New Original Honeywell Intelligent 4-20mA Programmable Temperature Transmitter STT17H-BS
product descriptionHoneywell STT170 series programmable temperature transmitters provide an economical and efficient solution for temperature monitoring applications. Compared with directly connected temperature sensor monitoring points, the STT170 series transmitters provide greater accuracy, safety and reliability while reducing the cost of wiring. These transmitters will automatically linearize the temperature output signal defined by the user established range upper limit and range lower limit. In addition, users can set upper or lower limit alarms to activate in the event of sensor failure. specification
Features• RTD, TC, Ohm, or mV Input • Extremely High Measurement Accuracy • HART® Communication • Galvanic isolation • For DIN form B sensor head mounting
Application• Linearised temperature measurement with Pt100, Ni100 or thermocouple sensor. • Difference or average temperature measurement of 2 resistance or thermocouple sensors. • Conversion of linear resistance variation to a standard analogue current signal, for instance from valves or Ohmic level sensors. • Amplification of a bipolar mV signal to a standard 4-20mA current signal. • Connection of up to 15 transmitters to a digital 2-wire signal with HART® communication.
technical feature• Within a few seconds the user can program the STT17H to measure temperatures within all ranges defined by the norms. • The RTD and resistance inputs have cable compensation for 2-, 3-, and 4-wire connection. • Continuous check of vital stored data for safety reasons. • Sensor error detection according to the guidelines in NAMUR NE 89.
The outputs of max. 15 transmitters can be connected in parallel for a digital HART® communication on 2-wires. Before it is connected, each transmitter must be configured with a unique number from 1 to 15. If two transmitters are configured with the same number, both will be excluded. The transmitters must be programmed for multidrop mode (with a fixed output signal of 4 mA). Maximum current in the loop is therefore 60 mA. The communication is either by means of a HART® communicator or a HART® modem. The STT17C configuration software can configure the individual transmitter for multidrop mode and provide it with a unique polling address.
