The SmartLine STT850 temperature transmitters offer the following features:
The temperature transmitters can simultaneously support an integral probe and external inputs, including a combination of thermocouple, RTD and discrete inputs. When the integral probe is a thermocouple, two external thermocouples or one external RTD can be wired to the temperature transmitters. An external thermocouple or an external RTD can be wired to these wireless transmitters when the integral probe is an RTD.
STT350 Temperature Transmitter converts low level signals from temperature sensors into current signals capable of long distance transmission. In view of its unique design and robust galvanic isolation, the temperature measurement is immune to electromagnetic and RF interference, helping users measure temperature in noisy industrial environments as seen in mineral and metal industries. In addition, it helps users measure temperature accurately leading to improved energy efficiency and product quality.
It is available in the field mounted, wall mounted and DIN Rail mounted versions.
STT250 Smart temperature transmitters are used to monitor and control temperature of critical rotating and static assets thereby enhancing equipment health and performance. In several process heating applications, these are employed to control process temperatures leading to energy efficiency and product quality. STT250 converts low level inputs from a variety of temperature sensors such as RTDs/TCs into current output and is capable of transmission over long distances through noisy plant environments. STT250 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 Version 5/6 and DE Protocol.
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:
