Original Honeywell RTD STT170 series of programmable temperature transmitters STT3000

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 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.

STT171 FEATURES

• Analog 4-20 mA output

• RTD or Ohm input

• DIN form B headmount

• NAMUR NE43 sensor error response

• Configurable using STT17C configuration tool and PC

STT170 is a measurement solution for temperature monitoring applications. It helps end users and Original Equipment Manufacturers (OEMs) achieve reliable and accurate temperature measurement in a cost-effective manner.

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
