Product Description

The Honeywell STF828-E1HS6A-11F-A-CDC-11S-A-00A0-00-0000 is a high-precision flange-mounted pressure transmitter from Honeywell's SmartLine® STF800 series. Designed for critical applications such as custody transfer of natural gas and energy and material balances, this transmitter offers exceptional accuracy and stability. It features a piezoresistive sensor that integrates differential pressure, static pressure, and temperature measurements, providing a fully compensated output signal. The STF828 model specifically offers a pressure range from -400 to 400 inH₂O (-1000 to 1000 mbar) with a turndown ratio of up to 100:1, making it suitable for high-accuracy level measurements in pressurized and unpressurized vessels in the chemical and hydrocarbon industries.
