Honeywell STD800 SMARTLINE Differential Pressure Transmitters

Honeywell STD800 Smartline® smart differential pressure transmitters are high accuracy, fast response, modular differential pressure transmitters.  Of traditional 54mm centers, kidney flange design with a range of wetted and non wetted material options, the Smartline® STD800 differential pressure transmitters are suited to a wide range of industrial process control applications.


Honeywell Smartline® STD800 family comprise of the following ranges

  • STD810 range 0…25mbar with a 25:1 turndown
  • STD820 range 0…1000mbar with a 400:1 turndown
  • STD830 range 0…7bar with a 100:1 turndown
  • STD870 range 0…210bar with a 100:1 turndown


All Honeywell  ST800 Smartline® smart pressure transmitters are compensated for pressure and temperature, CLICK HERE to download the Honeywell Accuracy calculator and calculate Total Probable Error for your measurement range.  Additionally all Honeywell’s SmartLine® smart pressure transmitters offer a modular pressure transmitter design.  Displays, transmitter pucks, process heads, gaskets and other associated parts can be held in stock to be assembled for each custom install as required.


STD800  Smartline® smart differential pressure transmitters, features and benefits…

  • Modular design allows field modification & stocking of spares
  • Uncertainty to within ±0.025% (we can supply a Total Probable Error (TPE) uncertainty chart for your defined range)
  • Stability to within ±0.01% of URL per year for 10 years
  • Static pressure and temperature compensation
  • Complete reverse polarity insensitivity, undamaged by and will still operate with cross wiring install
  • Fast response times within 80ms
  • Remote messaging facility with historical data information when ordered with advanced graphical display
  • NAMUR NE43 Compliant Outputs
    (Normal Limits 3.8 – 20.5 mA, Failure Mode ≤3.6mA low or ≥21.0mA high)
