Honeywell STT170 Temperature Transmitter

Honeywell STT170 Smart temperature transmitters are economical Temperature Transmitters ideally suited towards basic 4-20mA temperature monitoring applications and OEM supply.   The STT170 Temperature transmitter is physically a small size which makes it compatible with even the smallest DIN B head housing. The STT171, STT173 and STT17H are all configurable using STT17C configuration tool and PC.


This product line is discontinued and replaced with the Honeywell STT750 temperature transmitter range


STT170 converts low level inputs from a variety of temperature sensors such as RTDs/TCs into current output.  As Honeywell channel partners, Fluidic offer the Honeywell STT170 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 association with Okazaki and H&B Sensors for more information on these assemblies (Okazakis’s Vortexwell is a particularly unique offering).

The Honeywell STT170 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.
