The STT170 is Honeywell’s economy-tier family of temperature transmitters to flank the existing mid-tier STT700 and high-tier STT750 & STT850 temperature transmitters. It helps convert low level signals from temperature sensors such as RTDs and TCs into current signals and is capable of transmitting long distances through noisy plant environments.  The STT170 line consists of three temperature transmitters and one configuration tool:

• STT171 – Analog output, RTD-only sensor input
• STT173  – Analog output, RTD or thermocouple sensor input
• STT17H – HART output, RTD & thermocouple sensor input
• STT17C  – PC-based configuration tool for configuring the STT171, STT173 and STT17H transmitters

The Honeywell STT170 series of programmable temperature transmitters provide cost-effective solutions for temperature monitoring applications. Compared to direct-wired temperature sensor monitoring points, the STT170 series of transmitters delivers increased accuracy, safety and reliability while also reducing wiring costs. These transmitters automatically linearize the temperature output signal bounded by the upper range value and lower range value established by the user. In addition, the user can program high or low limit alarms to activate in the case of sensor failure.
