STT170 Smart Temp
The Honeywell STT170 series of programmable temperature transmitters provides 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 bound 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.
What Is It?
The STT170 is Honeywell’s economy-tier family of temperature transmitters to flank the existing mid-tier STT250 and high-tier STT350 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 four 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
STT17F – FOUNDATION Fieldbus protocol, RTD & thermocouple sensor input
STT17C – PC-based configuration tool for configuring the STT171, STT173 and STT17H transmitters
