Honeywell STT3000 Smart Temperature Transmitter Series STT170 Measurement Solution

STT170 Smart Temperature Transmitter

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.

STT171 Features

• Analog 4-20 mA output.

• RTD or Ohm input.

• DIN form B head mount.

• NAMUR NE43 sensor error response.

• Configurable using STT17C configuration tool and PC.

STT173 Features

• Analog 4-20 mA output

• RTD, T/C, Ohm or mV input

• DIN form B head mount

• NAMUR NE43 sensor error response

• Configurable using STT17C configuration tool and PC

• Galvanic isolation

STT17H Features

• HART™/4-20 mA output

• RTD, T/C, Ohm or mV input

• Single or dual (difference or average) sensor input

• DIN form B head mount

• HART Multidrop capable

• NAMUR NE43 sensor error response

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 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
