Specs

Device Type: SmartLine temperature transmitter Model: HONEYWELL STT700-1H-A20-U0020-90A0-11C-CF1W1-00000 Input: Universal RTD, thermocouple, mV Output: 4-20mA, HART 7 Safety Level: SIL 2 / SIL 3 capable Update Time: 500ms for single input Power Supply: 12VDC to 42VDC loop supply Mounting: Head mount / pipe mount / wall mount Certification: ATEX, IECEx, FM, CSA Protection Class: IP66 Application: Process temperature monitoring and control

Principle

The HONEYWELL STT700-1H-A20-U0020-90A0-11C-CF1W1-00000 receives raw resistance or voltage signals from field temperature sensors. Internal signal conditioning and microprocessor circuits convert sensor readings into standardized 4-20mA loop signal. HART digital data transmits measured value, tag information, diagnostic status and sensor health to the host control system. The transmitter continuously monitors sensor continuity and loop condition, and triggers alarm output when open circuit, short circuit or out-of-range temperature occurs.

Applications

The HONEYWELL STT700-1H-A20-U0020-90A0-11C-CF1W1-00000 is used for temperature loop measurement in chemical, oil and gas, power and water treatment plants. It serves furnace, reactor, pipeline and heat exchanger temperature monitoring for DCS and safety instrumented systems. The HONEYWELL STT700-1H-A20-U0020-90A0-11C-CF1W1-00000 applies to spare renewal and calibration replacement of existing SmartLine temperature instrumentation. It also supports building energy management and industrial test bench temperature acquisition.
