Honeywell STT250 Smart temperature transmitters are HART enabled Temperature Transmitters aimed towards the monitoring and control of critical process temperature applications. In several process heating applications, the Honeywell STT250 is employed to control process temperatures leading to energy efficiency and product quality.

The STT250 Series Smart Temperature Transmitter is a microprocessor based unit suitable for accepting a wide variety of thermocouple and resistance temperature detector sensor inputs or direct ohm or milli-volt inputs and providing a 2 wire 4-20 mA “Analog”, digital “DE”, or analog “HART” proportional output. The transmitter offers high accuracy and stability together with wide flexibility to suit a wide range of applications. All adjustments and operational settings are implemented through the Smart Field Communicator (DE) or the HART communicator (HART). Both field communicators access the transmitter by connecting across the 4-20 mA wiring in parallel with the STT250 anywhere along the wiring up to 1500 meters from the transmitter for both the DE and HART protocol versions.
