Explosion-proof housing allows it to stand up to the most hazardous and demanding applications.

ControlAir’s Dahl P290 P/I transducer represents outstanding value in pneumatic to current technology. All solid state circuitry converts standard 3-15, 3-27 or 6-30 psig instrument air into 4-20 or 10-50 mA outputs (4-20 mA only for FM and CSA approval) with uncompromising accuracy and durability. Custom pressure ranges are also available. P290 serves in high-density and panel-mounted applications and is available with high density DIN rail adapters, offering space saving flexibility with easy plug-in installation.

Input

3-15 psig (0.2-1 bar), 3-27 psig (0.2-1.8 bar), 6-30 psig (0.4-2 bar)

Outputs (2 wire)

10-50 mA, 4-20 mA

Input, Maximum

3 times full scale without calibration 4 times full scale without failure

Repeatability

±0.10% of span max; ±0.03% of span typical

Connections - Signal Air

1/8" NPT female;Electrical Wiring: Miniature terminal block accepts solid or stranded wire up to 14 AWG

In-process Output Monitoring

Current: For accurate reading, ampmeter must have less than 20 Ω input resistance on 4-20 mA output (0.40 VDC drop)

Mounting Position Effect

None

Calibration Adjustments

Multiturn span and zero potentiometers with approximately ±20% of span adjustment range

Temperature Range (Storage)

-60° to 161°F (-51° to 72°C)

Ambient Temperature Limits

-40° to 161°F (-40° to 72°C)

RFI/EMI Effect

Meets or exceeds SAMA PMC 33.1, 1978, 2-abc: 0.1% of span at 10 volts/meter

Power Supply

10 VDC min. to 42 VDC max. at input terminals. Can indefinitely withstand up to 100 VDC without failure

Power Supply Stability

Less than 0.005% of span change in output per volt change at the input terminals

Temperature Stability

Span and Zero: ±0.007% of span per ˚F maximum deviation from 77˚F calibration

Response Time to 99% of step change

10 m Sec

Resolution

Infinite

Accuracy

± 0.15% of span guaranteed; ±0.10% of span typical.
