Honeywell STT250 Temperature Transmitter

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.

This product line is discontinued and replaced with the Honeywell STT750 Temperature Transmitter Range

STT250 converts low level inputs from a variety of temperature sensors such as RTDs/TCs into current output and is capable of transmission over long distances through noisy plant environments.  As Honeywell channel partners, Fluidic offer the Honeywell STT250 temperature transmitter puck included in a full RTD/temperature transmitter assembly with probe and electrical head, and with thermowell where appropriate.  See information on our assossiation with Okazaki and H&B Sensors for more information on these assemblies (Okazaki’s Vortexwell is a particularly unique offering).

The Honeywell STT250 is available in different forms – as a module, capable of getting into a temperature sensor head or Mounted in the DIN Rail panel or Field Mounted on a two inch pipe. These units come with several communication options which include 4 to 20ma analog output, HART Protocol  and DE Protocol.
