The DPT 200 is BD|SENSORS' differential pressure transmitter for the process industry, pairing a stainless-steel sensor with a compact aluminium die-cast housing to measure from 1 mbar to 20 bar at up to 400 bar static pressure.

Why 0.075% FSO accuracy on a differential transmitter?

Orifice metering and filter differential monitoring convert a reading error straight into a flow error. At 0.075% FSO per IEC 60770, the DPT 200 sits a full accuracy class above common 0.1% transmitters, so a single instrument re-ranges from its 20 bar URL down to a 1/100 span — no spare per range. With HART communication, range and zero are reconfigured in the field, not at the bench.

What does a 100:1 turndown actually change in the plant?

A conventional 10:1 transmitter forces a different instrument for every measuring range; the DPT 200's 100:1 turndown lets one unit be re-ranged over HART to cover the span you need, while 400 bar static pressure keeps it on high-pressure lines where cheaper units drift out of specification. The aluminium die-cast housing reaches IP67 with an optional ATEX version, so it deploys directly in oil and gas, chemical and energy plants — and a loop-powered HART barrier keeps communication transparent in hazardous areas.

• Measuring range 1 mbar to 20 bar, static pressure to 400 bar
• Accuracy 0.075% FSO (IEC 60770), turndown 100:1
• 2-wire 4–20 mA with HART, linear or square-root output
• Aluminium die-cast housing, IP67, optional ATEX
• Flange and valve-mount process connections

Against a separate 0.1% transmitter per range, the DPT 200 swaps a HART re-range for a spare instrument — the reason one transmitter carries a whole metering skid.
